It supports a wide variety of video -file formats, audio and video codecs, and subtitle types. Special input URL -types are available to read input from a variety of sources other than disk -files. Depending on platform, a variety of different video and audio output -methods are supported. -.sp -Usage examples to get you started quickly can be found at the end of this man -page. -.SH INTERACTIVE CONTROL -.sp -mpv has a fully configurable, command\-driven control layer which allows you -to control mpv using keyboard, mouse, or remote control (there is no -LIRC support \- configure remotes as input devices instead). -.sp -See the \fB\-\-input\-\fP options for ways to customize it. -.sp -The following listings are not necessarily complete. See \fBetc/input.conf\fP for -a list of default bindings. User \fBinput.conf\fP files and Lua scripts can -define additional key bindings. -.sp -See also \fB\-\-input\-test\fP for interactive binding details by key, and the -\fI\%stats\fP built\-in script for key bindings list (including print to terminal). -.SS Keyboard Control -.INDENT 0.0 -.TP -.B LEFT and RIGHT -Seek backward/forward 5 seconds. Shift+arrow does a 1 second exact seek -(see \fB\-\-hr\-seek\fP). -.TP -.B UP and DOWN -Seek forward/backward 1 minute. Shift+arrow does a 5 second exact seek (see -\fB\-\-hr\-seek\fP). -.TP -.B Ctrl+LEFT and Ctrl+RIGHT -Seek to the previous/next subtitle. Subject to some restrictions and -might not always work; see \fBsub\-seek\fP command. -.TP -.B Ctrl+Shift+Left and Ctrl+Shift+Right -Adjust subtitle delay so that the next or previous subtitle is displayed -now. This is especially useful to sync subtitles to audio. -.TP -.B [ and ] -Decrease/increase current playback speed by 10%. -.TP -.B { and } -Halve/double current playback speed. -.TP -.B BACKSPACE -Reset playback speed to normal. -.TP -.B Shift+BACKSPACE -Undo the last seek. This works only if the playlist entry was not changed. -Hitting it a second time will go back to the original position. -See \fBrevert\-seek\fP command for details. -.TP -.B Shift+Ctrl+BACKSPACE -Mark the current position. This will then be used by \fBShift+BACKSPACE\fP -as revert position (once you seek back, the marker will be reset). You can -use this to seek around in the file and then return to the exact position -where you left off. -.TP -.B < and > -Go backward/forward in the playlist. -.TP -.B ENTER -Go forward in the playlist. -.TP -.B p / SPACE -Pause (pressing again unpauses). -.TP -.B \&. -Step forward. Pressing once will pause, every consecutive press will -play one frame and then go into pause mode again. -.UNINDENT -.INDENT 0.0 -.TP -.B , -Step backward. Pressing once will pause, every consecutive press will -play one frame in reverse and then go into pause mode again. -.TP -.B q -Stop playing and quit. -.TP -.B Q -Like \fBq\fP, but store the current playback position. Playing the same file -later will resume at the old playback position if possible. -.TP -.B / and * -Decrease/increase volume. -.TP -.B 9 and 0 -Decrease/increase volume. -.TP -.B m -Mute sound. -.TP -.B _ -Cycle through the available video tracks. -.TP -.B # -Cycle through the available audio tracks. -.TP -.B f -Toggle fullscreen (see also \fB\-\-fs\fP). -.TP -.B ESC -Exit fullscreen mode. -.TP -.B T -Toggle stay\-on\-top (see also \fB\-\-ontop\fP). -.TP -.B w and W -Decrease/increase pan\-and\-scan range. The \fBe\fP key does the same as -\fBW\fP currently, but use is discouraged. -.TP -.B o (also P) -Show progression bar, elapsed time and total duration on the OSD. -.TP -.B O -Toggle OSD states between normal and playback time/duration. -.TP -.B v -Toggle subtitle visibility. -.TP -.B j and J -Cycle through the available subtitles. -.TP -.B z and Z -Adjust subtitle delay by +/\- 0.1 seconds. The \fBx\fP key does the same as -\fBZ\fP currently, but use is discouraged. -.TP -.B l -Set/clear A\-B loop points. See \fBab\-loop\fP command for details. -.TP -.B L -Toggle infinite looping. -.TP -.B Ctrl + and Ctrl \- -Adjust audio delay (A/V sync) by +/\- 0.1 seconds. -.TP -.B Shift+g and Shift+f -Adjust subtitle font size by +/\- 10%. -.TP -.B u -Switch between applying no style overrides to SSA/ASS subtitles, and -overriding them almost completely with the normal subtitle style.

All options except \fIflag\fP options (or -choice options which include \fByes\fP) require a parameter in the form -\fB\-\-option=value\fP\&. -.sp -One exception is the lone \fB\-\fP (without anything else), which means media data -will be read from stdin. Also, \fB\-\-\fP (without anything else) will make the -player interpret all following arguments as filenames, even if they start with -\fB\-\fP\&. (To play a file named \fB\-\fP, you need to use \fB\&./\-\fP\&.) -.sp -Every \fIflag\fP option has a \fIno\-flag\fP counterpart, e.g. the opposite of the -\fB\-\-fs\fP option is \fB\-\-no\-fs\fP\&. \fB\-\-fs=yes\fP is same as \fB\-\-fs\fP, \fB\-\-fs=no\fP -is the same as \fB\-\-no\-fs\fP\&. -.sp -If an option is marked as \fI(XXX only)\fP, it will only work in combination with -the \fIXXX\fP option or if \fIXXX\fP is compiled in. -.SS Legacy option syntax -.sp -The \fB\-\-option=value\fP syntax is not strictly enforced, and the alternative -legacy syntax \fB\-option value\fP and \fB\-option=value\fP will also work. This is -mostly for compatibility with MPlayer. Using these should be avoided. Their -semantics can change any time in the future. -.sp -For example, the alternative syntax will consider an argument following the -option a filename. \fBmpv \-fs no\fP will attempt to play a file named \fBno\fP, -because \fB\-\-fs\fP is a flag option that requires no parameter. If an option -changes and its parameter becomes optional, then a command line using the -alternative syntax will break. -.sp -Until mpv 0.31.0, there was no difference whether an option started with \fB\-\-\fP -or a single \fB\-\fP\&. Newer mpv releases strictly expect that you pass the option -value after a \fB=\fP\&. For example, before \fBmpv \-\-log\-file f.txt\fP would write -a log to \fBf.txt\fP, but now this command line fails, as \fB\-\-log\-file\fP expects -an option value, and \fBf.txt\fP is simply considered a normal file to be played -(as in \fBmpv f.txt\fP). -.sp -The future plan is that \fB\-option value\fP will not work anymore, and options -with a single \fB\-\fP behave the same as \fB\-\-\fP options. -.SS Escaping spaces and other special characters -.sp -Keep in mind that the shell will partially parse and mangle the arguments you -pass to mpv. For example, you might need to quote or escape options and -filenames: -.INDENT 0.0 -.INDENT 3.5 -\fBmpv "filename with spaces.mkv" \-\-title="window title"\fP -.UNINDENT -.UNINDENT -.sp -It gets more complicated if the suboption parser is involved. The suboption -parser puts several options into a single string, and passes them to a -component at once, instead of using multiple options on the level of the -command line. -.sp -The suboption parser can quote strings with \fB"\fP and \fB[...]\fP\&. -Additionally, there is a special form of quoting with \fB%n%\fP described below. -.sp -For example, assume the hypothetical \fBfoo\fP filter can take multiple options: -.INDENT 0.0 -.INDENT 3.5 -\fBmpv test.mkv \-\-vf=foo:option1=value1:option2:option3=value3,bar\fP -.UNINDENT -.UNINDENT -.sp -This passes \fBoption1\fP and \fBoption3\fP to the \fBfoo\fP filter, with \fBoption2\fP -as flag (implicitly \fBoption2=yes\fP), and adds a \fBbar\fP filter after that. If -an option contains spaces or characters like \fB,\fP or \fB:\fP, you need to quote -them: -.INDENT 0.0 -.INDENT 3.5 -\fBmpv \(aq\-\-vf=foo:option1="option value with spaces",bar\(aq\fP -.UNINDENT -.UNINDENT -.sp -Shells may actually strip some quotes from the string passed to the commandline, -so the example quotes the string twice, ensuring that mpv receives the \fB"\fP -quotes. -.sp -The \fB[...]\fP form of quotes wraps everything between \fB[\fP and \fB]\fP\&. It\(aqs -useful with shells that don\(aqt interpret these characters in the middle of -an argument (like bash). These quotes are balanced (since mpv 0.9.0): the \fB[\fP -and \fB]\fP nest, and the quote terminates on the last \fB]\fP that has no matching -\fB[\fP within the string. (For example, \fB[a[b]c]\fP results in \fBa[b]c\fP\&.) -.sp -The fixed\-length quoting syntax is intended for use with external -scripts and programs. -.sp -It is started with \fB%\fP and has the following format: -.INDENT 0.0 -.INDENT 3.5 -.sp -.nf -.ft C -%n%string_of_length_n -.ft P -.fi -.UNINDENT -.UNINDENT -.INDENT 0.0 -.INDENT 3.5 -.IP "Examples" -.sp -\fBmpv \(aq\-\-vf=foo:option1=%11%quoted text\(aq test.avi\fP -.sp -Or in a script: -.sp -\fBmpv \-\-vf=foo:option1=%\(gaexpr length "$NAME"\(ga%"$NAME" test.avi\fP -.UNINDENT -.UNINDENT -.sp -Note: where applicable with JSON\-IPC, \fB%n%\fP is the length in UTF\-8 bytes, -after decoding the JSON data. -.sp -Suboptions passed to the client API are also subject to escaping. Using -\fBmpv_set_option_string()\fP is exactly like passing \fB\-\-name=data\fP to the -command line (but without shell processing of the string). Some options -support passing values in a more structured way instead of flat strings, and -can avoid the suboption parsing mess. For example, \fB\-\-vf\fP supports -\fBMPV_FORMAT_NODE\fP, which lets you pass suboptions as a nested data structure -of maps and arrays. -.SS Paths -.sp -Some care must be taken when passing arbitrary paths and filenames to mpv. For -example, paths starting with \fB\-\fP will be interpreted as options. Likewise, -if a path contains the sequence \fB://\fP, the string before that might be -interpreted as protocol prefix, even though \fB://\fP can be part of a legal -UNIX path. To avoid problems with arbitrary paths, you should be sure that -absolute paths passed to mpv start with \fB/\fP, and prefix relative paths with -\fB\&./\fP\&. -.sp -Using the \fBfile://\fP pseudo\-protocol is discouraged, because it involves -strange URL unescaping rules. -.sp -The name \fB\-\fP itself is interpreted as stdin, and will cause mpv to disable -console controls. (Which makes it suitable for playing data piped to stdin.) -.sp -The special argument \fB\-\-\fP can be used to stop mpv from interpreting the -following arguments as options. -.sp -When using the client API, you should strictly avoid using \fBmpv_command_string\fP -for invoking the \fBloadfile\fP command, and instead prefer e.g. \fBmpv_command\fP -to avoid the need for filename escaping. -.sp -For paths passed to suboptions, the situation is further complicated by the -need to escape special characters. To work this around, the path can be -additionally wrapped in the fixed\-length syntax, e.g. \fB%n%string_of_length_n\fP -(see above). -.sp -Some mpv options interpret paths starting with \fB~\fP\&. -Currently, the prefix \fB~~home/\fP expands to the mpv configuration directory -(usually \fB~/.config/mpv/\fP). -\fB~/\fP expands to the user\(aqs home directory. (The trailing \fB/\fP is always -required.) The following paths are currently recognized: -.TS -center; -|l|l|. -_ -T{ -Name -T} T{ -Meaning -T} -_ -T{ -\fB~~/\fP -T} T{ -If the subpath exists in any of the mpv\(aqs config directories -the path of the existing file/dir is returned. Otherwise this -is equivalent to \fB~~home/\fP\&. -Note that if \-\-no\-config is used \fB~~/foobar\fP will resolve to -\fBfoobar\fP which can be unexpected. -T} -_ -T{ -\fB~/\fP -T} T{ -user home directory root (similar to shell, \fB$HOME\fP) -T} -_ -T{ -\fB~~home/\fP -T} T{ -mpv config dir (for example \fB~/.config/mpv/\fP) -T} -_ -T{ -\fB~~global/\fP -T} T{ -the global config path, if available (not on win32) -T} -_ -T{ -\fB~~osxbundle/\fP -T} T{ -the macOS bundle resource path (macOS only) -T} -_ -T{ -\fB~~desktop/\fP -T} T{ -the path to the desktop (win32, macOS) -T} -_ -T{ -\fB~~exe_dir/\fP -T} T{ -win32 only: the path to the directory containing the exe (for -config file purposes; \fB$MPV_HOME\fP overrides it) -T} -_ -T{ -\fB~~old_home/\fP -T} T{ -do not use -T} -_ -.TE -.SS Per\-File Options -.sp -When playing multiple files, any option given on the command line usually -affects all files. Example: -.INDENT 0.0 -.INDENT 3.5 -.sp -.nf -.ft C -mpv \-\-a file1.mkv \-\-b file2.mkv \-\-c -.ft P -.fi -.UNINDENT -.UNINDENT -.TS -center; -|l|l|. -_ -T{ -File -T} T{ -Active options -T} -_ -T{ -file1.mkv -T} T{ -\fB\-\-a \-\-b \-\-c\fP -T} -_ -T{ -file2.mkv -T} T{ -\fB\-\-a \-\-b \-\-c\fP -T} -_ -.TE -.sp -(This is different from MPlayer and mplayer2.) -.sp -Also, if any option is changed at runtime (via input commands), they are not -reset when a new file is played. -.sp -Sometimes, it is useful to change options per\-file. This can be achieved by -adding the special per\-file markers \fB\-\-{\fP and \fB\-\-}\fP\&. (Note that you must -escape these on some shells.) Example: -.INDENT 0.0 -.INDENT 3.5 -.sp -.nf -.ft C -mpv \-\-a file1.mkv \-\-b \-\-\e{ \-\-c file2.mkv \-\-d file3.mkv \-\-e \-\-\e} file4.mkv \-\-f -.ft P -.fi -.UNINDENT -.UNINDENT -.TS -center; -|l|l|. -_ -T{ -File -T} T{ -Active options -T} -_ -T{ -file1.mkv -T} T{ -\fB\-\-a \-\-b \-\-f\fP -T} -_ -T{ -file2.mkv -T} T{ -\fB\-\-a \-\-b \-\-f \-\-c \-\-d \-\-e\fP -T} -_ -T{ -file3.mkv -T} T{ -\fB\-\-a \-\-b \-\-f \-\-c \-\-d \-\-e\fP -T} -_ -T{ -file4.mkv -T} T{ -\fB\-\-a \-\-b \-\-f\fP -T} -_ -.TE -.sp -Additionally, any file\-local option changed at runtime is reset when the current -file stops playing. If option \fB\-\-c\fP is changed during playback of -\fBfile2.mkv\fP, it is reset when advancing to \fBfile3.mkv\fP\&. This only affects -file\-local options. The option \fB\-\-a\fP is never reset here. -.SS List Options -.sp -Some options which store lists of option values can have action suffixes. For -example, the \fB\-\-display\-tags\fP option takes a \fB,\fP\-separated list of tags, but -the option also allows you to append a single tag with \fB\-\-display\-tags\-append\fP, -and the tag name can for example contain a literal \fB,\fP without the need for -escaping. -.SS String list and path list options -.sp -String lists are separated by \fB,\fP\&. The strings are not parsed or interpreted -by the option system itself. However, most -.sp -Path or file list options use \fB:\fP (Unix) or \fB;\fP (Windows) as separator, -instead of \fB,\fP\&. -.sp -They support the following operations: -.TS -center; -|l|l|. -_ -T{ -Suffix -T} T{ -Meaning -T} -_ -T{ -\-set -T} T{ -Set a list of items (using the list separator, escaped with backslash) -T} -_ -T{ -\-append -T} T{ -Append single item (does not interpret escapes) -T} -_ -T{ -\-add -T} T{ -Append 1 or more items (same syntax as \-set) -T} -_ -T{ -\-pre -T} T{ -Prepend 1 or more items (same syntax as \-set) -T} -_ -T{ -\-clr -T} T{ -Clear the option (remove all items) -T} -_ -T{ -\-remove -T} T{ -Delete item if present (does not interpret escapes) -T} -_ -T{ -\-del -T} T{ -Delete 1 or more items by integer index (deprecated) -T} -_ -T{ -\-toggle -T} T{ -Append an item, or remove if if it already exists (no escapes) -T} -_ -.TE -.sp -\fB\-append\fP is meant as a simple way to append a single item without having -to escape the argument (you may still need to escape on the shell level). -.SS Key/value list options -.sp -A key/value list is a list of key/value string pairs. In programming languages, -this type of data structure is often called a map or a dictionary. The order -normally does not matter, although in some cases the order might matter. -.sp -They support the following operations: -.TS -center; -|l|l|. -_ -T{ -Suffix -T} T{ -Meaning -T} -_ -T{ -\-set -T} T{ -Set a list of items (using \fB,\fP as separator) -T} -_ -T{ -\-append -T} T{ -Append a single item (escapes for the key, no escapes for the value) -T} -_ -T{ -\-add -T} T{ -Append 1 or more items (same syntax as \-set) -T} -_ -T{ -\-remove -T} T{ -Delete item by key if present (does not interpret escapes) -T} -_ -.TE -.sp -Keys are unique within the list. If an already present key is set, the existing -key is removed before the new value is appended. -.sp -If you want to pass a value without interpreting it for escapes or \fB,\fP, it is -recommended to use the \fB\-add\fP variant. When using libmpv, prefer using -\fBMPV_FORMAT_NODE_MAP\fP; when using a scripting backend or the JSON IPC, use an -appropriate structured data type. -.sp -Prior to mpv 0.33, \fB:\fP was also recognized as separator by \fB\-set\fP\&. -.SS Filter options -.sp -This is a very complex option type for the \fB\-\-af\fP and \fB\-\-vf\fP options only. -They often require complicated escaping. See \fI\%VIDEO FILTERS\fP for details. They -support the following operations: -.TS -center; -|l|l|. -_ -T{ -Suffix -T} T{ -Meaning -T} -_ -T{ -\-set -T} T{ -Set a list of filters (using \fB,\fP as separator) -T} -_ -T{ -\-append -T} T{ -Append single filter -T} -_ -T{ -\-add -T} T{ -Append 1 or more filters (same syntax as \-set) -T} -_ -T{ -\-pre -T} T{ -Prepend 1 or more filters (same syntax as \-set) -T} -_ -T{ -\-clr -T} T{ -Clear the option (remove all filters) -T} -_ -T{ -\-remove -T} T{ -Delete filter if present -T} -_ -T{ -\-del -T} T{ -Delete 1 or more filters by integer index or filter label (deprecated) -T} -_ -T{ -\-toggle -T} T{ -Append a filter, or remove if if it already exists -T} -_ -T{ -\-help -T} T{ -Pseudo operation that prints a help text to the terminal -T} -_ -.TE -.SS General -.sp -Without suffix, the operation used is normally \fB\-set\fP\&. -.sp -Although some operations allow specifying multiple items, using this is strongly -discouraged and deprecated, except for \fB\-set\fP\&. There is a chance that -operations like \fB\-add\fP and \fB\-pre\fP will work like \fB\-append\fP and accept a -single, unescaped item only (so the \fB,\fP separator will not be interpreted and -is passed on as part of the value). -.sp -Some options (like \fB\-\-sub\-file\fP, \fB\-\-audio\-file\fP, \fB\-\-glsl\-shader\fP) are -aliases for the proper option with \fB\-append\fP action. For example, -\fB\-\-sub\-file\fP is an alias for \fB\-\-sub\-files\-append\fP\&. -.sp -Options of this type can be changed at runtime using the \fBchange\-list\fP -command, which takes the suffix (without the \fB\-\fP) as separate operation -parameter. -.SH CONFIGURATION FILES -.SS Location and Syntax -.sp -You can put all of the options in configuration files which will be read every -time mpv is run. The system\-wide configuration file \(aqmpv.conf\(aq is in your -configuration directory (e.g. \fB/etc/mpv\fP or \fB/usr/local/etc/mpv\fP), the -user\-specific one is \fB~/.config/mpv/mpv.conf\fP\&. For details and platform -specifics (in particular Windows paths) see the \fI\%FILES\fP section. -.sp -User\-specific options override system\-wide options and options given on the -command line override either. The syntax of the configuration files is -\fBoption=value\fP\&. Everything after a \fI#\fP is considered a comment. Options -that work without values can be enabled by setting them to \fIyes\fP and disabled by -setting them to \fIno\fP\&.

The shell is not involved here, -but option values still need to be quoted as a whole if it contains certain -characters like spaces. A config entry can be quoted with \fB"\fP, -as well as with the fixed\-length syntax (\fB%n%\fP) mentioned before. This is like -passing the exact contents of the quoted string as command line option. C\-style -escapes are currently _not_ interpreted on this level, although some options do -this manually. (This is a mess and should probably be changed at some point.) -.SS Putting Command Line Options into the Configuration File -.sp -Almost all command line options can be put into the configuration file.

If you wish to have a -configuration file for a file called \(aqvideo.avi\(aq, create a file named -\(aqvideo.avi.conf\(aq with the file\-specific options in it and put it in -\fB~/.config/mpv/\fP\&. You can also put the configuration file in the same directory -as the file to be played. Both require you to set the \fB\-\-use\-filedir\-conf\fP -option (either on the command line or in your global config file). If a -file\-specific configuration file is found in the same directory, no -file\-specific configuration is loaded from \fB~/.config/mpv\fP\&. In addition, the -\fB\-\-use\-filedir\-conf\fP option enables directory\-specific configuration files. -For this, mpv first tries to load a mpv.conf from the same directory -as the file played and then tries to load any file\-specific configuration. -.SS Profiles -.sp -To ease working with different configurations, profiles can be defined in the -configuration files. A profile starts with its name in square brackets, -e.g. \fB[my\-profile]\fP\&. All following options will be part of the profile. A -description (shown by \fB\-\-profile=help\fP) can be defined with the -\fBprofile\-desc\fP option. To end the profile, start another one or use the -profile name \fBdefault\fP to continue with normal options. -.sp -You can list profiles with \fB\-\-profile=help\fP, and show the contents of a -profile with \fB\-\-show\-profile=<name>\fP (replace \fB<name>\fP with the profile -name). You can apply profiles on start with the \fB\-\-profile=<name>\fP option, -or at runtime with the \fBapply\-profile <name>\fP command. -.INDENT 0.0 -.INDENT 3.5 -.IP "Example mpv config file with profiles" -.INDENT 0.0 -.INDENT 3.5 -.sp -.nf -.ft C -# normal top\-level option -fullscreen=yes - -# a profile that can be enabled with \-\-profile=big\-cache -[big\-cache] -cache=yes -demuxer\-max\-bytes=123400KiB -demuxer\-readahead\-secs=20 - -[slow] -profile\-desc="some profile name" -# reference a builtin profile -profile=gpu\-hq - -[fast] -vo=vdpau - -# using a profile again extends it -[slow] -framedrop=no -# you can also include other profiles -profile=big\-cache -.ft P -.fi -.UNINDENT -.UNINDENT -.UNINDENT -.UNINDENT -.SS Runtime profiles -.sp -Profiles can be set at runtime with \fBapply\-profile\fP command. Since this -operation is "destructive" (every item in a profile is simply set as an -option, overwriting the previous value), you can\(aqt just enable and disable -profiles again. -.sp -As a partial remedy, there is a way to make profiles save old option values -before overwriting them with the profile values, and then restoring the old -values at a later point using \fBapply\-profile <profile\-name> restore\fP\&. -.sp -This can be enabled with the \fBprofile\-restore\fP option, which takes one of -the following options: -.INDENT 0.0 -.INDENT 3.5 -.INDENT 0.0 -.TP -.B \fBdefault\fP -Does nothing, and nothing can be restored (default). -.TP -.B \fBcopy\fP -When applying a profile, copy the old values of all profile options to a -backup before setting them from the profile. These options are reset to -their old values using the backup when restoring. -.sp -Every profile has its own list of backed up values. If the backup -already exists (e.g. if \fBapply\-profile name\fP was called more than -once in a row), the existing backup is no changed. The restore operation -will remove the backup. -.sp -It\(aqs important to know that restoring does not "undo" setting an option, -but simply copies the old option value. Consider for example \fBvf\-add\fP, -appends an entry to \fBvf\fP\&. This mechanism will simply copy the entire -\fBvf\fP list, and does _not_ execute the inverse of \fBvf\-add\fP (that -would be \fBvf\-remove\fP) on restoring. -.sp -Note that if a profile contains recursive profiles (via the \fBprofile\fP -option), the options in these recursive profiles are treated as if they -were part of this profile. The referenced profile\(aqs backup list is not -used when creating or using the backup. Restoring a profile does not -restore referenced profiles, only the options of referenced profiles (as -if they were part of the main profile). -.TP -.B \fBcopy\-equal\fP -Similar to \fBcopy\fP, but restore an option only if it has the same value -as the value effectively set by the profile. This tries to deal with -the situation when the user does not want the option to be reset after -interactively changing it. -.UNINDENT -.UNINDENT -.UNINDENT -.INDENT 0.0 -.INDENT 3.5 -.IP "Example" -.INDENT 0.0 -.INDENT 3.5 -.sp -.nf -.ft C -[something] -profile\-restore=copy\-equal -vf\-add=rotate=90 -.ft P -.fi -.UNINDENT -.UNINDENT -.sp -Then running these commands will result in behavior as commented: -.INDENT 0.0 -.INDENT 3.5 -.sp -.nf -.ft C -set vf vflip -apply\-profile something -vf\-add=hflip -apply\-profile something -# vf == vflip,rotate=90,hflip,rotate=90 -apply\-profile something restore -# vf == vflip -.ft P -.fi -.UNINDENT -.UNINDENT -.UNINDENT -.UNINDENT -.SS Conditional auto profiles -.sp -Profiles which have the \fBprofile\-cond\fP option set are applied automatically -if the associated condition matches (unless auto profiles are disabled). The -option takes a string, which is interpreted as Lua condition. If evaluating the -expression returns true, the profile is applied, if it returns false, it is -ignored. This Lua code execution is not sandboxed. -.sp -Any variables in condition expressions can reference properties. If an -identifier is not already defined by Lua or mpv, it is interpreted as property. -For example, \fBpause\fP would return the current pause status. You cannot -reference properties with \fB\-\fP this way since that would denote a subtraction, -but if the variable name contains any \fB_\fP characters, they are turned into -\fB\-\fP\&. For example, \fBplayback_time\fP would return the property -\fBplayback\-time\fP\&. -.sp -A more robust way to access properties is using \fBp.property_name\fP or -\fBget("property\-name", default_value)\fP\&. The automatic variable to property -magic will break if a new identifier with the same name is introduced (for -example, if a function named \fBpause()\fP were added, \fBpause\fP would return a -function value instead of the value of the \fBpause\fP property). -.sp -Note that if a property is not available, it will return \fBnil\fP, which can -cause errors if used in expressions. These are logged in verbose mode, and the -expression is considered to be false. -.sp -Whenever a property referenced by a profile condition changes, the condition -is re\-evaluated. If the return value of the condition changes from false or -error to true, the profile is applied. -.sp -This mechanism tries to "unapply" profiles once the condition changes from true -to false. If you want to use this, you need to set \fBprofile\-restore\fP for the -profile. Another possibility it to create another profile with an inverse -condition to undo the other profile. -.sp -Recursive profiles can be used. But it is discouraged to reference other -conditional profiles in a conditional profile, since this can lead to tricky -and unintuitive behavior. -.INDENT 0.0 -.INDENT 3.5 -.IP "Example" -.sp -Make only HD video look funny: -.INDENT 0.0 -.INDENT 3.5 -.sp -.nf -.ft C -[something] -profile\-desc=HD video sucks -profile\-cond=width >= 1280 -hue=\-50 -.ft P -.fi -.UNINDENT -.UNINDENT -.sp -If you want the profile to be reverted if the condition goes to false again, -you can set \fBprofile\-restore\fP: -.INDENT 0.0 -.INDENT 3.5 -.sp -.nf -.ft C -[something] -profile\-desc=Mess up video when entering fullscreen -profile\-cond=fullscreen -profile\-restore=copy -vf\-add=rotate=90 -.ft P -.fi -.UNINDENT -.UNINDENT -.sp -This appends the \fBrotate\fP filter to the video filter chain when entering -fullscreen.

None of these -problems exist on systems like Windows or macOS. -.SS Disabling Screensaver -.sp -By default, mpv tries to disable the OS screensaver during playback (only if -a VO using the OS GUI API is active). \fB\-\-stop\-screensaver=no\fP disables this. -.sp -A common problem is that Linux desktop environments ignore the standard -screensaver APIs on which mpv relies. In particular, mpv uses the Screen Saver -extension (XSS) on X11, and the idle\-inhibit on Wayland. -.sp -GNOME is one of the worst offenders, and ignores even the now widely supported -idle\-inhibit protocol. (This is either due to a combination of malice and -incompetence, but since implementing this protocol would only take a few lines -of code, it is most likely the former. You will also notice how GNOME advocates -react offended whenever their sabotage is pointed out, which indicates either -hypocrisy, or even worse ignorance.) -.sp -Such incompatible desktop environments (i.e. which ignore standards) typically -require using a DBus API. This is ridiculous in several ways. The immediate -practical problem is that it would require adding a quite unwieldy dependency -for a DBus library, somehow integrating its mainloop into mpv, and other -generally unacceptable things. -.sp -However, since mpv does not officially support GNOME, this is not much of a -problem. If you are one of those miserable users who want to use mpv on GNOME, -report a bug on the GNOME issue tracker: -\fI\%https://gitlab.gnome.org/groups/GNOME/\-/issues\fP -.sp -Alternatively, you may be able to write a Lua script that calls the -\fBxdg\-screensaver\fP command line program. (By the way, this a command line -program is an utterly horrible kludge that tries to identify your DE, and then -tries to send the correct DBus command via a DBus CLI tool.) If you find the -idea of having to write a script just so your screensaver doesn\(aqt kick in -ridiculous, do not use GNOME, or use GNOME video software instead of mpv (good -luck). -.sp -Before mpv 0.33.0, the X11 backend ran \fBxdg\-screensaver reset\fP in 10 second -intervals when not paused.

Also, the -behavior tends to change around with each mpv release. -.sp -The track selection properties will return the option value outside of -playback (as expected), but during playback, the affective track -selection is returned. For example, with \fB\-\-aid=auto\fP, the \fBaid\fP -property will suddenly return \fB2\fP after playback initialization -(assuming the file has at least 2 audio tracks, and the second is the -default). -.sp -At mpv 0.32.0 (and some releases before), if you passed a track value -for which a corresponding track didn\(aqt exist (e.g. \fB\-\-aid=2\fP and there -was only 1 audio track), the \fBaid\fP property returned \fBno\fP\&. However if -another audio track was added during playback, and you tried to set the -\fBaid\fP property to \fB2\fP, nothing happened, because the \fBaid\fP option -still had the value \fB2\fP, and writing the same value has no effect. -.sp -With mpv 0.33.0, the behavior was changed. Now track selection options -are reset to \fBauto\fP at playback initialization, if the option had -tries to select a track that does not exist.

The consequence is that unlike -before mpv 0.33.0, the user\(aqs track selection parameters are clobbered -in certain situations. -.sp -Also since mpv 0.33.0, trying to select a track by number will strictly -select this track.

The new behavior is more consistent. -.sp -Setting a track selection property at runtime, and then playing a new -file might reset the track selection to defaults, if the fingerprint -of the track list of the new file is different. -.sp -Be aware of tricky combinations of all of all of the above: for example, -\fBmpv \-\-aid=2 file_with_2_audio_tracks.mkv file_with_1_audio_track.mkv\fP -would first play the correct track, and the second file without audio. -If you then go back the first file, its first audio track will be played, -and the second file is played with audio. If you do the same thing again -but instead of using \fB\-\-aid=2\fP you run \fBset aid 2\fP while the file is -playing, then changing to the second file will play its audio track. -This is because runtime selection enables the fingerprint heuristic. -.sp -Most likely this is not the end. -.UNINDENT -.UNINDENT -.TP -.B \fB\-\-sid=<ID|auto|no>\fP -Display the subtitle stream specified by \fB<ID>\fP\&. \fBauto\fP selects -the default, \fBno\fP disables subtitles. -.sp -\fB\-\-sub\fP is an alias for \fB\-\-sid\fP\&. -.sp -\fB\-\-sid=no\fP or \fB\-\-sub=no\fP or \fB\-\-no\-sub\fP disables subtitle decoding. -(The latter variant does not work with the client API.) -.TP -.B \fB\-\-vid=<ID|auto|no>\fP -Select video channel. \fBauto\fP selects the default, \fBno\fP disables video. -.sp -\fB\-\-video\fP is an alias for \fB\-\-vid\fP\&. -.sp -\fB\-\-vid=no\fP or \fB\-\-video=no\fP or \fB\-\-no\-video\fP disables video playback. -(The latter variant does not work with the client API.) -.sp -If video is disabled, mpv will try to download the audio only if media is -streamed with youtube\-dl, because it saves bandwidth.

As long as no packet has -a timestamp difference higher than the readahead amount relative to the -last packet returned to the decoder, the demuxer keeps reading. -.sp -Note that enabling the cache (such as \fB\-\-cache=yes\fP, or if the input -is considered a network stream, and \fB\-\-cache=auto\fP is used), this option -is mostly ignored. (\fB\-\-cache\-secs\fP will override this. Technically, the -maximum of both options is used.) -.sp -The main purpose of this option is to limit the readhead for local playback, -since a large readahead value is not overly useful in this case. -.sp -(This value tends to be fuzzy, because many file formats don\(aqt store linear -timestamps.) -.TP -.B \fB\-\-prefetch\-playlist=<yes|no>\fP -Prefetch next playlist entry while playback of the current entry is ending -(default: no). -.sp -This does not prefill the cache with the video data of the next URL. -Prefetching video data is supported only for the current playlist entry, -and depends on the demuxer cache settings (on by default). This merely -opens the URL of the next playlist entry as soon the current URL is fully -read. -.sp -This does \fBnot\fP work with URLs resolved by the \fByoutube\-dl\fP wrapper, -and it won\(aqt. -.sp -This can give subtly wrong results if per\-file options are used, or if -options are changed in the time window between prefetching start and next -file played. -.sp -This can occasionally make wrong prefetching decisions. For example, it -can\(aqt predict whether you go backwards in the playlist, and assumes you -won\(aqt edit the playlist. -.sp -Highly experimental. -.TP -.B \fB\-\-force\-seekable=<yes|no>\fP -If the player thinks that the media is not seekable (e.g. playing from a -pipe, or it\(aqs an http stream with a server that doesn\(aqt support range -requests), seeking will be disabled.

Only once this -is done, playback starts. This intentionally happens before the initial -seek triggered with \fB\-\-start\fP\&. This does not change any runtime behavior -after the initial caching. This option is useless if the file cannot be -cached completely. -.TP -.B \fB\-\-rar\-list\-all\-volumes=<yes|no>\fP -When opening multi\-volume rar files, open all volumes to create a full list -of contained files (default: no). If disabled, only the archive entries -whose headers are located within the first volume are listed (and thus -played when opening a .rar file with mpv). Doing so speeds up opening, and -the typical idiotic use\-case of playing uncompressed multi\-volume rar files -that contain a single media file is made faster. -.sp -Opening is still slow, because for unknown, idiotic, and unnecessary reasons -libarchive opens all volumes anyway when playing the main file, even though -mpv iterated no archive entries yet. -.UNINDENT -.SS Input -.INDENT 0.0 -.TP -.B \fB\-\-native\-keyrepeat\fP -Use system settings for keyrepeat delay and rate, instead of -\fB\-\-input\-ar\-delay\fP and \fB\-\-input\-ar\-rate\fP\&.

These are bindings which config -files like \fBinput.conf\fP can override. It currently affects the builtin key -bindings, and keys which scripts bind using \fBmp.add_key_binding\fP (but not -\fBmp.add_forced_key_binding\fP because this overrides \fBinput.conf\fP). -.TP -.B \fB\-\-no\-input\-builtin\-bindings\fP -Disable loading of built\-in key bindings during start\-up.

If it -is too small, some events may be lost. The main disadvantage of setting it -to a very large value is that if you hold down a key triggering some -particularly slow command then the player may be unresponsive while it -processes all the queued commands. -.TP -.B \fB\-\-input\-test\fP -Input test mode. Instead of executing commands on key presses, mpv -will show the keys and the bound commands on the OSD.

Generally useful for -embedding only. -.sp -On X11, a sub\-window with input enabled grabs all keyboard input as long -as it is 1. a child of a focused window, and 2. the mouse is inside of -the sub\-window. It can steal away all keyboard input from the -application embedding the mpv window, and on the other hand, the mpv -window will receive no input if the mouse is outside of the mpv window, -even though mpv has focus. Modern toolkits work around this weird X11 -behavior, but naively embedding foreign windows breaks it. -.sp -The only way to handle this reasonably is using the XEmbed protocol, which -was designed to solve these problems.

There are currently two types of blocks, HOOKs and -TEXTUREs. -.sp -A \fBTEXTURE\fP block can set the following options: -.INDENT 7.0 -.TP -.B TEXTURE <name> (required) -The name of this texture. Hooks can then bind the texture under this -name using BIND. This must be the first option of the texture block. -.TP -.B SIZE <width> [<height>] [<depth>] (required) -The dimensions of the texture. The height and depth are optional. The -type of texture (1D, 2D or 3D) depends on the number of components -specified. -.TP -.B FORMAT <name> (required) -The texture format for the samples. Supported texture formats are listed -in debug logging when the \fBgpu\fP VO is initialized (look for -\fBTexture formats:\fP). Usually, this follows OpenGL naming conventions. -For example, \fBrgb16\fP provides 3 channels with normalized 16 bit -components. One oddity are float formats: for example, \fBrgba16f\fP has -16 bit internal precision, but the texture data is provided as 32 bit -floats, and the driver converts the data on texture upload. -.sp -Although format names follow a common naming convention, not all of them -are available on all hardware, drivers, GL versions, and so on. -.TP -.B FILTER <LINEAR|NEAREST> -The min/magnification filter used when sampling from this texture. -.TP -.B BORDER <CLAMP|REPEAT|MIRROR> -The border wrapping mode used when sampling from this texture. -.UNINDENT -.sp -Following the metadata is a string of bytes in hexadecimal notation that -define the raw texture data, corresponding to the format specified by -\fIFORMAT\fP, on a single line with no extra whitespace. -.sp -A \fBHOOK\fP block can set the following options: -.INDENT 7.0 -.TP -.B HOOK <name> (required) -The texture which to hook into. May occur multiple times within a -metadata block, up to a predetermined limit. See below for a list of -hookable textures. -.TP -.B DESC <title> -User\-friendly description of the pass. This is the name used when -representing this shader in the list of passes for property -\fIvo\-passes\fP\&. -.TP -.B BIND <name> -Loads a texture (either coming from mpv or from a \fBTEXTURE\fP block) -and makes it available to the pass. When binding textures from mpv, -this will also set up macros to facilitate accessing it properly. See -below for a list. By default, no textures are bound. The special name -HOOKED can be used to refer to the texture that triggered this pass. -.TP -.B SAVE <name> -Gives the name of the texture to save the result of this pass into. By -default, this is set to the special name HOOKED which has the effect of -overwriting the hooked texture. -.TP -.B WIDTH <szexpr>, HEIGHT <szexpr> -Specifies the size of the resulting texture for this pass. \fBszexpr\fP -refers to an expression in RPN (reverse polish notation), using the -operators + \- * / > < !, floating point literals, and references to -sizes of existing texture (such as MAIN.width or CHROMA.height), -OUTPUT, or NATIVE_CROPPED (size of an input texture cropped after -pan\-and\-scan, video\-align\-x/y, video\-pan\-x/y, etc. and possibly -prescaled). By default, these are set to HOOKED.w and HOOKED.h, -espectively. -.TP -.B WHEN <szexpr> -Specifies a condition that needs to be true (non\-zero) for the shader -stage to be evaluated. If it fails, it will silently be omitted. (Note -that a shader stage like this which has a dependency on an optional -hook point can still cause that hook point to be saved, which has some -minor overhead) -.TP -.B OFFSET <ox oy | ALIGN> -Indicates a pixel shift (offset) introduced by this pass. These pixel -offsets will be accumulated and corrected during the next scaling pass -(\fBcscale\fP or \fBscale\fP). The default values are 0 0 which correspond -to no shift. Note that offsets are ignored when not overwriting the -hooked texture. -.sp -A special value of \fBALIGN\fP will attempt to fix existing offset of -HOOKED by align it with reference. It requires HOOKED to be resizable -(see below). It works transparently with fragment shader. For compute -shader, the predefined \fBtexmap\fP macro is required to handle coordinate -mapping. -.TP -.B COMPONENTS <n> -Specifies how many components of this pass\(aqs output are relevant and -should be stored in the texture, up to 4 (rgba). By default, this value -is equal to the number of components in HOOKED. -.TP -.B COMPUTE <bw> <bh> [<tw> <th>] -Specifies that this shader should be treated as a compute shader, with -the block size bw and bh. The compute shader will be dispatched with -however many blocks are necessary to completely tile over the output. -Within each block, there will be tw*th threads, forming a single work -group. In other words: tw and th specify the work group size, which can -be different from the block size. So for example, a compute shader with -bw, bh = 32 and tw, th = 8 running on a 500x500 texture would dispatch -16x16 blocks (rounded up), each with 8x8 threads. -.sp -Compute shaders in mpv are treated a bit different from fragment -shaders. Instead of defining a \fBvec4 hook\fP that produces an output -sample, you directly define \fBvoid hook\fP which writes to a fixed -writeonly image unit named \fBout_image\fP (this is bound by mpv) using -\fIimageStore\fP\&. To help translate texture coordinates in the absence of -vertices, mpv provides a special function \fBNAME_map(id)\fP to map from -the texel space of the output image to the texture coordinates for all -bound textures. In particular, \fBNAME_pos\fP is equivalent to -\fBNAME_map(gl_GlobalInvocationID)\fP, although using this only really -makes sense if (tw,th) == (bw,bh). -.UNINDENT -.sp -Each bound mpv texture (via \fBBIND\fP) will make available the following -definitions to that shader pass, where NAME is the name of the bound -texture: -.INDENT 7.0 -.TP -.B vec4 NAME_tex(vec2 pos) -The sampling function to use to access the texture at a certain spot -(in texture coordinate space, range [0,1]). This takes care of any -necessary normalization conversions. -.TP -.B vec4 NAME_texOff(vec2 offset) -Sample the texture at a certain offset in pixels. This works like -NAME_tex but additionally takes care of necessary rotations, so that -sampling at e.g. vec2(\-1,0) is always one pixel to the left. -.TP -.B vec2 NAME_pos -The local texture coordinate of that texture, range [0,1]. -.TP -.B vec2 NAME_size -The (rotated) size in pixels of the texture. -.TP -.B mat2 NAME_rot -The rotation matrix associated with this texture. (Rotates pixel space -to texture coordinates) -.TP -.B vec2 NAME_pt -The (unrotated) size of a single pixel, range [0,1]. -.TP -.B float NAME_mul -The coefficient that needs to be multiplied into the texture contents -in order to normalize it to the range [0,1]. -.TP -.B sampler NAME_raw -The raw bound texture itself. The use of this should be avoided unless -absolutely necessary. -.UNINDENT -.sp -Normally, users should use either NAME_tex or NAME_texOff to read from the -texture. For some shaders however , it can be better for performance to do -custom sampling from NAME_raw, in which case care needs to be taken to -respect NAME_mul and NAME_rot. -.sp -In addition to these parameters, the following uniforms are also globally -available: -.INDENT 7.0 -.TP -.B float random -A random number in the range [0\-1], different per frame. -.TP -.B int frame -A simple count of frames rendered, increases by one per frame and never -resets (regardless of seeks). -.TP -.B vec2 input_size -The size in pixels of the input image (possibly cropped and prescaled). -.TP -.B vec2 target_size -The size in pixels of the visible part of the scaled (and possibly -cropped) image. -.TP -.B vec2 tex_offset -Texture offset introduced by user shaders or options like panscan, video\-align\-x/y, video\-pan\-x/y. -.UNINDENT -.sp -Internally, vo_gpu may generate any number of the following textures. -Whenever a texture is rendered and saved by vo_gpu, all of the passes -that have hooked into it will run, in the order they were added by the -user. This is a list of the legal hook points: -.INDENT 7.0 -.TP -.B RGB, LUMA, CHROMA, ALPHA, XYZ (resizable) -Source planes (raw).

The interpretation of this brightness depends on the configured -\fB\-\-target\-trc\fP\&. In all cases, it imposes a limit on the signal values -that will be sent to the display. If the source exceeds this brightness -level, a tone mapping filter will be inserted. For HLG, it has the -additional effect of parametrizing the inverse OOTF, in order to get -colorimetrically consistent results with the mastering display. For SDR, or -when using an ICC (profile (\fB\-\-icc\-profile\fP), setting this to a value -above 203 essentially causes the display to be treated as if it were an HDR -display in disguise. (See the note below) -.sp -In \fBauto\fP mode (the default), the chosen peak is an appropriate value -based on the TRC in use. For SDR curves, it uses 203.

The one time it \fIis\fP -useful is if you want to calibrate a HDR display using traditional -transfer functions and calibration equipment. In such cases, you can -set your HDR display to a high brightness such as 800 cd/m^2, and then -calibrate it to a standard curve like gamma2.8. Setting this value to -800 would then instruct mpv to essentially treat it as an HDR display -with the given peak. This may be a good alternative in environments -where PQ or HLG input to the display is not possible, and makes it -possible to use HDR displays with mpv regardless of operating system -support for HDMI HDR metadata. -.sp -In such a configuration, we highly recommend setting \fB\-\-tone\-mapping\fP -to \fBmobius\fP or even \fBclip\fP\&. -.UNINDENT -.UNINDENT -.TP -.B \fB\-\-tone\-mapping=<value>\fP -Specifies the algorithm used for tone\-mapping images onto the target -display.

Use this when you care about -perfect color accuracy for in\-range values at the cost of completely -distorting out\-of\-range values. Not generally recommended. -.TP -.B mobius -Generalization of Reinhard to a Möbius transform with linear section. -Smoothly maps out\-of\-range values while retaining contrast and colors -for in\-range material as much as possible. Use this when you care about -color accuracy more than detail preservation. This is somewhere in -between \fBclip\fP and \fBreinhard\fP, depending on the value of -\fB\-\-tone\-mapping\-param\fP\&. -.TP -.B reinhard -Reinhard tone mapping algorithm. Very simple continuous curve. -Preserves overall image brightness but uses nonlinear contrast, which -results in flattening of details and degradation in color accuracy. -.TP -.B hable -Similar to \fBreinhard\fP but preserves both dark and bright details -better (slightly sigmoidal), at the cost of slightly darkening / -desaturating everything. Developed by John Hable for use in video -games. Use this when you care about detail preservation more than -color/brightness accuracy. This is roughly equivalent to -\fB\-\-tone\-mapping=reinhard \-\-tone\-mapping\-param=0.24\fP\&. If possible, -you should also enable \fB\-\-hdr\-compute\-peak\fP for the best results. -.TP -.B bt.2390 -Perceptual tone mapping curve (EETF) specified in ITU\-R Report BT.2390. -This is the recommended curve to use for typical HDR\-mastered content. -(Default) -.TP -.B gamma -Fits a logarithmic transfer between the tone curves. -.TP -.B linear -Linearly stretches the entire reference gamut to (a linear multiple of) -the display. -.UNINDENT -.TP -.B \fB\-\-tone\-mapping\-param=<value>\fP -Set tone mapping parameters. By default, this is set to the special string -\fBdefault\fP, which maps to an algorithm\-specific default value. Ignored if -the tone mapping algorithm is not tunable. This affects the following tone -mapping algorithms: -.INDENT 7.0 -.TP -.B clip -Specifies an extra linear coefficient to multiply into the signal -before clipping. Defaults to 1.0. -.TP -.B mobius -Specifies the transition point from linear to mobius transform. Every -value below this point is guaranteed to be mapped 1:1. The higher the -value, the more accurate the result will be, at the cost of losing -bright details. Defaults to 0.3, which due to the steep initial slope -still preserves in\-range colors fairly accurately. -.TP -.B reinhard -Specifies the local contrast coefficient at the display peak. Defaults -to 0.5, which means that in\-gamut values will be about half as bright -as when clipping. -.TP -.B gamma -Specifies the exponent of the function. Defaults to 1.8. -.TP -.B linear -Specifies the scale factor to use while stretching. Defaults to 1.0. -.UNINDENT -.TP -.B \fB\-\-tone\-mapping\-max\-boost=<1.0..10.0>\fP -Upper limit for how much the tone mapping algorithm is allowed to boost -the average brightness by over\-exposing the image. The default value of 1.0 -allows no additional brightness boost. A value of 2.0 would allow -over\-exposing by a factor of 2, and so on. Raising this setting can help -reveal details that would otherwise be hidden in dark scenes, but raising -it too high will make dark scenes appear unnaturally bright. -.TP -.B \fB\-\-hdr\-compute\-peak=<auto|yes|no>\fP -Compute the HDR peak and frame average brightness per\-frame instead of -relying on tagged metadata. These values are averaged over local regions as -well as over several frames to prevent the value from jittering around too -much. This option basically gives you dynamic, per\-scene tone mapping. -Requires compute shaders, which is a fairly recent OpenGL feature, and will -probably also perform horribly on some drivers, so enable at your own risk. -The special value \fBauto\fP (default) will enable HDR peak computation -automatically if compute shaders and SSBOs are supported. -.TP -.B \fB\-\-hdr\-peak\-decay\-rate=<1.0..1000.0>\fP -The decay rate used for the HDR peak detection algorithm (default: 100.0). -This is only relevant when \fB\-\-hdr\-compute\-peak\fP is enabled. Higher values -make the peak decay more slowly, leading to more stable values at the cost -of more "eye adaptation"\-like effects (although this is mitigated somewhat -by \fB\-\-hdr\-scene\-threshold\fP). A value of 1.0 (the lowest possible) disables -all averaging, meaning each frame\(aqs value is used directly as measured, -but doing this is not recommended for "noisy" sources since it may lead -to excessive flicker. (In signal theory terms, this controls the time -constant "tau" of an IIR low pass filter) -.TP -.B \fB\-\-hdr\-scene\-threshold\-low=<0.0..100.0>\fP, \fB\-\-hdr\-scene\-threshold\-high=<0.0..100.0>\fP -The lower and upper thresholds (in dB) for a brightness difference -to be considered a scene change (default: 5.5 low, 10.0 high). This is only -relevant when \fB\-\-hdr\-compute\-peak\fP is enabled. Normally, small -fluctuations in the frame brightness are compensated for by the peak -averaging mechanism, but for large jumps in the brightness this can result -in the frame remaining too bright or too dark for up to several seconds, -depending on the value of \fB\-\-hdr\-peak\-decay\-rate\fP\&. To counteract this, -when the brightness between the running average and the current frame -exceeds the low threshold, mpv will make the averaging filter more -aggressive, up to the limit of the high threshold (at which point the -filter becomes instant). -.TP -.B \fB\-\-tone\-mapping\-desaturate=<0.0..1.0>\fP -Apply desaturation for highlights (default: 0.75). The parameter controls -the strength of the desaturation curve. A value of 0.0 completely disables -it, while a value of 1.0 means that overly bright colors will tend towards -white. (This is not always the case, especially not for highlights that are -near primary colors) -.sp -Values in between apply progressively more/less aggressive desaturation. -This setting helps prevent unnaturally oversaturated colors for -super\-highlights, by (smoothly) turning them into less saturated (per -channel tone mapped) colors instead. This makes images feel more natural, -at the cost of chromatic distortions for out\-of\-range colors. The default -value of 0.75 provides a good balance. Setting this to 0.0 preserves the -chromatic accuracy of the tone mapping process. -.TP -.B \fB\-\-tone\-mapping\-desaturate\-exponent=<0.0..20.0>\fP -This setting controls the exponent of the desaturation curve, which -controls how bright a color needs to be in order to start being -desaturated. The default of 1.5 provides a reasonable balance. Decreasing -this exponent makes the curve more aggressive. -.TP -.B \fB\-\-gamut\-warning\fP -If enabled, mpv will mark all clipped/out\-of\-gamut pixels that exceed a -given threshold (currently hard\-coded to 101%). The affected pixels will be -inverted to make them stand out. Note: This option applies after the -effects of all of mpv\(aqs color space transformation / tone mapping options, -so it\(aqs a good idea to combine this with \fB\-\-tone\-mapping=clip\fP and use -\fB\-\-target\-prim\fP to set the gamut to simulate. For example, -\fB\-\-target\-prim=bt.709\fP would make mpv highlight all pixels that exceed the -gamut of a standard gamut (sRGB) display. This option also does not work -well with ICC profiles, since the 3DLUTs are always generated against the -source color space and have chromatically\-accurate clipping built in. -.TP -.B \fB\-\-gamut\-clipping\fP -If enabled (default: yes), mpv will colorimetrically clip out\-of\-gamut -colors by desaturating them (preserving luma), rather than hard\-clipping -each component individually. This should make playback of wide gamut -content on typical (standard gamut) monitors look much more aesthetically -pleasing and less blown\-out. -.TP -.B \fB\-\-use\-embedded\-icc\-profile\fP -Load the embedded ICC profile contained in media files such as PNG images. -(Default: yes). Note that this option only works when also using a display -ICC profile (\fB\-\-icc\-profile\fP or \fB\-\-icc\-profile\-auto\fP), and also -requires LittleCMS 2 support. -.TP -.B \fB\-\-icc\-profile=<file>\fP -Load an ICC profile and use it to transform video RGB to screen output. -Needs LittleCMS 2 support compiled in. This option overrides the -\fB\-\-target\-prim\fP, \fB\-\-target\-trc\fP and \fB\-\-icc\-profile\-auto\fP options. -.TP -.B \fB\-\-icc\-profile\-auto\fP -Automatically select the ICC display profile currently specified by the -display settings of the operating system. -.sp -NOTE: On Windows, the default profile must be an ICC profile. WCS profiles -are not supported. -.sp -Applications using libmpv with the render API need to provide the ICC -profile via \fBMPV_RENDER_PARAM_ICC_PROFILE\fP\&. -.TP -.B \fB\-\-icc\-cache\-dir=<dirname>\fP -Store and load the 3D LUTs created from the ICC profile in this directory. -This can be used to speed up loading, since LittleCMS 2 can take a while to -create a 3D LUT. Note that these files contain uncompressed LUTs. Their -size depends on the \fB\-\-icc\-3dlut\-size\fP, and can be very big. -.sp -NOTE: This is not cleaned automatically, so old, unused cache files may -stick around indefinitely. -.TP -.B \fB\-\-icc\-intent=<value>\fP -Specifies the ICC intent used for the color transformation (when using -\fB\-\-icc\-profile\fP). -.INDENT 7.0 -.TP -.B 0 -perceptual -.TP -.B 1 -relative colorimetric (default) -.TP -.B 2 -saturation -.TP -.B 3 -absolute colorimetric -.UNINDENT -.TP -.B \fB\-\-icc\-3dlut\-size=<r>x<g>x<b>\fP -Size of the 3D LUT generated from the ICC profile in each dimension. -Default is 64x64x64. Sizes may range from 2 to 512. -.TP -.B \fB\-\-icc\-force\-contrast=<no|0\-1000000|inf>\fP -Override the target device\(aqs detected contrast ratio by a specific value. -This is detected automatically from the profile if possible, but for some -profiles it might be missing, causing the contrast to be assumed as -infinite. As a result, video may appear darker than intended. If this is -the case, setting this option might help. This only affects BT.1886 -content. The default of \fBno\fP means to use the profile values. The special -value \fBinf\fP causes the BT.1886 curve to be treated as a pure power gamma -2.4 function. -.TP -.B \fB\-\-blend\-subtitles=<yes|video|no>\fP -Blend subtitles directly onto upscaled video frames, before interpolation -and/or color management (default: no). Enabling this causes subtitles to be -affected by \fB\-\-icc\-profile\fP, \fB\-\-target\-prim\fP, \fB\-\-target\-trc\fP, -\fB\-\-interpolation\fP, \fB\-\-gamma\-factor\fP and \fB\-\-glsl\-shaders\fP\&. It also -increases subtitle performance when using \fB\-\-interpolation\fP\&. -.sp -The downside of enabling this is that it restricts subtitles to the visible -portion of the video, so you can\(aqt have subtitles exist in the black -margins below a video (for example). -.sp -If \fBvideo\fP is selected, the behavior is similar to \fByes\fP, but subs are -drawn at the video\(aqs native resolution, and scaled along with the video. -.sp -\fBWARNING:\fP -.INDENT 7.0 -.INDENT 3.5 -This changes the way subtitle colors are handled. Normally, -subtitle colors are assumed to be in sRGB and color managed as -such. Enabling this makes them treated as being in the video\(aqs -color space instead. This is good if you want things like -softsubbed ASS signs to match the video colors, but may cause -SRT subtitles or similar to look slightly off. -.UNINDENT -.UNINDENT -.TP -.B \fB\-\-alpha=<blend\-tiles|blend|yes|no>\fP -Decides what to do if the input has an alpha component. -.INDENT 7.0 -.TP -.B blend\-tiles -Blend the frame against a 16x16 gray/white tiles background (default). -.TP -.B blend -Blend the frame against the background color (\fB\-\-background\fP, normally -black). -.TP -.B yes -Try to create a framebuffer with alpha component. This only makes sense -if the video contains alpha information (which is extremely rare) or if -you make the background color transparent. May not be supported on all -platforms. If alpha framebuffers are unavailable, it silently falls -back on a normal framebuffer. Note that if you set the \fB\-\-fbo\-format\fP -option to a non\-default value, a format with alpha must be specified, -or this won\(aqt work. Whether this really works depends on the windowing -system and desktop environment. -.TP -.B no -Ignore alpha component. -.UNINDENT -.TP -.B \fB\-\-opengl\-rectangle\-textures\fP -Force use of rectangle textures (default: no). Normally this shouldn\(aqt have -any advantages over normal textures. Note that hardware decoding overrides -this flag. Could be removed any time. -.TP -.B \fB\-\-background=<color>\fP -Color used to draw parts of the mpv window not covered by video. See the -\fB\-\-sub\-color\fP option for how colors are defined. -.TP -.B \fB\-\-gpu\-tex\-pad\-x\fP, \fB\-\-gpu\-tex\-pad\-y\fP -Enlarge the video source textures by this many pixels. For debugging only -(normally textures are sized exactly, but due to hardware decoding interop -we may have to deal with additional padding, which can be tested with these -options). Could be removed any time. -.TP -.B \fB\-\-opengl\-early\-flush=<yes|no|auto>\fP -Call \fBglFlush()\fP after rendering a frame and before attempting to display -it (default: auto). Can fix stuttering in some cases, in other cases -probably causes it. The \fBauto\fP mode will call \fBglFlush()\fP only if -the renderer is going to wait for a while after rendering, instead of -flipping GL front and backbuffers immediately (i.e. it doesn\(aqt call it -in display\-sync mode). -.sp -On macOS this is always deactivated because it only causes performance -problems and other regressions. -.TP -.B \fB\-\-gpu\-dumb\-mode=<yes|no|auto>\fP -This mode is extremely restricted, and will disable most extended -features. That includes high quality scalers and custom shaders! -.sp -It is intended for hardware that does not support FBOs (including GLES, -which supports it insufficiently), or to get some more performance out of -bad or old hardware. -.sp -This mode is forced automatically if needed, and this option is mostly -useful for debugging. The default of \fBauto\fP will enable it automatically -if nothing uses features which require FBOs. -.sp -This option might be silently removed in the future. -.TP -.B \fB\-\-gpu\-shader\-cache\-dir=<dirname>\fP -Store and load compiled GLSL shaders in this directory. Normally, shader -compilation is very fast, so this is usually not needed. It mostly matters -for GPU APIs that require internally recompiling shaders to other languages, -for example anything based on ANGLE or Vulkan. Enabling this can improve -startup performance on these platforms. -.sp -NOTE: This is not cleaned automatically, so old, unused cache files may -stick around indefinitely. -.UNINDENT -.SS Miscellaneous -.INDENT 0.0 -.TP -.B \fB\-\-display\-tags=tag1,tags2,...\fP -Set the list of tags that should be displayed on the terminal. Tags that -are in the list, but are not present in the played file, will not be shown. -If a value ends with \fB*\fP, all tags are matched by prefix (though there -is no general globbing). Just passing \fB*\fP essentially filtering. -.sp -The default includes a common list of tags, call mpv with \fB\-\-list\-options\fP -to see it. -.sp -This is a string list option. See \fI\%List Options\fP for details. -.TP -.B \fB\-\-mc=<seconds/frame>\fP -Maximum A\-V sync correction per frame (in seconds) -.TP -.B \fB\-\-autosync=<factor>\fP -Gradually adjusts the A/V sync based on audio delay measurements. -Specifying \fB\-\-autosync=0\fP, the default, will cause frame timing to be -based entirely on audio delay measurements. Specifying \fB\-\-autosync=1\fP -will do the same, but will subtly change the A/V correction algorithm. An -uneven video framerate in a video which plays fine with \fB\-\-no\-audio\fP can -often be helped by setting this to an integer value greater than 1. The -higher the value, the closer the timing will be to \fB\-\-no\-audio\fP\&. Try -\fB\-\-autosync=30\fP to smooth out problems with sound drivers which do not -implement a perfect audio delay measurement. With this value, if large A/V -sync offsets occur, they will only take about 1 or 2 seconds to settle -out. This delay in reaction time to sudden A/V offsets should be the only -side effect of turning this option on, for all sound drivers. -.TP -.B \fB\-\-video\-timing\-offset=<seconds>\fP -Control how long before video display target time the frame should be -rendered (default: 0.050). If a video frame should be displayed at a -certain time, the VO will start rendering the frame earlier, and then will -perform a blocking wait until the display time, and only then "swap" the -frame to display. The rendering cannot start before the previous frame is -displayed, so this value is implicitly limited by the video framerate. With -normal video frame rates, the default value will ensure that rendering is -always immediately started after the previous frame was displayed. On the -other hand, setting a too high value can reduce responsiveness with low -FPS value. -.sp -For client API users using the render API (or the deprecated \fBopengl\-cb\fP -API), this option is interesting, because you can stop the render API -from limiting your FPS (see \fBmpv_render_context_render()\fP documentation). -.sp -This applies only to audio timing modes (e.g. \fB\-\-video\-sync=audio\fP). In -other modes (\fB\-\-video\-sync=display\-...\fP), video timing relies on vsync -blocking, and this option is not used. -.TP -.B \fB\-\-video\-sync=<audio|...>\fP -How the player synchronizes audio and video. -.sp -If you use this option, you usually want to set it to \fBdisplay\-resample\fP -to enable a timing mode that tries to not skip or repeat frames when for -example playing 24fps video on a 24Hz screen. -.sp -The modes starting with \fBdisplay\-\fP try to output video frames completely -synchronously to the display, using the detected display vertical refresh -rate as a hint how fast frames will be displayed on average. These modes -change video speed slightly to match the display. See \fB\-\-video\-sync\-...\fP -options for fine tuning. The robustness of this mode is further reduced by -making a some idealized assumptions, which may not always apply in reality. -Behavior can depend on the VO and the system\(aqs video and audio drivers. -Media files must use constant framerate. Section\-wise VFR might work as well -with some container formats (but not e.g. mkv). -.sp -Under some circumstances, the player automatically reverts to \fBaudio\fP mode -for some time or permanently. This can happen on very low framerate video, -or if the framerate cannot be detected. -.sp -Also in display\-sync modes it can happen that interruptions to video -playback (such as toggling fullscreen mode, or simply resizing the window) -will skip the video frames that should have been displayed, while \fBaudio\fP -mode will display them after the renderer has resumed (typically resulting -in a short A/V desync and the video "catching up"). -.sp -Before mpv 0.30.0, there was a fallback to \fBaudio\fP mode on severe A/V -desync. This was changed for the sake of not sporadically stopping. Now, -\fBdisplay\-desync\fP does what it promises and may desync with audio by an -arbitrary amount, until it is manually fixed with a seek. -.sp -These modes also require a vsync blocked presentation mode. For OpenGL, this -translates to \fB\-\-opengl\-swapinterval=1\fP\&. For Vulkan, it translates to -\fB\-\-vulkan\-swap\-mode=fifo\fP (or \fBfifo\-relaxed\fP). -.sp -The modes with \fBdesync\fP in their names do not attempt to keep audio/video -in sync. They will slowly (or quickly) desync, until e.g. the next seek -happens. These modes are meant for testing, not serious use. -.INDENT 7.0 -.TP -.B audio -Time video frames to audio. This is the most robust -mode, because the player doesn\(aqt have to assume anything -about how the display behaves. The disadvantage is that -it can lead to occasional frame drops or repeats. If -audio is disabled, this uses the system clock. This is -the default mode. -.TP -.B display\-resample -Resample audio to match the video. This mode will also -try to adjust audio speed to compensate for other drift. -(This means it will play the audio at a different speed -every once in a while to reduce the A/V difference.) -.TP -.B display\-resample\-vdrop -Resample audio to match the video. Drop video -frames to compensate for drift. -.TP -.B display\-resample\-desync -Like the previous mode, but no A/V compensation. -.TP -.B display\-vdrop -Drop or repeat video frames to compensate desyncing -video. (Although it should have the same effects as -\fBaudio\fP, the implementation is very different.) -.TP -.B display\-adrop -Drop or repeat audio data to compensate desyncing -video. This mode will cause severe audio artifacts if -the real monitor refresh rate is too different from -the reported or forced rate. Since mpv 0.33.0, this -acts on entire audio frames, instead of single samples. -.TP -.B display\-desync -Sync video to display, and let audio play on its own. -.TP -.B desync -Sync video according to system clock, and let audio play -on its own. -.UNINDENT -.TP -.B \fB\-\-video\-sync\-max\-factor=<value>\fP -Maximum multiple for which to try to fit the video\(aqs FPS to the display\(aqs -FPS (default: 5). -.sp -For example, if this is set to 1, the video FPS is forced to an integer -multiple of the display FPS, as long as the speed change does not exceed -the value set by \fB\-\-video\-sync\-max\-video\-change\fP\&. -.sp -See \fB\-\-interpolation\-threshold\fP for how this option affects -interpolation. -.sp -This is mostly for testing, and the option may be randomly changed in the -future without notice. -.TP -.B \fB\-\-video\-sync\-max\-video\-change=<value>\fP -Maximum speed difference in percent that is applied to video with -\fB\-\-video\-sync=display\-...\fP (default: 1). Display sync mode will be -disabled if the monitor and video refresh way do not match within the -given range. It tries multiples as well: playing 30 fps video on a 60 Hz -screen will duplicate every second frame. Playing 24 fps video on a 60 Hz -screen will play video in a 2\-3\-2\-3\-... pattern. -.sp -The default settings are not loose enough to speed up 23.976 fps video to -25 fps. We consider the pitch change too extreme to allow this behavior -by default. Set this option to a value of \fB5\fP to enable it. -.sp -Note that in the \fB\-\-video\-sync=display\-resample\fP mode, audio speed will -additionally be changed by a small amount if necessary for A/V sync. See -\fB\-\-video\-sync\-max\-audio\-change\fP\&. -.TP -.B \fB\-\-video\-sync\-max\-audio\-change=<value>\fP -Maximum \fIadditional\fP speed difference in percent that is applied to audio -with \fB\-\-video\-sync=display\-...\fP (default: 0.125). Normally, the player -plays the audio at the speed of the video. But if the difference between -audio and video position is too high, e.g. due to drift or other timing -errors, it will attempt to speed up or slow down audio by this additional -factor. Too low values could lead to video frame dropping or repeating if -the A/V desync cannot be compensated, too high values could lead to chaotic -frame dropping due to the audio "overshooting" and skipping multiple video -frames before the sync logic can react. -.TP -.B \fB\-\-mf\-fps=<value>\fP -Framerate used when decoding from multiple PNG or JPEG files with \fBmf://\fP -(default: 1). -.TP -.B \fB\-\-mf\-type=<value>\fP -Input file type for \fBmf://\fP (available: jpeg, png, tga, sgi).

This specifies the maximum number of frames -the script can request in backward direction. -.sp -E.g. if \fBbuffered\-frames=5\fP, and the script just requested frame 15, -it can still request frame 10, but frame 9 is not available anymore. -If it requests frame 30, mpv will decode 15 more frames, and keep only -frames 25\-30. -.sp -The only reason why this buffer exists is to serve the random access -requests the VapourSynth filter can make. -.sp -The VapourSynth API has a \fBgetFrameAsync\fP function, which takes an -absolute frame number. Source filters must respond to all requests. For -example, a source filter can request frame 2432, and then frame 3. -Source filters typically implement this by pre\-indexing the entire -file. -.sp -mpv on the other hand is stream oriented, and does not allow filters to -seek. (And it would not make sense to allow it, because it would ruin -performance.) Filters get frames sequentially in playback direction, and -cannot request them out of order. -.sp -To compensate for this mismatch, mpv allows the filter to access frames -within a certain window. \fBbuffered\-frames\fP controls the size of this -window. Most VapourSynth filters happen to work with this, because mpv -requests frames sequentially increasing from it, and most filters only -require frames "close" to the requested frame. -.sp -If the filter requests a frame that has a higher frame number than the -highest buffered frame, new frames will be decoded until the requested -frame number is reached. Excessive frames will be flushed out in a FIFO -manner (there are only at most \fBbuffered\-frames\fP in this buffer). -.sp -If the filter requests a frame that has a lower frame number than the -lowest buffered frame, the request cannot be satisfied, and an error -is returned to the filter. This kind of error is not supposed to happen -in a "proper" VapourSynth environment. What exactly happens depends on -the filters involved. -.sp -Increasing this buffer will not improve performance. Rather, it will -waste memory, and slow down seeks (when enough frames to fill the buffer -need to be decoded at once). It is only needed to prevent the error -described in the previous paragraph. -.sp -How many frames a filter requires depends on filter implementation -details, and mpv has no way of knowing. A scale filter might need only -1 frame, an interpolation filter may require a small number of frames, -and the \fBReverse\fP filter will require an infinite number of frames. -.sp -If you want reliable operation to the full extend VapourSynth is -capable, use \fBvspipe\fP\&. -.sp -The actual number of buffered frames also depends on the value of the -\fBconcurrent\-frames\fP option. Currently, both option values are -multiplied to get the final buffer size. -.TP -.B \fBconcurrent\-frames\fP -Number of frames that should be requested in parallel. The -level of concurrency depends on the filter and how quickly mpv can -decode video to feed the filter. This value should probably be -proportional to the number of cores on your machine. Most time, -making it higher than the number of cores can actually make it -slower. -.sp -Technically, mpv will call the VapourSynth \fBgetFrameAsync\fP function -in a loop, until there are \fBconcurrent\-frames\fP frames that have not -been returned by the filter yet. This also assumes that the rest of the -mpv filter chain reads the output of the \fBvapoursynth\fP filter quickly -enough. (For example, if you pause the player, filtering will stop very -soon, because the filtered frames are waiting in a queue.) -.sp -Actual concurrency depends on many other factors. -.sp -By default, this uses the special value \fBauto\fP, which sets the option -to the number of detected logical CPU cores. -.UNINDENT -.sp -The following \fB\&.vpy\fP script variables are defined by mpv: -.INDENT 7.0 -.TP -.B \fBvideo_in\fP -The mpv video source as vapoursynth clip.

They start with \fB\(ga\fP (back\-quote) followed by any ASCII character, -and end at the first occurance of the same pair in reverse order, e.g. -\fB\(ga\-foo\-\(ga\fP or \fB\(ga\(gabar\(ga\(ga\fP\&. The final pair sequence is not allowed at the -value \- in these examples \fB\-\(ga\fP and \fB\(ga\(ga\fP respectively. In the second -example the last character of the value also can\(aqt be a back\-quote. -.sp -Mixed quoting at the same argument, like \fB\(aqfoo\(aq"bar"\fP, is not supported. -.sp -Note that argument parsing and property expansion happen at different stages. -First, arguments are determined as described above, and then, where applicable, -properties are expanded \- regardless of argument quoting. However, expansion -can still be prevented with the \fBraw\fP prefix or \fB$>\fP\&. See \fI\%Input Command -Prefixes\fP and \fI\%Property Expansion\fP\&. -.SS Commands specified as arrays -.sp -This applies to certain APIs, such as \fBmp.commandv()\fP or -\fBmp.command_native()\fP (with array parameters) in Lua scripting, or -\fBmpv_command()\fP or \fBmpv_command_node()\fP (with MPV_FORMAT_NODE_ARRAY) in the -C libmpv client API. -.sp -The command as well as all arguments are passed as a single array. Similar to -the \fI\%Flat command syntax\fP, you can first pass prefixes as strings (each as -separate array item), then the command name as string, and then each argument -as string or a native value. -.sp -Since these APIs pass arguments as separate strings or native values, they do -not expect quotes, and do support escaping. Technically, there is the input.conf -parser, which first splits the command string into arguments, and then invokes -argument parsers for each argument. The input.conf parser normally handles -quotes and escaping. The array command APIs mentioned above pass strings -directly to the argument parsers, or can sidestep them by the ability to pass -non\-string values. -.sp -Property expansion is disabled by default for these APIs. This can be changed -with the \fBexpand\-properties\fP prefix. See \fI\%Input Command Prefixes\fP\&. -.sp -Sometimes commands have string arguments, that in turn are actually parsed by -other components (e.g. filter strings with \fBvf add\fP) \- in these cases, you -you would have to double\-escape in input.conf, but not with the array APIs. -.sp -For complex commands, consider using \fI\%Named arguments\fP instead, which should -give slightly more compatibility. Some commands do not support named arguments -and inherently take an array, though. -.SS Named arguments -.sp -This applies to certain APIs, such as \fBmp.command_native()\fP (with tables that -have string keys) in Lua scripting, or \fBmpv_command_node()\fP (with -MPV_FORMAT_NODE_MAP) in the C libmpv client API. -.sp -The name of the command is provided with a \fBname\fP string field. The name of -each command is defined in each command description in the -\fI\%List of Input Commands\fP\&. \fB\-\-input\-cmdlist\fP also lists them. See the -\fBsubprocess\fP command for an example. -.sp -Some commands do not support named arguments (e.g. \fBrun\fP command). You need -to use APIs that pass arguments as arrays. -.sp -Named arguments are not supported in the "flat" input.conf syntax, which means -you cannot use them for key bindings in input.conf at all. -.sp -Property expansion is disabled by default for these APIs. This can be changed -with the \fBexpand\-properties\fP prefix. See \fI\%Input Command Prefixes\fP\&. -.SS List of Input Commands -.sp -Commands with parameters have the parameter name enclosed in \fB<\fP / \fB>\fP\&. -Don\(aqt add those to the actual command. Optional arguments are enclosed in -\fB[\fP / \fB]\fP\&. If you don\(aqt pass them, they will be set to a default value. -.sp -Remember to quote string arguments in input.conf (see \fI\%Flat command syntax\fP). -.INDENT 0.0 -.TP -.B \fBignore\fP -Use this to "block" keys that should be unbound, and do nothing. Useful for -disabling default bindings, without disabling all bindings with -\fB\-\-no\-input\-default\-bindings\fP\&. -.TP -.B \fBseek <target> [<flags>]\fP -Change the playback position. By default, seeks by a relative amount of -seconds. -.sp -The second argument consists of flags controlling the seek mode: -.INDENT 7.0 -.TP -.B relative (default) -Seek relative to current position (a negative value seeks backwards). -.TP -.B absolute -Seek to a given time (a negative value starts from the end of the file). -.TP -.B absolute\-percent -Seek to a given percent position. -.TP -.B relative\-percent -Seek relative to current position in percent. -.TP -.B keyframes -Always restart playback at keyframe boundaries (fast). -.TP -.B exact -Always do exact/hr/precise seeks (slow). -.UNINDENT -.sp -Multiple flags can be combined, e.g.: \fBabsolute+keyframes\fP\&. -.sp -By default, \fBkeyframes\fP is used for \fBrelative\fP, \fBrelative\-percent\fP, -and \fBabsolute\-percent\fP seeks, while \fBexact\fP is used for \fBabsolute\fP -seeks. -.sp -Before mpv 0.9, the \fBkeyframes\fP and \fBexact\fP flags had to be passed as -3rd parameter (essentially using a space instead of \fB+\fP). The 3rd -parameter is still parsed, but is considered deprecated. -.TP -.B \fBrevert\-seek [<flags>]\fP -Undoes the \fBseek\fP command, and some other commands that seek (but not -necessarily all of them). Calling this command once will jump to the -playback position before the seek. Calling it a second time undoes the -\fBrevert\-seek\fP command itself. This only works within a single file. -.sp -The first argument is optional, and can change the behavior: -.INDENT 7.0 -.TP -.B mark -Mark the current time position. The next normal \fBrevert\-seek\fP command -will seek back to this point, no matter how many seeks happened since -last time. -.TP -.B mark\-permanent -If set, mark the current position, and do not change the mark position -before the next \fBrevert\-seek\fP command that has \fBmark\fP or -\fBmark\-permanent\fP set (or playback of the current file ends). Until -this happens, \fBrevert\-seek\fP will always seek to the marked point. This -flag cannot be combined with \fBmark\fP\&. -.UNINDENT -.sp -Using it without any arguments gives you the default behavior. -.TP -.B \fBframe\-step\fP -Play one frame, then pause. Does nothing with audio\-only playback. -.TP -.B \fBframe\-back\-step\fP -Go back by one frame, then pause. Note that this can be very slow (it tries -to be precise, not fast), and sometimes fails to behave as expected. How -well this works depends on whether precise seeking works correctly (e.g. -see the \fB\-\-hr\-seek\-demuxer\-offset\fP option). Video filters or other video -post\-processing that modifies timing of frames (e.g. deinterlacing) should -usually work, but might make backstepping silently behave incorrectly in -corner cases. Using \fB\-\-hr\-seek\-framedrop=no\fP should help, although it -might make precise seeking slower. -.sp -This does not work with audio\-only playback. -.TP -.B \fBset <name> <value>\fP -Set the given property or option to the given value. -.TP -.B \fBadd <name> [<value>]\fP -Add the given value to the property or option. On overflow or underflow, -clamp the property to the maximum. If \fB<value>\fP is omitted, assume \fB1\fP\&. -.TP -.B \fBcycle <name> [<value>]\fP -Cycle the given property or option. The second argument can be \fBup\fP or -\fBdown\fP to set the cycle direction. On overflow, set the property back to -the minimum, on underflow set it to the maximum. If \fBup\fP or \fBdown\fP is -omitted, assume \fBup\fP\&. -.sp -Whether or not key\-repeat is enabled by default depends on the property. -Currently properties with continuous values are repeatable by default (like -\fBvolume\fP), while discrete values are not (like \fBosd\-level\fP). -.TP -.B \fBmultiply <name> <value>\fP -Similar to \fBadd\fP, but multiplies the property or option with the numeric -value. -.TP -.B \fBscreenshot <flags>\fP -Take a screenshot. -.sp -Multiple flags are available (some can be combined with \fB+\fP): -.INDENT 7.0 -.TP -.B <subtitles> (default) -Save the video image, in its original resolution, and with subtitles. -Some video outputs may still include the OSD in the output under certain -circumstances. -.TP -.B <video> -Like \fBsubtitles\fP, but typically without OSD or subtitles. The exact -behavior depends on the selected video output. -.TP -.B <window> -Save the contents of the mpv window. Typically scaled, with OSD and -subtitles. The exact behavior depends on the selected video output, and -if no support is available, this will act like \fBvideo\fP\&. -.TP -.B <each\-frame> -Take a screenshot each frame. Issue this command again to stop taking -screenshots. Note that you should disable frame\-dropping when using -this mode \- or you might receive duplicate images in cases when a -frame was dropped. This flag can be combined with the other flags, -e.g. \fBvideo+each\-frame\fP\&. -.UNINDENT -.sp -Older mpv versions required passing \fBsingle\fP and \fBeach\-frame\fP as -second argument (and did not have flags). This syntax is still understood, -but deprecated and might be removed in the future. -.sp -If you combine this command with another one using \fB;\fP, you can use the -\fBasync\fP flag to make encoding/writing the image file asynchronous. For -normal standalone commands, this is always asynchronous, and the flag has -no effect. (This behavior changed with mpv 0.29.0.) -.TP -.B \fBscreenshot\-to\-file <filename> <flags>\fP -Take a screenshot and save it to a given file. The format of the file will -be guessed by the extension (and \fB\-\-screenshot\-format\fP is ignored \- the -behavior when the extension is missing or unknown is arbitrary). -.sp -The second argument is like the first argument to \fBscreenshot\fP and -supports \fBsubtitles\fP, \fBvideo\fP, \fBwindow\fP\&. -.sp -If the file already exists, it\(aqs overwritten. -.sp -Like all input command parameters, the filename is subject to property -expansion as described in \fI\%Property Expansion\fP\&. -.TP -.B \fBplaylist\-next <flags>\fP -Go to the next entry on the playlist. -.sp -First argument: -.INDENT 7.0 -.TP -.B weak (default) -If the last file on the playlist is currently played, do nothing. -.TP -.B force -Terminate playback if there are no more files on the playlist. -.UNINDENT -.TP -.B \fBplaylist\-prev <flags>\fP -Go to the previous entry on the playlist. -.sp -First argument: -.INDENT 7.0 -.TP -.B weak (default) -If the first file on the playlist is currently played, do nothing. -.TP -.B force -Terminate playback if the first file is being played. -.UNINDENT -.TP -.B \fBplaylist\-play\-index <integer|current|none>\fP -Start (or restart) playback of the given playlist index. In addition to the -0\-based playlist entry index, it supports the following values: -.INDENT 7.0 -.TP -.B <current> -The current playlist entry (as in \fBplaylist\-current\-pos\fP) will be -played again (unload and reload). If none is set, playback is stopped. -(In corner cases, \fBplaylist\-current\-pos\fP can point to a playlist entry -even if playback is currently inactive, -.TP -.B <none> -Playback is stopped. If idle mode (\fB\-\-idle\fP) is enabled, the player -will enter idle mode, otherwise it will exit. -.UNINDENT -.sp -This comm and is similar to \fBloadfile\fP in that it only manipulates the -state of what to play next, without waiting until the current file is -unloaded, and the next one is loaded. -.sp -Setting \fBplaylist\-pos\fP or similar properties can have a similar effect to -this command. However, it\(aqs more explicit, and guarantees that playback is -restarted if for example the new playlist entry is the same as the previous -one. -.TP -.B \fBloadfile <url> [<flags> [<options>]]\fP -Load the given file or URL and play it. Technically, this is just a playlist -manipulation command (which either replaces the playlist or appends an entry -to it). Actual file loading happens independently. For example, a -\fBloadfile\fP command that replaces the current file with a new one returns -before the current file is stopped, and the new file even begins loading. -.sp -Second argument: -.INDENT 7.0 -.TP -.B <replace> (default) -Stop playback of the current file, and play the new file immediately. -.TP -.B <append> -Append the file to the playlist. -.TP -.B <append\-play> -Append the file, and if nothing is currently playing, start playback. -(Always starts with the added file, even if the playlist was not empty -before running this command.) -.UNINDENT -.sp -The third argument is a list of options and values which should be set -while the file is playing. It is of the form \fBopt1=value1,opt2=value2,..\fP\&. -When using the client API, this can be a \fBMPV_FORMAT_NODE_MAP\fP (or a Lua -table), however the values themselves must be strings currently. These -options are set during playback, and restored to the previous value at end -of playback (see \fI\%Per\-File Options\fP). -.TP -.B \fBloadlist <url> [<flags>]\fP -Load the given playlist file or URL (like \fB\-\-playlist\fP). -.sp -Second argument: -.INDENT 7.0 -.TP -.B <replace> (default) -Stop playback and replace the internal playlist with the new one. -.TP -.B <append> -Append the new playlist at the end of the current internal playlist. -.TP -.B <append\-play> -Append the new playlist, and if nothing is currently playing, start -playback. (Always starts with the new playlist, even if the internal -playlist was not empty before running this command.) -.UNINDENT -.TP -.B \fBplaylist\-clear\fP -Clear the playlist, except the currently played file. -.TP -.B \fBplaylist\-remove <index>\fP -Remove the playlist entry at the given index. Index values start counting -with 0. The special value \fBcurrent\fP removes the current entry. Note that -removing the current entry also stops playback and starts playing the next -entry. -.TP -.B \fBplaylist\-move <index1> <index2>\fP -Move the playlist entry at index1, so that it takes the place of the -entry index2. (Paradoxically, the moved playlist entry will not have -the index value index2 after moving if index1 was lower than index2, -because index2 refers to the target entry, not the index the entry -will have after moving.) -.TP -.B \fBplaylist\-shuffle\fP -Shuffle the playlist. This is similar to what is done on start if the -\fB\-\-shuffle\fP option is used. -.TP -.B \fBplaylist\-unshuffle\fP -Attempt to revert the previous \fBplaylist\-shuffle\fP command. This works -only once (multiple successive \fBplaylist\-unshuffle\fP commands do nothing). -May not work correctly if new recursive playlists have been opened since -a \fBplaylist\-shuffle\fP command. -.TP -.B \fBrun <command> [<arg1> [<arg2> [...]]]\fP -Run the given command. Unlike in MPlayer/mplayer2 and earlier versions of -mpv (0.2.x and older), this doesn\(aqt call the shell. Instead, the command -is run directly, with each argument passed separately. Each argument is -expanded like in \fI\%Property Expansion\fP\&. -.sp -This command has a variable number of arguments, and cannot be used with -named arguments. -.sp -The program is run in a detached way. mpv doesn\(aqt wait until the command -is completed, but continues playback right after spawning it. -.sp -To get the old behavior, use \fB/bin/sh\fP and \fB\-c\fP as the first two -arguments. -.INDENT 7.0 -.INDENT 3.5 -.IP "Example" -.sp -\fBrun "/bin/sh" "\-c" "echo ${title} > /tmp/playing"\fP -.sp -This is not a particularly good example, because it doesn\(aqt handle -escaping, and a specially prepared file might allow an attacker to -execute arbitrary shell commands. It is recommended to write a small -shell script, and call that with \fBrun\fP\&. -.UNINDENT -.UNINDENT -.TP -.B \fBsubprocess\fP -Similar to \fBrun\fP, but gives more control about process execution to the -caller, and does does not detach the process. -.sp -You can avoid blocking until the process terminates by running this command -asynchronously. (For example \fBmp.command_native_async()\fP in Lua scripting.) -.sp -This has the following named arguments. The order of them is not guaranteed, -so you should always call them with named arguments, see \fI\%Named arguments\fP\&. -.INDENT 7.0 -.TP -.B \fBargs\fP (\fBMPV_FORMAT_NODE_ARRAY[MPV_FORMAT_STRING]\fP) -Array of strings with the command as first argument, and subsequent -command line arguments following. This is just like the \fBrun\fP command -argument list. -.sp -The first array entry is either an absolute path to the executable, or -a filename with no path components, in which case the executable is -searched in the directories in the \fBPATH\fP environment variable. On -Unix, this is equivalent to \fBposix_spawnp\fP and \fBexecvp\fP behavior. -.TP -.B \fBplayback_only\fP (\fBMPV_FORMAT_FLAG\fP) -Boolean indicating whether the process should be killed when playback -terminates (optional, default: true). If enabled, stopping playback -will automatically kill the process, and you can\(aqt start it outside of -playback. -.TP -.B \fBcapture_size\fP (\fBMPV_FORMAT_INT64\fP) -Integer setting the maximum number of stdout plus stderr bytes that can -be captured (optional, default: 64MB). If the number of bytes exceeds -this, capturing is stopped. The limit is per captured stream. -.TP -.B \fBcapture_stdout\fP (\fBMPV_FORMAT_FLAG\fP) -Capture all data the process outputs to stdout and return it once the -process ends (optional, default: no). -.TP -.B \fBcapture_stderr\fP (\fBMPV_FORMAT_FLAG\fP) -Same as \fBcapture_stdout\fP, but for stderr. -.TP -.B \fBdetach\fP (\fBMPV_FORMAT_FLAG\fP) -Whether to run the process in detached mode (optional, default: no). In -this mode, the process is run in a new process session, and the command -does not wait for the process to terminate. If neither -\fBcapture_stdout\fP nor \fBcapture_stderr\fP have been set to true, -the command returns immediately after the new process has been started, -otherwise the command will read as long as the pipes are open. -.TP -.B \fBenv\fP (\fBMPV_FORMAT_NODE_ARRAY[MPV_FORMAT_STRING]\fP) -Set a list of environment variables for the new process (default: empty). -If an empty list is passed, the environment of the mpv process is used -instead. (Unlike the underlying OS mechanisms, the mpv command cannot -start a process with empty environment. Fortunately, that is completely -useless.) The format of the list is as in the \fBexecle()\fP syscall. Each -string item defines an environment variable as in \fBNANME=VALUE\fP\&. -.sp -On Lua, you may use \fButils.get_env_list()\fP to retrieve the current -environment if you e.g. simply want to add a new variable. -.TP -.B \fBstdin_data\fP (\fBMPV_FORMAT_STRING\fP) -Feed the given string to the new process\(aq stdin. Since this is a string, -you cannot pass arbitrary binary data. If the process terminates or -closes the pipe before all data is written, the remaining data is -silently discarded. Probably does not work on win32. -.TP -.B \fBpassthrough_stdin\fP (\fBMPV_FORMAT_FLAG\fP) -If enabled, wire the new process\(aq stdin to mpv\(aqs stdin (default: no). -Before mpv 0.33.0, this argument did not exist, but the behavior was as -if this was set to true. -.UNINDENT -.sp -The command returns the following result (as \fBMPV_FORMAT_NODE_MAP\fP): -.INDENT 7.0 -.TP -.B \fBstatus\fP (\fBMPV_FORMAT_INT64\fP) -The raw exit status of the process. It will be negative on error. The -meaning of negative values is undefined, other than meaning error (and -does not correspond to OS low level exit status values). -.sp -On Windows, it can happen that a negative return value is returned -even if the process exits gracefully, because the win32 \fBUINT\fP exit -code is assigned to an \fBint\fP variable before being set as \fBint64_t\fP -field in the result map. This might be fixed later. -.TP -.B \fBstdout\fP (\fBMPV_FORMAT_BYTE_ARRAY\fP) -Captured stdout stream, limited to \fBcapture_size\fP\&. -.TP -.B \fBstderr\fP (\fBMPV_FORMAT_BYTE_ARRAY\fP) -Same as \fBstdout\fP, but for stderr. -.TP -.B \fBerror_string\fP (\fBMPV_FORMAT_STRING\fP) -Empty string if the process exited gracefully. The string \fBkilled\fP if -the process was terminated in an unusual way. The string \fBinit\fP if the -process could not be started. -.sp -On Windows, \fBkilled\fP is only returned when the process has been -killed by mpv as a result of \fBplayback_only\fP being set to true. -.TP -.B \fBkilled_by_us\fP (\fBMPV_FORMAT_FLAG\fP) -Whether the process has been killed by mpv, for example as a result of -\fBplayback_only\fP being set to true, aborting the command (e.g. by -\fBmp.abort_async_command()\fP), or if the player is about to exit. -.UNINDENT -.sp -Note that the command itself will always return success as long as the -parameters are correct. Whether the process could be spawned or whether -it was somehow killed or returned an error status has to be queried from -the result value. -.sp -This command can be asynchronously aborted via API. -.sp -In all cases, the subprocess will be terminated on player exit.

Unlike in the other -cases, the second parameter is a comma separated list of filter names -or integer indexes. \fB0\fP would denote the first filter. Negative -indexes start from the last filter, and \fB\-1\fP denotes the last -filter. Deprecated, use \fBremove\fP\&. -.TP -.B <clr> -Remove all filters.

The \fBcontents\fP parameter uses the same syntax as the -\fBinput.conf\fP file (except that using the section syntax in it is not -allowed), including the need to separate bindings with a newline character. -.sp -If the \fBcontents\fP parameter is an empty string, the section is removed. -.sp -The section with the name \fBdefault\fP is the normal input section. -.sp -In general, input sections have to be enabled with the \fBenable\-section\fP -command, or they are ignored. -.sp -The last parameter has the following meaning: -.INDENT 7.0 -.TP -.B <default> (also used if parameter omitted) -Use a key binding defined by this section only if the user hasn\(aqt -already bound this key to a command. -.TP -.B <force> -Always bind a key. (The input section that was made active most recently -wins if there are ambiguities.) -.UNINDENT -.sp -This command can be used to dispatch arbitrary keys to a script or a client -API user.

The special key name \fBunmapped\fP can be -used to match any unmapped key. -.TP -.B \fBoverlay\-add <id> <x> <y> <file> <offset> <fmt> <w> <h> <stride>\fP -Add an OSD overlay sourced from raw data. This might be useful for scripts -and applications controlling mpv, and which want to display things on top -of the video window. -.sp -Overlays are usually displayed in screen resolution, but with some VOs, -the resolution is reduced to that of the video\(aqs. You can read the -\fBosd\-width\fP and \fBosd\-height\fP properties. At least with \fB\-\-vo\-xv\fP and -anamorphic video (such as DVD), \fBosd\-par\fP should be read as well, and the -overlay should be aspect\-compensated. -.sp -This has the following named arguments. The order of them is not guaranteed, -so you should always call them with named arguments, see \fI\%Named arguments\fP\&. -.sp -\fBid\fP is an integer between 0 and 63 identifying the overlay element. The -ID can be used to add multiple overlay parts, update a part by using this -command with an already existing ID, or to remove a part with -\fBoverlay\-remove\fP\&. Using a previously unused ID will add a new overlay, -while reusing an ID will update it. -.sp -\fBx\fP and \fBy\fP specify the position where the OSD should be displayed. -.sp -\fBfile\fP specifies the file the raw image data is read from. It can be -either a numeric UNIX file descriptor prefixed with \fB@\fP (e.g. \fB@4\fP), -or a filename. The file will be mapped into memory with \fBmmap()\fP, -copied, and unmapped before the command returns (changed in mpv 0.18.1). -.sp -It is also possible to pass a raw memory address for use as bitmap memory -by passing a memory address as integer prefixed with an \fB&\fP character. -Passing the wrong thing here will crash the player. This mode might be -useful for use with libmpv. The \fBoffset\fP parameter is simply added to the -memory address (since mpv 0.8.0, ignored before). -.sp -\fBoffset\fP is the byte offset of the first pixel in the source file. -(The current implementation always mmap\(aqs the whole file from position 0 to -the end of the image, so large offsets should be avoided. Before mpv 0.8.0, -the offset was actually passed directly to \fBmmap\fP, but it was changed to -make using it easier.) -.sp -\fBfmt\fP is a string identifying the image format. Currently, only \fBbgra\fP -is defined. This format has 4 bytes per pixels, with 8 bits per component. -The least significant 8 bits are blue, and the most significant 8 bits -are alpha (in little endian, the components are B\-G\-R\-A, with B as first -byte). This uses premultiplied alpha: every color component is already -multiplied with the alpha component. This means the numeric value of each -component is equal to or smaller than the alpha component. (Violating this -rule will lead to different results with different VOs: numeric overflows -resulting from blending broken alpha values is considered something that -shouldn\(aqt happen, and consequently implementations don\(aqt ensure that you -get predictable behavior in this case.) -.sp -\fBw\fP, \fBh\fP, and \fBstride\fP specify the size of the overlay. \fBw\fP is the -visible width of the overlay, while \fBstride\fP gives the width in bytes in -memory. In the simple case, and with the \fBbgra\fP format, \fBstride==4*w\fP\&. -In general, the total amount of memory accessed is \fBstride * h\fP\&. -(Technically, the minimum size would be \fBstride * (h \- 1) + w * 4\fP, but -for simplicity, the player will access all \fBstride * h\fP bytes.) -.sp -\fBNOTE:\fP -.INDENT 7.0 -.INDENT 3.5 -Before mpv 0.18.1, you had to do manual "double buffering" when updating -an overlay by replacing it with a different memory buffer. Since mpv -0.18.1, the memory is simply copied and doesn\(aqt reference any of the -memory indicated by the command\(aqs arguments after the commend returns. -If you want to use this command before mpv 0.18.1, reads the old docs -to see how to handle this correctly. -.UNINDENT -.UNINDENT -.TP -.B \fBoverlay\-remove <id>\fP -Remove an overlay added with \fBoverlay\-add\fP and the same ID. Does nothing -if no overlay with this ID exists. -.TP -.B \fBosd\-overlay\fP -Add/update/remove an OSD overlay. -.sp -(Although this sounds similar to \fBoverlay\-add\fP, \fBosd\-overlay\fP is for -text overlays, while \fBoverlay\-add\fP is for bitmaps. Maybe \fBoverlay\-add\fP -will be merged into \fBosd\-overlay\fP to remove this oddity.) -.sp -You can use this to add text overlays in ASS format. ASS has advanced -positioning and rendering tags, which can be used to render almost any kind -of vector graphics. -.sp -This command accepts the following parameters: -.INDENT 7.0 -.TP -.B \fBid\fP -Arbitrary integer that identifies the overlay. Multiple overlays can be -added by calling this command with different \fBid\fP parameters. Calling -this command with the same \fBid\fP replaces the previously set overlay. -.sp -There is a separate namespace for each libmpv client (i.e. IPC -connection, script), so IDs can be made up and assigned by the API user -without conflicting with other API users. -.sp -If the libmpv client is destroyed, all overlays associated with it are -also deleted. In particular, connecting via \fB\-\-input\-ipc\-server\fP, -adding an overlay, and disconnecting will remove the overlay immediately -again. -.TP -.B \fBformat\fP -String that gives the type of the overlay. Accepts the following values -(HTML rendering of this is broken, view the generated manpage instead, -or the raw RST source): -.INDENT 7.0 -.TP -.B \fBass\-events\fP -The \fBdata\fP parameter is a string. The string is split on the -newline character. Every line is turned into the \fBText\fP part of -a \fBDialogue\fP ASS event. Timing is unused (but behavior of timing -dependent ASS tags may change in future mpv versions). -.sp -Note that it\(aqs better to put multiple lines into \fBdata\fP, instead -of adding multiple OSD overlays. -.sp -This provides 2 ASS \fBStyles\fP\&. \fBOSD\fP contains the text style as -defined by the current \fB\-\-osd\-...\fP options. \fBDefault\fP is -similar, and contains style that \fBOSD\fP would have if all options -were set to the default. -.sp -In addition, the \fBres_x\fP and \fBres_y\fP options specify the value -of the ASS \fBPlayResX\fP and \fBPlayResY\fP header fields. If \fBres_y\fP -is set to 0, \fBPlayResY\fP is initialized to an arbitrary default -value (but note that the default for this command is 720, not 0). -If \fBres_x\fP is set to 0, \fBPlayResX\fP is set based on \fBres_y\fP -such that a virtual ASS pixel has a square pixel aspect ratio. -.TP -.B \fBnone\fP -Special value that causes the overlay to be removed. Most parameters -other than \fBid\fP and \fBformat\fP are mostly ignored. -.UNINDENT -.TP -.B \fBdata\fP -String defining the overlay contents according to the \fBformat\fP -parameter. -.TP -.B \fBres_x\fP, \fBres_y\fP -Used if \fBformat\fP is set to \fBass\-events\fP (see description there). -Optional, defaults to 0/720. -.TP -.B \fBz\fP -The Z order of the overlay. Optional, defaults to 0. -.sp -Note that Z order between different overlays of different formats is -static, and cannot be changed (currently, this means that bitmap -overlays added by \fBoverlay\-add\fP are always on top of the ASS overlays -added by \fBosd\-overlay\fP). In addition, the builtin OSD components are -always below any of the custom OSD. (This includes subtitles of any kind -as well as text rendered by \fBshow\-text\fP\&.) -.sp -It\(aqs possible that future mpv versions will randomly change how Z order -between different OSD formats and builtin OSD is handled. -.TP -.B \fBhidden\fP -If set to true, do not display this (default: false). -.TP -.B \fBcompute_bounds\fP -If set to true, attempt to determine bounds and write them to the -command\(aqs result value as \fBx0\fP, \fBx1\fP, \fBy0\fP, \fBy1\fP rectangle -(default: false). If the rectangle is empty, not known, or somehow -degenerate, it is not set. \fBx1\fP/\fBy1\fP is the coordinate of the -bottom exclusive corner of the rectangle. -.sp -The result value may depend on the VO window size, and is based on the -last known window size at the time of the call. This means the results -may be different from what is actually rendered. -.sp -For \fBass\-events\fP, the result rectangle is recomputed to \fBPlayRes\fP -coordinates (\fBres_x\fP/\fBres_y\fP). If window size is not known, a -fallback is chosen. -.sp -You should be aware that this mechanism is very inefficient, as it -renders the full result, and then uses the bounding box of the rendered -bitmap list (even if \fBhidden\fP is set). It will flush various caches. -Its results also depend on the used libass version. -.sp -This feature is experimental, and may change in some way again. -.UNINDENT -.sp -\fBNOTE:\fP -.INDENT 7.0 -.INDENT 3.5 -Always use named arguments (\fBmpv_command_node()\fP). Lua scripts should -use the \fBmp.create_osd_overlay()\fP helper instead of invoking this -command directly. -.UNINDENT -.UNINDENT -.TP -.B \fBscript\-message [<arg1> [<arg2> [...]]]\fP -Send a message to all clients, and pass it the following list of arguments. -What this message means, how many arguments it takes, and what the arguments -mean is fully up to the receiver and the sender. Every client receives the -message, so be careful about name clashes (or use \fBscript\-message\-to\fP). -.sp -This command has a variable number of arguments, and cannot be used with -named arguments. -.TP -.B \fBscript\-message\-to <target> [<arg1> [<arg2> [...]]]\fP -Same as \fBscript\-message\fP, but send it only to the client named -\fB<target>\fP\&. Each client (scripts etc.) has a unique name. For example, -Lua scripts can get their name via \fBmp.get_script_name()\fP\&. Note that -client names only consist of alphanumeric characters and \fB_\fP\&. -.sp -This command has a variable number of arguments, and cannot be used with -named arguments. -.TP -.B \fBscript\-binding <name>\fP -Invoke a script\-provided key binding. This can be used to remap key -bindings provided by external Lua scripts. -.sp -The argument is the name of the binding. -.sp -It can optionally be prefixed with the name of the script, using \fB/\fP as -separator, e.g. \fBscript\-binding scriptname/bindingname\fP\&. Note that script -names only consist of alphanumeric characters and \fB_\fP\&. -.sp -For completeness, here is how this command works internally. The details -could change any time. On any matching key event, \fBscript\-message\-to\fP -or \fBscript\-message\fP is called (depending on whether the script name is -included), with the following arguments: -.INDENT 7.0 -.IP 1. 3 -The string \fBkey\-binding\fP\&. -.IP 2. 3 -The name of the binding (as established above). -.IP 3. 3 -The key state as string (see below). -.IP 4. 3 -The key name (since mpv 0.15.0). -.IP 5. 3 -The text the key would produce, or empty string if not applicable. -.UNINDENT -.sp -The 5th argument is only set if no modifiers are present (using the shift -key with a letter is normally not emitted as having a modifier, and results -in upper case text instead, but some backends may mess up). -.sp -The key state consists of 2 characters: -.INDENT 7.0 -.IP 1. 3 -One of \fBd\fP (key was pressed down), \fBu\fP (was released), \fBr\fP (key -is still down, and was repeated; only if key repeat is enabled for this -binding), \fBp\fP (key was pressed; happens if up/down can\(aqt be tracked). -.IP 2. 3 -Whether the event originates from the mouse, either \fBm\fP (mouse button) -or \fB\-\fP (something else). -.UNINDENT -.sp -Future versions can add more arguments and more key state characters to -support more input peculiarities. -.TP -.B \fBab\-loop\fP -Cycle through A\-B loop states. The first command will set the \fBA\fP point -(the \fBab\-loop\-a\fP property); the second the \fBB\fP point, and the third -will clear both points. -.TP -.B \fBdrop\-buffers\fP -Drop audio/video/demuxer buffers, and restart from fresh. Might help with -unseekable streams that are going out of sync. -This command might be changed or removed in the future. -.TP -.B \fBscreenshot\-raw [<flags>]\fP -Return a screenshot in memory. This can be used only through the client -API. The MPV_FORMAT_NODE_MAP returned by this command has the \fBw\fP, \fBh\fP, -\fBstride\fP fields set to obvious contents. The \fBformat\fP field is set to -\fBbgr0\fP by default. This format is organized as \fBB8G8R8X8\fP (where \fBB\fP -is the LSB). The contents of the padding \fBX\fP are undefined. The \fBdata\fP -field is of type MPV_FORMAT_BYTE_ARRAY with the actual image data. The image -is freed as soon as the result mpv_node is freed. As usual with client API -semantics, you are not allowed to write to the image data. -.sp -The \fBstride\fP is the number of bytes from a pixel at \fB(x0, y0)\fP to the -pixel at \fB(x0, y0 + 1)\fP\&. This can be larger than \fBw * 4\fP if the image -was cropped, or if there is padding. This number can be negative as well. -You access a pixel with \fBbyte_index = y * stride + x * 4\fP (assuming the -\fBbgr0\fP format). -.sp -The \fBflags\fP argument is like the first argument to \fBscreenshot\fP and -supports \fBsubtitles\fP, \fBvideo\fP, \fBwindow\fP\&. -.TP -.B \fBvf\-command <label> <command> <argument>\fP -Send a command to the filter with the given \fB<label>\fP\&. Use \fBall\fP to send -it to all filters at once. The command and argument string is filter -specific. Currently, this only works with the \fBlavfi\fP filter \- see -the libavfilter documentation for which commands a filter supports. -.sp -Note that the \fB<label>\fP is a mpv filter label, not a libavfilter filter -name. -.TP -.B \fBaf\-command <label> <command> <argument>\fP -Same as \fBvf\-command\fP, but for audio filters. -.TP -.B \fBapply\-profile <name> [<mode>]\fP -Apply the contents of a named profile. This is like using \fBprofile=name\fP -in a config file, except you can map it to a key binding to change it at -runtime. -.sp -The mode argument: -.INDENT 7.0 -.TP -.B \fBdefault\fP -Apply the profile. Default if the argument is omitted. -.TP -.B \fBrestore\fP -Restore options set by a previous \fBapply\-profile\fP command for this -profile. Only works if the profile has \fBprofile\-restore\fP set to a -relevant mode. Prints a warning if nothing could be done. See -\fI\%Runtime profiles\fP for details. -.UNINDENT -.TP -.B \fBload\-script <filename>\fP -Load a script, similar to the \fB\-\-script\fP option. Whether this waits for -the script to finish initialization or not changed multiple times, and the -future behavior is left undefined. -.sp -On success, returns a \fBmpv_node\fP with a \fBclient_id\fP field set to the -return value of the \fBmpv_client_id()\fP API call of the newly created script -handle. -.TP -.B \fBchange\-list <name> <operation> <value>\fP -This command changes list options as described in \fI\%List Options\fP\&. The -\fB<name>\fP parameter is the normal option name, while \fB<operation>\fP is -the suffix or action used on the option. -.sp -Some operations take no value, but the command still requires the value -parameter. In these cases, the value must be an empty string. -.INDENT 7.0 -.INDENT 3.5 -.IP "Example" -.sp -\fBchange\-list glsl\-shaders append file.glsl\fP -.sp -Add a filename to the \fBglsl\-shaders\fP list.

The \fB<filename>\fP file is -overwritten if it already exists. \fB<start>\fP and \fB<end>\fP give the -time range of what to dump. If no data is cached at the given time range, -nothing may be dumped (creating a file with no packets). -.sp -Dumping a larger part of the cache will freeze the player. No effort was -made to fix this, as this feature was meant mostly for creating small -excerpts. -.sp -See \fB\-\-stream\-record\fP for various caveats that mostly apply to this -command too, as both use the same underlying code for writing the output -file. -.sp -If \fB<filename>\fP is an empty string, an ongoing \fBdump\-cache\fP is stopped. -.sp -If \fB<end>\fP is \fBno\fP, then continuous dumping is enabled. Then, after -dumping the existing parts of the cache, anything read from network is -appended to the cache as well. This behaves similar to \fB\-\-stream\-record\fP -(although it does not conflict with that option, and they can be both active -at the same time). -.sp -If the \fB<end>\fP time is after the cache, the command will _not_ wait and -write newly received data to it. -.sp -The end of the resulting file may be slightly damaged or incomplete at the -end. (Not enough effort was made to ensure that the end lines up properly.) -.sp -Note that this command will finish only once dumping ends. That means it -works similar to the \fBscreenshot\fP command, just that it can block much -longer. If continuous dumping is used, the command will not finish until -playback is stopped, an error happens, another \fBdump\-cache\fP command is -run, or an API like \fBmp.abort_async_command\fP was called to explicitly stop -the command. See \fI\%Synchronous vs. Asynchronous\fP\&. -.sp -\fBNOTE:\fP -.INDENT 7.0 -.INDENT 3.5 -This was mostly created for network streams. For local files, there may -be much better methods to create excerpts and such. There are tons of -much more user\-friendly Lua scripts, that will reencode parts of a file -by spawning a separate instance of \fBffmpeg\fP\&. With network streams, -this is not that easily possible, as the stream would have to be -downloaded again. Even if \fB\-\-stream\-record\fP is used to record the -stream to the local filesystem, there may be problems, because the -recorded file is still written to. -.UNINDENT -.UNINDENT -.sp -This command is experimental, and all details about it may change in the -future. -.TP -.B \fBab\-loop\-dump\-cache <filename>\fP -Essentially calls \fBdump\-cache\fP with the current AB\-loop points as -arguments. Like \fBdump\-cache\fP, this will overwrite the file at -\fB<filename>\fP\&. Likewise, if the B point is set to \fBno\fP, it will enter -continuous dumping after the existing cache was dumped. -.sp -The author reserves the right to remove this command if enough motivation -is found to move this functionality to a trivial Lua script. -.TP -.B \fBab\-loop\-align\-cache\fP -Re\-adjust the A/B loop points to the start and end within the cache the -\fBab\-loop\-dump\-cache\fP command will (probably) dump. Basically, it aligns -the times on keyframes. The guess might be off especially at the end (due to -granularity issues due to remuxing). If the cache shrinks in the meantime, -the points set by the command will not be the effective parameters either. -.sp -This command has an even more uncertain future than \fBab\-loop\-dump\-cache\fP -and might disappear without replacement if the author decides it\(aqs useless. -.UNINDENT -.sp -Undocumented commands: \fBao\-reload\fP (experimental/internal). -.SS List of events -.sp -This is a partial list of events.

Note that the C API has separate C\-level declarations with -\fBmpv_event\fP, which may be slightly different. -.sp -Note that events are asynchronous: the player core continues running while -events are delivered to scripts and other clients. In some cases, you can hooks -to enforce synchronous execution. -.sp -All events can have the following fields: -.INDENT 0.0 -.TP -.B \fBevent\fP -Name as the event (as returned by \fBmpv_event_name()\fP). -.TP -.B \fBid\fP -The \fBreply_userdata\fP field (opaque user value).

Typically, the player will load the -next file right away, or quit if this was the last file. -.sp -The event has the following fields: -.INDENT 7.0 -.TP -.B \fBreason\fP -Has one of these values: -.INDENT 7.0 -.TP -.B \fBeof\fP -The file has ended. This can (but doesn\(aqt have to) include -incomplete files or broken network connections under -circumstances. -.TP -.B \fBstop\fP -Playback was ended by a command. -.TP -.B \fBquit\fP -Playback was ended by sending the quit command. -.TP -.B \fBerror\fP -An error happened. In this case, an \fBerror\fP field is present with -the error string. -.TP -.B \fBredirect\fP -Happens with playlists and similar. Details see -\fBMPV_END_FILE_REASON_REDIRECT\fP in the C API. -.TP -.B \fBunknown\fP -Unknown. Normally doesn\(aqt happen, unless the Lua API is out of sync -with the C API. (Likewise, it could happen that your script gets -reason strings that did not exist yet at the time your script was -written.) -.UNINDENT -.TP -.B \fBplaylist_entry_id\fP -Playlist entry ID of the file that was being played or attempted to be -played. This has the same value as the \fBplaylist_entry_id\fP field in the -corresponding \fBstart\-file\fP event. -.TP -.B \fBfile_error\fP -Set to mpv error string describing the approximate reason why playback -failed. Unset if no error known. (In Lua scripting, this value was set -on the \fBerror\fP field directly. This is deprecated since mpv 0.33.0. -In the future, this \fBerror\fP field will be unset for this specific -event.) -.TP -.B \fBplaylist_insert_id\fP -If loading ended, because the playlist entry to be played was for example -a playlist, and the current playlist entry is replaced with a number of -other entries. This may happen at least with MPV_END_FILE_REASON_REDIRECT -(other event types may use this for similar but different purposes in the -future). In this case, playlist_insert_id will be set to the playlist -entry ID of the first inserted entry, and playlist_insert_num_entries to -the total number of inserted playlist entries. Note this in this specific -case, the ID of the last inserted entry is playlist_insert_id+num\-1. -Beware that depending on circumstances, you may observe the new playlist -entries before seeing the event (e.g. reading the "playlist" property or -getting a property change notification before receiving the event). -If this is 0 in the C API, this field isn\(aqt added. -.TP -.B \fBplaylist_insert_num_entries\fP -See playlist_insert_id. Only present if playlist_insert_id is present. -.UNINDENT -.TP -.B \fBfile\-loaded\fP (\fBMPV_EVENT_FILE_LOADED\fP) -Happens after a file was loaded and begins playback. -.TP -.B \fBseek\fP (\fBMPV_EVENT_SEEK\fP) -Happens on seeking. (This might include cases when the player seeks -internally, even without user interaction. This includes e.g. segment -changes when playing ordered chapters Matroska files.) -.TP -.B \fBplayback\-restart\fP (\fBMPV_EVENT_PLAYBACK_RESTART\fP) -Start of playback after seek or after file was loaded. -.TP -.B \fBshutdown\fP (\fBMPV_EVENT_SHUTDOWN\fP) -Sent when the player quits, and the script should terminate. Normally -handled automatically.

This is what -the terminal player puts in front of the message text when using the -\fB\-\-v\fP option, and is also what is used for \fB\-\-msg\-level\fP\&. -.TP -.B \fBlevel\fP -The log level as string. See \fBmsg.log\fP for possible log level names. -Note that later versions of mpv might add new levels or remove -(undocumented) existing ones. -.TP -.B \fBtext\fP -The log message. The text will end with a newline character. Sometimes -it can contain multiple lines. -.UNINDENT -.sp -Keep in mind that these messages are meant to be hints for humans.

Use \fBmpv_observe_property()\fP -(Lua: \fBmp.observe_property()\fP) instead. -.SS Hooks -.sp -Hooks are synchronous events between player core and a script or similar. This -applies to client API (including the Lua scripting interface). Normally, -events are supposed to be asynchronous, and the hook API provides an awkward -and obscure way to handle events that require stricter coordination. There are -no API stability guarantees made. Not following the protocol exactly can make -the player freeze randomly. Basically, nobody should use this API. -.sp -The C API is described in the header files. The Lua API is described in the -Lua section. -.sp -Before a hook is actually invoked on an API clients, it will attempt to return -new values for all observed properties that were changed before the hook. This -may make it easier for an application to set defined "barriers" between property -change notifications by registering hooks. (That means these hooks will have an -effect, even if you do nothing and make them continue immediately.) -.sp -The following hooks are currently defined: -.INDENT 0.0 -.TP -.B \fBon_load\fP -Called when a file is to be opened, before anything is actually done. -For example, you could read and write the \fBstream\-open\-filename\fP -property to redirect an URL to something else (consider support for -streaming sites which rarely give the user a direct media URL), or -you could set per\-file options with by setting the property -\fBfile\-local\-options/<option name>\fP\&. The player will wait until all -hooks are run. -.sp -Ordered after \fBstart\-file\fP and before \fBplayback\-restart\fP\&. -.TP -.B \fBon_load_fail\fP -Called after after a file has been opened, but failed to. This can be -used to provide a fallback in case native demuxers failed to recognize -the file, instead of always running before the native demuxers like -\fBon_load\fP\&. Demux will only be retried if \fBstream\-open\-filename\fP -was changed. If it fails again, this hook is _not_ called again, and -loading definitely fails. -.sp -Ordered after \fBon_load\fP, and before \fBplayback\-restart\fP and \fBend\-file\fP\&. -.TP -.B \fBon_preloaded\fP -Called after a file has been opened, and before tracks are selected and -decoders are created. This has some usefulness if an API users wants -to select tracks manually, based on the set of available tracks. It\(aqs -also useful to initialize \fB\-\-lavfi\-complex\fP in a specific way by API, -without having to "probe" the available streams at first. -.sp -Note that this does not yet apply default track selection. Which operations -exactly can be done and not be done, and what information is available and -what is not yet available yet, is all subject to change. -.sp -Ordered after \fBon_load_fail\fP etc. and before \fBplayback\-restart\fP\&. -.TP -.B \fBon_unload\fP -Run before closing a file, and before actually uninitializing -everything. It\(aqs not possible to resume playback in this state. -.sp -Ordered before \fBend\-file\fP\&. Will also happen in the error case (then after -\fBon_load_fail\fP). -.TP -.B \fBon_before_start_file\fP -Run before a \fBstart\-file\fP event is sent. (If any client changes the -current playlist entry, or sends a quit command to the player, the -corresponding event will not actually happen after the hook returns.) -Useful to drain property changes before a new file is loaded. -.TP -.B \fBon_after_end_file\fP -Run after an \fBend\-file\fP event. Useful to drain property changes after a -file has finished. -.UNINDENT -.SS Input Command Prefixes -.sp -These prefixes are placed between key name and the actual command. Multiple -prefixes can be specified. They are separated by whitespace. -.INDENT 0.0 -.TP -.B \fBosd\-auto\fP -Use the default behavior for this command. This is the default for -\fBinput.conf\fP commands. Some libmpv/scripting/IPC APIs do not use this as -default, but use \fBno\-osd\fP instead. -.TP -.B \fBno\-osd\fP -Do not use any OSD for this command. -.TP -.B \fBosd\-bar\fP -If possible, show a bar with this command. Seek commands will show the -progress bar, property changing commands may show the newly set value. -.TP -.B \fBosd\-msg\fP -If possible, show an OSD message with this command. Seek command show -the current playback time, property changing commands show the newly set -value as text. -.TP -.B \fBosd\-msg\-bar\fP -Combine osd\-bar and osd\-msg. -.TP -.B \fBraw\fP -Do not expand properties in string arguments. (Like \fB"${property\-name}"\fP\&.) -This is the default for some libmpv/scripting/IPC APIs. -.TP -.B \fBexpand\-properties\fP -All string arguments are expanded as described in \fI\%Property Expansion\fP\&. -This is the default for \fBinput.conf\fP commands. -.TP -.B \fBrepeatable\fP -For some commands, keeping a key pressed doesn\(aqt run the command repeatedly. -This prefix forces enabling key repeat in any case. For a list of commands: -the first command determines the repeatability of the whole list (up to and -including version 0.33 \- a list was always repeatable). -.TP -.B \fBasync\fP -Allow asynchronous execution (if possible). Note that only a few commands -will support this (usually this is explicitly documented). Some commands -are asynchronous by default (or rather, their effects might manifest -after completion of the command). The semantics of this flag might change -in the future. Set it only if you don\(aqt rely on the effects of this command -being fully realized when it returns. See \fI\%Synchronous vs. Asynchronous\fP\&. -.TP -.B \fBsync\fP -Allow synchronous execution (if possible). Normally, all commands are -synchronous by default, but some are asynchronous by default for -compatibility with older behavior. -.UNINDENT -.sp -All of the osd prefixes are still overridden by the global \fB\-\-osd\-level\fP -settings. -.SS Synchronous vs. Asynchronous -.sp -The \fBasync\fP and \fBsync\fP prefix matter only for how the issuer of the command -waits on the completion of the command. Normally it does not affect how the -command behaves by itself. There are the following cases: -.INDENT 0.0 -.IP \(bu 2 -Normal input.conf commands are always run asynchronously. Slow running -commands are queued up or run in parallel. -.IP \(bu 2 -"Multi" input.conf commands (1 key binding, concatenated with \fB;\fP) will be -executed in order, except for commands that are async (either prefixed with -\fBasync\fP, or async by default for some commands). The async commands are -run in a detached manner, possibly in parallel to the remaining sync commands -in the list. -.IP \(bu 2 -Normal Lua and libmpv commands (e.g. \fBmpv_command()\fP) are run in a blocking -manner, unless the \fBasync\fP prefix is used, or the command is async by -default. This means in the sync case the caller will block, even if the core -continues playback. Async mode runs the command in a detached manner. -.IP \(bu 2 -Async libmpv command API (e.g. \fBmpv_command_async()\fP) never blocks the -caller, and always notify their completion with a message. The \fBsync\fP and -\fBasync\fP prefixes make no difference. -.IP \(bu 2 -Lua also provides APIs for running async commands, which behave similar to the -C counterparts. -.IP \(bu 2 -In all cases, async mode can still run commands in a synchronous manner, even -in detached mode. This can for example happen in cases when a command does not -have an asynchronous implementation. The async libmpv API still never blocks -the caller in these cases. -.UNINDENT -.sp -Before mpv 0.29.0, the \fBasync\fP prefix was only used by screenshot commands, -and made them run the file saving code in a detached manner. This is the -default now, and \fBasync\fP changes behavior only in the ways mentioned above. -.sp -Currently the following commands have different waiting characteristics with -sync vs. async: sub\-add, audio\-add, sub\-reload, audio\-reload, -rescan\-external\-files, screenshot, screenshot\-to\-file, dump\-cache, -ab\-loop\-dump\-cache. -.SS Asynchronous command details -.sp -On the API level, every asynchronous command is bound to the context which -started it. For example, an asynchronous command started by \fBmpv_command_async\fP -is bound to the \fBmpv_handle\fP passed to the function. Only this \fBmpv_handle\fP -receives the completion notification (\fBMPV_EVENT_COMMAND_REPLY\fP), and only -this handle can abort a still running command directly. If the \fBmpv_handle\fP is -destroyed, any still running async. commands started by it are terminated. -.sp -The scripting APIs and JSON IPC give each script/connection its own implicit -\fBmpv_handle\fP\&. -.sp -If the player is closed, the core may abort all pending async. commands on its -own (like a forced \fBmpv_abort_async_command()\fP call for each pending command -on behalf of the API user). This happens at the same time \fBMPV_EVENT_SHUTDOWN\fP -is sent, and there is no way to prevent this. -.SS Input Sections -.sp -Input sections group a set of bindings, and enable or disable them at once. -In \fBinput.conf\fP, each key binding is assigned to an input section, rather -than actually having explicit text sections. -.sp -See also: \fBenable\-section\fP and \fBdisable\-section\fP commands. -.sp -Predefined bindings: -.INDENT 0.0 -.TP -.B \fBdefault\fP -Bindings without input section are implicitly assigned to this section. It -is enabled by default during normal playback. -.TP -.B \fBencode\fP -Section which is active in encoding mode. It is enabled exclusively, so -that bindings in the \fBdefault\fP sections are ignored. -.UNINDENT -.SS Properties -.sp -Properties are used to set mpv options during runtime, or to query arbitrary -information. They can be manipulated with the \fBset\fP/\fBadd\fP/\fBcycle\fP -commands, and retrieved with \fBshow\-text\fP, or anything else that uses property -expansion. (See \fI\%Property Expansion\fP\&.) -.sp -The property name is annotated with RW to indicate whether the property is -generally writable. -.sp -If an option is referenced, the property will normally take/return exactly the -same values as the option. In these cases, properties are merely a way to change -an option at runtime. -.SS Property list -.sp -\fBNOTE:\fP -.INDENT 0.0 -.INDENT 3.5 -Most options can be set as runtime via properties as well. Just remove the -leading \fB\-\-\fP from the option name. These are not documented below, see -\fI\%OPTIONS\fP instead. Only properties which do not exist as option with the -same name, or which have very different behavior from the options are -documented below. -.sp -Properties marked as (RW) are writeable, while those that aren\(aqt are -read\-only. -.UNINDENT -.UNINDENT -.INDENT 0.0 -.TP -.B \fBaudio\-speed\-correction\fP, \fBvideo\-speed\-correction\fP -Factor multiplied with \fBspeed\fP at which the player attempts to play the -file. Usually it\(aqs exactly 1. (Display sync mode will make this useful.) -.sp -OSD formatting will display it in the form of \fB+1.23456%\fP, with the number -being \fB(raw \- 1) * 100\fP for the given raw property value. -.TP -.B \fBdisplay\-sync\-active\fP -Whether \fB\-\-video\-sync=display\fP is actually active. -.TP -.B \fBfilename\fP -Currently played file, with path stripped. If this is an URL, try to undo -percent encoding as well. (The result is not necessarily correct, but -looks better for display purposes. Use the \fBpath\fP property to get an -unmodified filename.) -.sp -This has a sub\-property: -.INDENT 7.0 -.TP -.B \fBfilename/no\-ext\fP -Like the \fBfilename\fP property, but if the text contains a \fB\&.\fP, strip -all text after the last \fB\&.\fP\&. Usually this removes the file extension. -.UNINDENT -.TP -.B \fBfile\-size\fP -Length in bytes of the source file/stream. (This is the same as -\fB${stream\-end}\fP\&. For segmented/multi\-part files, this will return the -size of the main or manifest file, whatever it is.) -.TP -.B \fBestimated\-frame\-count\fP -Total number of frames in current file. -.sp -\fBNOTE:\fP -.INDENT 7.0 -.INDENT 3.5 -This is only an estimate.

(It\(aqs computed from two unreliable -quantities: fps and possibly rounded timestamps.) -.UNINDENT -.UNINDENT -.TP -.B \fBpid\fP -Process\-id of mpv. -.TP -.B \fBpath\fP -Full path of the currently played file. Usually this is exactly the same -string you pass on the mpv command line or the \fBloadfile\fP command, even -if it\(aqs a relative path. If you expect an absolute path, you will have to -determine it yourself, for example by using the \fBworking\-directory\fP -property. -.TP -.B \fBstream\-open\-filename\fP -The full path to the currently played media. This is different from -\fBpath\fP only in special cases. In particular, if \fB\-\-ytdl=yes\fP is used, -and the URL is detected by \fByoutube\-dl\fP, then the script will set this -property to the actual media URL. This property should be set only during -the \fBon_load\fP or \fBon_load_fail\fP hooks, otherwise it will have no effect -(or may do something implementation defined in the future). The property is -reset if playback of the current media ends. -.TP -.B \fBmedia\-title\fP -If the currently played file has a \fBtitle\fP tag, use that. -.sp -Otherwise, return the \fBfilename\fP property. -.TP -.B \fBfile\-format\fP -Symbolic name of the file format. In some cases, this is a comma\-separated -list of format names, e.g. mp4 is \fBmov,mp4,m4a,3gp,3g2,mj2\fP (the list -may grow in the future for any format). -.TP -.B \fBcurrent\-demuxer\fP -Name of the current demuxer. (This is useless.) -.sp -(Renamed from \fBdemuxer\fP\&.) -.TP -.B \fBstream\-path\fP -Filename (full path) of the stream layer filename. (This is probably -useless and is almost never different from \fBpath\fP\&.) -.TP -.B \fBstream\-pos\fP -Raw byte position in source stream. Technically, this returns the position -of the most recent packet passed to a decoder. -.TP -.B \fBstream\-end\fP -Raw end position in bytes in source stream. -.TP -.B \fBduration\fP -Duration of the current file in seconds. If the duration is unknown, the -property is unavailable. Note that the file duration is not always exactly -known, so this is an estimate. -.sp -This replaces the \fBlength\fP property, which was deprecated after the -mpv 0.9 release. (The semantics are the same.) -.TP -.B \fBavsync\fP -Last A/V synchronization difference. Unavailable if audio or video is -disabled. -.TP -.B \fBtotal\-avsync\-change\fP -Total A\-V sync correction done. Unavailable if audio or video is -disabled. -.TP -.B \fBdecoder\-frame\-drop\-count\fP -Video frames dropped by decoder, because video is too far behind audio (when -using \fB\-\-framedrop=decoder\fP). Sometimes, this may be incremented in other -situations, e.g. when video packets are damaged, or the decoder doesn\(aqt -follow the usual rules. Unavailable if video is disabled. -.sp -\fBdrop\-frame\-count\fP is a deprecated alias. -.TP -.B \fBframe\-drop\-count\fP -Frames dropped by VO (when using \fB\-\-framedrop=vo\fP). -.sp -\fBvo\-drop\-frame\-count\fP is a deprecated alias. -.TP -.B \fBmistimed\-frame\-count\fP -Number of video frames that were not timed correctly in display\-sync mode -for the sake of keeping A/V sync. This does not include external -circumstances, such as video rendering being too slow or the graphics -driver somehow skipping a vsync. It does not include rounding errors either -(which can happen especially with bad source timestamps). For example, -using the \fBdisplay\-desync\fP mode should never change this value from 0. -.TP -.B \fBvsync\-ratio\fP -For how many vsyncs a frame is displayed on average. This is available if -display\-sync is active only. For 30 FPS video on a 60 Hz screen, this will -be 2. This is the moving average of what actually has been scheduled, so -24 FPS on 60 Hz will never remain exactly on 2.5, but jitter depending on -the last frame displayed. -.TP -.B \fBvo\-delayed\-frame\-count\fP -Estimated number of frames delayed due to external circumstances in -display\-sync mode. Note that in general, mpv has to guess that this is -happening, and the guess can be inaccurate. -.TP -.B \fBpercent\-pos\fP (RW) -Position in current file (0\-100). The advantage over using this instead of -calculating it out of other properties is that it properly falls back to -estimating the playback position from the byte position, if the file -duration is not known. -.TP -.B \fBtime\-pos\fP (RW) -Position in current file in seconds. -.TP -.B \fBtime\-start\fP -Deprecated. Always returns 0. Before mpv 0.14, this used to return the start -time of the file (could affect e.g. transport streams). See -\fB\-\-rebase\-start\-time\fP option. -.TP -.B \fBtime\-remaining\fP -Remaining length of the file in seconds. Note that the file duration is not -always exactly known, so this is an estimate. -.TP -.B \fBaudio\-pts\fP -Current audio playback position in current file in seconds. Unlike time\-pos, -this updates more often than once per frame. For audio\-only files, it is -mostly equivalent to time\-pos, while for video\-only files this property is -not available. -.TP -.B \fBplaytime\-remaining\fP -\fBtime\-remaining\fP scaled by the current \fBspeed\fP\&. -.TP -.B \fBplayback\-time\fP (RW) -Position in current file in seconds. Unlike \fBtime\-pos\fP, the time is -clamped to the range of the file. (Inaccurate file durations etc. could -make it go out of range. Useful on attempts to seek outside of the file, -as the seek target time is considered the current position during seeking.) -.TP -.B \fBchapter\fP (RW) -Current chapter number. The number of the first chapter is 0. -.TP -.B \fBedition\fP (RW) -Current MKV edition number. Setting this property to a different value will -restart playback. The number of the first edition is 0. -.sp -Before mpv 0.31.0, this showed the actual edition selected at runtime, if -you didn\(aqt set the option or property manually. With mpv 0.31.0 and later, -this strictly returns the user\-set option or property value, and the -\fBcurrent\-edition\fP property was added to return the runtime selected -edition (this matters with \fB\-\-edition=auto\fP, the default). -.TP -.B \fBcurrent\-edition\fP -Currently selected edition. This property is unavailable if no file is -loaded, or the file has no editions. (Matroska files make a difference -between having no editions and a single edition, which will be reflected by -the property, although in practice it does not matter.) -.TP -.B \fBchapters\fP -Number of chapters. -.TP -.B \fBeditions\fP -Number of MKV editions. -.TP -.B \fBedition\-list\fP -List of editions, current entry marked. Currently, the raw property value -is useless. -.sp -This has a number of sub\-properties.

Use this to set the \fBedition\fP property. -Currently, this is the same as the edition index. -.TP -.B \fBedition\-list/N/default\fP -Whether this is the default edition. -.TP -.B \fBedition\-list/N/title\fP -Edition title as stored in the file. Not always available. -.UNINDENT -.sp -When querying the property with the client API using \fBMPV_FORMAT_NODE\fP, -or with Lua \fBmp.get_property_native\fP, this will return a mpv_node with -the following contents: -.INDENT 7.0 -.INDENT 3.5 -.sp -.nf -.ft C -MPV_FORMAT_NODE_ARRAY - MPV_FORMAT_NODE_MAP (for each edition) - "id" MPV_FORMAT_INT64 - "title" MPV_FORMAT_STRING - "default" MPV_FORMAT_FLAG -.ft P -.fi -.UNINDENT -.UNINDENT -.TP -.B \fBmetadata\fP -Metadata key/value pairs. -.sp -If the property is accessed with Lua\(aqs \fBmp.get_property_native\fP, this -returns a table with metadata keys mapping to metadata values.

It allows the same access -methods (using sub\-properties). -.sp -An example of this kind of metadata are the cropping parameters -added by \fB\-\-vf=lavfi=cropdetect\fP\&. -.TP -.B \fBaf\-metadata/<filter\-label>\fP -Equivalent to \fBvf\-metadata/<filter\-label>\fP, but for audio filters. -.TP -.B \fBidle\-active\fP -Returns \fByes\fP/true if no file is loaded, but the player is staying around -because of the \fB\-\-idle\fP option. -.sp -(Renamed from \fBidle\fP\&.) -.TP -.B \fBcore\-idle\fP -Whether the playback core is paused. This can differ from \fBpause\fP in -special situations, such as when the player pauses itself due to low -network cache. -.sp -This also returns \fByes\fP/true if playback is restarting or if nothing is -playing at all. In other words, it\(aqs only \fBno\fP/false if there\(aqs actually -video playing. (Behavior since mpv 0.7.0.) -.TP -.B \fBcache\-speed\fP -Current I/O read speed between the cache and the lower layer (like network). -This gives the number bytes per seconds over a 1 second window (using -the type \fBMPV_FORMAT_INT64\fP for the client API). -.sp -This is the same as \fBdemuxer\-cache\-state/raw\-input\-rate\fP\&. -.TP -.B \fBdemuxer\-cache\-duration\fP -Approximate duration of video buffered in the demuxer, in seconds. The -guess is very unreliable, and often the property will not be available -at all, even if data is buffered. -.TP -.B \fBdemuxer\-cache\-time\fP -Approximate time of video buffered in the demuxer, in seconds. Same as -\fBdemuxer\-cache\-duration\fP but returns the last timestamp of buffered -data in demuxer. -.TP -.B \fBdemuxer\-cache\-idle\fP -Whether the demuxer is idle, which means that the demuxer cache is filled -to the requested amount, and is currently not reading more data. -.TP -.B \fBdemuxer\-cache\-state\fP -Each entry in \fBseekable\-ranges\fP represents a region in the demuxer cache -that can be seeked to, with a \fBstart\fP and \fBend\fP fields containing the -respective timestamps. If there are multiple demuxers active, this only -returns information about the "main" demuxer, but might be changed in -future to return unified information about all demuxers. The ranges are in -arbitrary order. Often, ranges will overlap for a bit, before being joined. -In broken corner cases, ranges may overlap all over the place. -.sp -The end of a seek range is usually smaller than the value returned by the -\fBdemuxer\-cache\-time\fP property, because that property returns the guessed -buffering amount, while the seek ranges represent the buffered data that -can actually be used for cached seeking. -.sp -\fBbof\-cached\fP indicates whether the seek range with the lowest timestamp -points to the beginning of the stream (BOF). This implies you cannot seek -before this position at all. \fBeof\-cached\fP indicates whether the seek range -with the highest timestamp points to the end of the stream (EOF). If both -\fBbof\-cached\fP and \fBeof\-cached\fP are true, and there\(aqs only 1 cache range, -the entire stream is cached. -.sp -\fBfw\-bytes\fP is the number of bytes of packets buffered in the range -starting from the current decoding position. This is a rough estimate -(may not account correctly for various overhead), and stops at the -demuxer position (it ignores seek ranges after it). -.sp -\fBfile\-cache\-bytes\fP is the number of bytes stored in the file cache. This -includes all overhead, and possibly unused data (like pruned data). This -member is missing if the file cache wasn\(aqt enabled with -\fB\-\-cache\-on\-disk=yes\fP\&. -.sp -\fBcache\-end\fP is \fBdemuxer\-cache\-time\fP\&. Missing if unavailable. -.sp -\fBreader\-pts\fP is the approximate timestamp of the start of the buffered -range. Missing if unavailable. -.sp -\fBcache\-duration\fP is \fBdemuxer\-cache\-duration\fP\&. Missing if unavailable. -.sp -\fBraw\-input\-rate\fP is the estimated input rate of the network layer (or any -other byte\-oriented input layer) in bytes per second. May be inaccurate or -missing. -.sp -When querying the property with the client API using \fBMPV_FORMAT_NODE\fP, -or with Lua \fBmp.get_property_native\fP, this will return a mpv_node with -the following contents: -.INDENT 7.0 -.INDENT 3.5 -.sp -.nf -.ft C -MPV_FORMAT_NODE_MAP - "seekable\-ranges" MPV_FORMAT_NODE_ARRAY - MPV_FORMAT_NODE_MAP - "start" MPV_FORMAT_DOUBLE - "end" MPV_FORMAT_DOUBLE - "bof\-cached" MPV_FORMAT_FLAG - "eof\-cached" MPV_FORMAT_FLAG - "fw\-bytes" MPV_FORMAT_INT64 - "file\-cache\-bytes" MPV_FORMAT_INT64 - "cache\-end" MPV_FORMAT_DOUBLE - "reader\-pts" MPV_FORMAT_DOUBLE - "cache\-duration" MPV_FORMAT_DOUBLE - "raw\-input\-rate" MPV_FORMAT_INT64 -.ft P -.fi -.UNINDENT -.UNINDENT -.sp -Other fields (might be changed or removed in the future): -.INDENT 7.0 -.TP -.B \fBeof\fP -Whether the reader thread has hit the end of the file. -.TP -.B \fBunderrun\fP -Whether the reader thread could not satisfy a decoder\(aqs request for a -new packet. -.TP -.B \fBidle\fP -Whether the thread is currently not reading. -.TP -.B \fBtotal\-bytes\fP -Sum of packet bytes (plus some overhead estimation) of the entire packet -queue, including cached seekable ranges. -.UNINDENT -.TP -.B \fBdemuxer\-via\-network\fP -Whether the stream demuxed via the main demuxer is most likely played via -network. What constitutes "network" is not always clear, might be used for -other types of untrusted streams, could be wrong in certain cases, and its -definition might be changing. Also, external files (like separate audio -files or streams) do not influence the value of this property (currently). -.TP -.B \fBdemuxer\-start\-time\fP -The start time reported by the demuxer in fractional seconds. -.TP -.B \fBpaused\-for\-cache\fP -Whether playback is paused because of waiting for the cache. -.TP -.B \fBcache\-buffering\-state\fP -The percentage (0\-100) of the cache fill status until the player will -unpause (related to \fBpaused\-for\-cache\fP). -.TP -.B \fBeof\-reached\fP -Whether the end of playback was reached. Note that this is usually -interesting only if \fB\-\-keep\-open\fP is enabled, since otherwise the player -will immediately play the next file (or exit or enter idle mode), and in -these cases the \fBeof\-reached\fP property will logically be cleared -immediately after it\(aqs set. -.TP -.B \fBseeking\fP -Whether the player is currently seeking, or otherwise trying to restart -playback. (It\(aqs possible that it returns \fByes\fP/true while a file is -loaded. This is because the same underlying code is used for seeking and -resyncing.) -.TP -.B \fBmixer\-active\fP -Whether the audio mixer is active. -.sp -This option is relatively useless. Before mpv 0.18.1, it could be used to -infer behavior of the \fBvolume\fP property. -.TP -.B \fBao\-volume\fP (RW) -System volume. This property is available only if mpv audio output is -currently active, and only if the underlying implementation supports volume -control. What this option does depends on the API.

This can easily contain bogus values. For videos that use -modern container formats or video codecs, this will often be incorrect. -.sp -(Renamed from \fBfps\fP\&.) -.TP -.B \fBestimated\-vf\-fps\fP -Estimated/measured FPS of the video filter chain output. (If no filters -are used, this corresponds to decoder output.) This uses the average of -the 10 past frame durations to calculate the FPS. It will be inaccurate -if frame\-dropping is involved (such as when framedrop is explicitly -enabled, or after precise seeking). Files with imprecise timestamps (such -as Matroska) might lead to unstable results. -.TP -.B \fBwindow\-scale\fP (RW) -Window size multiplier. Setting this will resize the video window to the -values contained in \fBdwidth\fP and \fBdheight\fP multiplied with the value -set with this property. Setting \fB1\fP will resize to original video size -(or to be exact, the size the video filters output). \fB2\fP will set the -double size, \fB0.5\fP halves the size. -.sp -Note that setting a value identical to its previous value will not resize -the window. That\(aqs because this property mirrors the \fBwindow\-scale\fP -option, and setting an option to its previous value is ignored. If this -value is set while the window is in a fullscreen, the multiplier is not -applied until the window is taken out of that state. Writing this property -to a maximized window can unmaximize the window depending on the OS and -window manager.

This -has the same value as \fBwindow\-scale\fP if the window size was not changed -since setting the option, and the window size was not restricted in other -ways. If the window is fullscreened, this will return the scale value -calculated from the last non\-fullscreen size of the window. The property -is unavailable if no video is active. -.sp -When setting this property in the fullscreen or maximized state, the behavior -is the same as window\-scale.

Might not be supported by all VOs. -.TP -.B \fBdisplay\-names\fP -Names of the displays that the mpv window covers. On X11, these -are the xrandr names (LVDS1, HDMI1, DP1, VGA1, etc.). On Windows, these -are the GDI names (\e.DISPLAY1, \e.DISPLAY2, etc.) and the first display -in the list will be the one that Windows considers associated with the -window (as determined by the MonitorFromWindow API.)

Only available if display\-sync mode (as selected by -\fB\-\-video\-sync\fP) is active. -.TP -.B \fBvsync\-jitter\fP -Estimated deviation factor of the vsync duration. -.TP -.B \fBdisplay\-width\fP, \fBdisplay\-height\fP -The current display\(aqs horizontal and vertical resolution in pixels. Whether -or not these values update as the mpv window changes displays depends on -the windowing backend. It may not be available on all platforms. -.TP -.B \fBdisplay\-hidpi\-scale\fP -The HiDPI scale factor as reported by the windowing backend. If no VO is -active, or if the VO does not report a value, this property is unavailable. -It may be saner to report an absolute DPI, however, this is the way HiDPI -support is implemented on most OS APIs.

Text subtitles in -other formats are converted. For native ASS subtitles, events that do -not contain any text (but vector drawings etc.) are not filtered out. If -multiple events match with the current playback time, they are concatenated -with line breaks.

If there\(aqs multiple current -subtitles, returns the first start time. If no current subtitle is present -null is returned instead. -.TP -.B \fBsecondary\-sub\-start\fP -Same as \fBsub\-start\fP, but for the secondary subtitles. -.TP -.B \fBsub\-end\fP -The current subtitle end time (in seconds).

The first entry is on position 0. Writing to -this property may start playback at the new position. -.sp -In some cases, this is not necessarily the currently playing file. See -explanation of \fBcurrent\fP and \fBplaying\fP flags in \fBplaylist\fP\&. -.sp -If there the playlist is empty, or if it\(aqs non\-empty, but no entry is -"current", this property returns \-1. Likewise, writing \-1 will put the -player into idle mode (or exit playback if idle mode is not enabled). If an -out of range index is written to the property, this behaves as if writing \-1. -(Before mpv 0.33.0, instead of returning \-1, this property was unavailable -if no playlist entry was current.) -.sp -Writing the current value back to the property is subject to change. -Currently, it will restart playback of the playlist entry.

Use the -\fBplaylist\-play\-index\fP command to get guaranteed behavior. -.TP -.B \fBplaylist\-pos\-1\fP (RW) -Same as \fBplaylist\-pos\fP, but 1\-based. -.TP -.B \fBplaylist\-current\-pos\fP (RW) -Index of the "current" item on playlist. This usually, but not necessarily, -the currently playing item (see \fBplaylist\-playing\-pos\fP). Depending on the -exact internal state of the player, it may refer to the playlist item to -play next, or the playlist item used to determine what to play next. -.sp -For reading, this is exactly the same as \fBplaylist\-pos\fP\&. -.sp -For writing, this \fIonly\fP sets the position of the "current" item, without -stopping playback of the current file (or starting playback, if this is done -in idle mode). Use \-1 to remove the current flag. -.sp -This property is only vaguely useful. If set during playback, it will -typically cause the playlist entry \fIafter\fP it to be played next. Another -possibly odd observable state is that if \fBplaylist\-next\fP is run during -playback, this property is set to the playlist entry to play next (unlike -the previous case). There is an internal flag that decides whether the -current playlist entry or the next one should be played, and this flag is -currently inaccessible for API users. (Whether this behavior will kept is -possibly subject to change.) -.TP -.B \fBplaylist\-playing\-pos\fP -Index of the "playing" item on playlist. A playlist item is "playing" if -it\(aqs being loaded, actually playing, or being unloaded. This property is set -during the \fBMPV_EVENT_START_FILE\fP (\fBstart\-file\fP) and the -\fBMPV_EVENT_START_END\fP (\fBend\-file\fP) events. Outside of that, it returns -\-1. If the playlist entry was somehow removed during playback, but playback -hasn\(aqt stopped yet, or is in progress of being stopped, it also returns \-1. -(This can happen at least during state transitions.) -.sp -In the "playing" state, this is usually the same as \fBplaylist\-pos\fP, except -during state changes, or if \fBplaylist\-current\-pos\fP was written explicitly. -.TP -.B \fBplaylist\-count\fP -Number of total playlist entries. -.TP -.B \fBplaylist\fP -Playlist, current entry marked.

For -example, if you set \fBaid=5\fP, and the currently played file contains no -audio track with ID 5, the \fBaid\fP property will return \fBno\fP\&. -.sp -Before mpv 0.31.0, you could set existing tracks at runtime only. -.TP -.B \fBdisplay\-fps\fP -This inconsistent behavior is deprecated. Post\-deprecation, the reported -value and the option value are cleanly separated (\fBoverride\-display\-fps\fP -for the option value). -.TP -.B \fBvf\fP, \fBaf\fP -If you set the properties during playback, and the filter chain fails to -reinitialize, the option will be set, but the runtime filter chain does not -change. On the other hand, the next video to be played will fail, because -the initial filter chain cannot be created. -.sp -This behavior changed in mpv 0.31.0. Before this, the new value was rejected -\fIiff\fP a video (for \fBvf\fP) or an audio (for \fBaf\fP) track was active. If -playback was not active, the behavior was the same as the current one. -.TP -.B \fBplaylist\fP -The property is read\-only and returns the current internal playlist. The -option is for loading playlist during command line parsing. For client API -uses, you should use the \fBloadlist\fP command instead. -.TP -.B \fBprofile\fP, \fBinclude\fP -These are write\-only, and will perform actions as they are written to, -exactly as if they were used on the mpv CLI commandline. Their only use is -when using libmpv before \fBmpv_initialize()\fP, which in turn is probably -only useful in encoding mode. Normal libmpv users should use other -mechanisms, such as the \fBapply\-profile\fP command, and the -\fBmpv_load_config_file\fP API function. Avoid these properties. -.UNINDENT -.SS Property Expansion -.sp -All string arguments to input commands as well as certain options (like -\fB\-\-term\-playing\-msg\fP) are subject to property expansion. Note that property -expansion does not work in places where e.g. numeric parameters are expected. -(For example, the \fBadd\fP command does not do property expansion.

If retrieving the property -fails, expand to an error string. (Use \fB${NAME:}\fP with a trailing -\fB:\fP to expand to an empty string instead.) -If \fBNAME\fP is prefixed with \fB=\fP, expand to the raw value of the property -(see section below). -.TP -.B \fB${NAME:STR}\fP -Expands to the value of the property \fBNAME\fP, or \fBSTR\fP if the -property cannot be retrieved. \fBSTR\fP is expanded recursively. -.TP -.B \fB${?NAME:STR}\fP -Expands to \fBSTR\fP (recursively) if the property \fBNAME\fP is available. -.TP -.B \fB${!NAME:STR}\fP -Expands to \fBSTR\fP (recursively) if the property \fBNAME\fP cannot be -retrieved. -.TP -.B \fB${?NAME==VALUE:STR}\fP -Expands to \fBSTR\fP (recursively) if the property \fBNAME\fP expands to a -string equal to \fBVALUE\fP\&. You can prefix \fBNAME\fP with \fB=\fP in order to -compare the raw value of a property (see section below). If the property -is unavailable, or other errors happen when retrieving it, the value is -never considered equal. -Note that \fBVALUE\fP can\(aqt contain any of the characters \fB:\fP or \fB}\fP\&. -Also, it is possible that escaping with \fB"\fP or \fB%\fP might be added in -the future, should the need arise. -.TP -.B \fB${!NAME==VALUE:STR}\fP -Same as with the \fB?\fP variant, but \fBSTR\fP is expanded if the value is -not equal. (Using the same semantics as with \fB?\fP\&.) -.TP -.B \fB$$\fP -Expands to \fB$\fP\&. -.TP -.B \fB$}\fP -Expands to \fB}\fP\&. (To produce this character inside recursive -expansion.) -.TP -.B \fB$>\fP -Disable property expansion and special handling of \fB$\fP for the rest -of the string. -.UNINDENT -.sp -In places where property expansion is allowed, C\-style escapes are often -accepted as well.

It is possible to retrieve an unformatted -(raw) value from a property by prefixing its name with \fB=\fP\&. These raw values -can be parsed by other programs and follow the same conventions as the options -associated with the properties. -.INDENT 0.0 -.INDENT 3.5 -.IP "Examples" -.INDENT 0.0 -.IP \(bu 2 -\fB${time\-pos}\fP expands to \fB00:14:23\fP (if playback position is at 14 -minutes 23 seconds) -.IP \(bu 2 -\fB${=time\-pos}\fP expands to \fB863.4\fP (same time, plus 400 milliseconds \- -milliseconds are normally not shown in the formatted case) -.UNINDENT -.UNINDENT -.UNINDENT -.sp -Sometimes, the difference in amount of information carried by raw and formatted -property values can be rather big. In some cases, raw values have more -information, like higher precision than seconds with \fBtime\-pos\fP\&. Sometimes -it is the other way around, e.g. \fBaid\fP shows track title and language in the -formatted case, but only the track number if it is raw. -.SH ON SCREEN CONTROLLER -.sp -The On Screen Controller (short: OSC) is a minimal GUI integrated with mpv to -offer basic mouse\-controllability.

If set to \fByes\fP, -default seeking mode is used (usually keyframes, but player defaults and -heuristics can change it to exact). If set to \fBno\fP, exact seeking on -mouse drags will be used instead. Keyframes are preferred, but exact seeks -may be useful in cases where keyframes cannot be found.

If this option is set, -the osc may overwrite the \fB\-\-video\-margin\-ratio\-*\fP options, even if the -user has set them. (It will not overwrite them if all of them are set to -default values.) Additionally, \fBvisibility\fP must be set to \fBalways\fP\&. -Otherwise, this option does nothing. -.sp -Currently, this is supported for the \fBbottombar\fP and \fBtopbar\fP layout -only. The other layouts do not change if this option is set. Separately, -if window controls are present (see below), they will be affected -regardless of which osc layout is in use. -.sp -The border is static and appears even if the OSC is configured to appear -only on mouse interaction. If the OSC is invisible, the border is simply -filled with the background color (black by default). -.sp -This currently still makes the OSC overlap with subtitles (if the -\fB\-\-sub\-use\-margins\fP option is set to \fByes\fP, the default).

(See \fI\%Script location\fP\&.) -.sp -mpv provides the built\-in module \fBmp\fP, which contains functions to send -commands to the mpv core and to retrieve information about playback state, user -settings, file information, and so on. -.sp -These scripts can be used to control mpv in a similar way to slave mode. -Technically, the Lua code uses the client API internally. -.SS Example -.sp -A script which leaves fullscreen mode when the player is paused: -.INDENT 0.0 -.INDENT 3.5 -.sp -.nf -.ft C -function on_pause_change(name, value) - if value == true then - mp.set_property("fullscreen", "no") - end -end -mp.observe_property("pause", "bool", on_pause_change) -.ft P -.fi -.UNINDENT -.UNINDENT -.SS Script location -.sp -Scripts can be passed to the \fB\-\-script\fP option, and are automatically loaded -from the \fBscripts\fP subdirectory of the mpv configuration directory (usually -\fB~/.config/mpv/scripts/\fP). -.sp -A script can be a single file. The file extension is used to select the -scripting backend to use for it. For Lua, it is \fB\&.lua\fP\&. If the extension is -not recognized, an error is printed. (If an error happens, the extension is -either mistyped, or the backend was not compiled into your mpv binary.) -.sp -mpv internally loads the script\(aqs name by stripping the \fB\&.lua\fP extension and -replacing all nonalphanumeric characters with \fB_\fP\&. E.g., \fBmy\-tools.lua\fP -becomes \fBmy_tools\fP\&. If there are several scripts with the same name, it is -made unique by appending a number. This is the name returned by -\fBmp.get_script_name()\fP\&. -.sp -Entries with \fB\&.disable\fP extension are always ignored. -.sp -If a script is a directory (either if a directory is passed to \fB\-\-script\fP, -or any sub\-directories in the script directory, such as for example -\fB~/.config/mpv/scripts/something/\fP), then the directory represents a single -script. The player will try to load a file named \fBmain.x\fP, where \fBx\fP is -replaced with the file extension. For example, if \fBmain.lua\fP exists, it is -loaded with the Lua scripting backend. -.sp -You must not put any other files or directories that start with \fBmain.\fP into -the script\(aqs top level directory. If the script directory contains for example -both \fBmain.lua\fP and \fBmain.js\fP, only one of them will be loaded (and which -one depends on mpv internals that may change any time). Likewise, if there is -for example \fBmain.foo\fP, your script will break as soon as mpv adds a backend -that uses the \fB\&.foo\fP file extension. -.sp -mpv also appends the top level directory of the script to the start of Lua\(aqs -package path so you can import scripts from there too. Be aware that this will -shadow Lua libraries that use the same package path. (Single file scripts do not -include mpv specific directory the Lua package path. This was silently changed -in mpv 0.32.0.) -.sp -Using a script directory is the recommended way to package a script that -consists of multiple source files, or requires other files (you can use -\fBmp.get_script_directory()\fP to get the location and e.g. load data files). -.sp -Making a script a git repository, basically a repository which contains a -\fBmain.lua\(ga\fP file in the root directory, makes scripts easily updateable -(without the dangers of auto\-updates). Another suggestion is to use git -submodules to share common files or libraries. -.SS Details on the script initialization and lifecycle -.sp -Your script will be loaded by the player at program start from the \fBscripts\fP -configuration subdirectory, or from a path specified with the \fB\-\-script\fP -option. Some scripts are loaded internally (like \fB\-\-osc\fP). Each script runs in -its own thread. Your script is first run "as is", and once that is done, the event loop -is entered. This event loop will dispatch events received by mpv and call your -own event handlers which you have registered with \fBmp.register_event\fP, or -timers added with \fBmp.add_timeout\fP or similar. Note that since the -script starts execution concurrently with player initialization, some properties -may not be populated with meaningful values until the relevant subsystems have -initialized. -.sp -When the player quits, all scripts will be asked to terminate. This happens via -a \fBshutdown\fP event, which by default will make the event loop return. If your -script got into an endless loop, mpv will probably behave fine during playback, -but it won\(aqt terminate when quitting, because it\(aqs waiting on your script. -.sp -Internally, the C code will call the Lua function \fBmp_event_loop\fP after -loading a Lua script. This function is normally defined by the default prelude -loaded before your script (see \fBplayer/lua/defaults.lua\fP in the mpv sources). -The event loop will wait for events and dispatch events registered with -\fBmp.register_event\fP\&. It will also handle timers added with \fBmp.add_timeout\fP -and similar (by waiting with a timeout). -.sp -Since mpv 0.6.0, the player will wait until the script is fully loaded before -continuing normal operation. The player considers a script as fully loaded as -soon as it starts waiting for mpv events (or it exits). In practice this means -the player will more or less hang until the script returns from the main chunk -(and \fBmp_event_loop\fP is called), or the script calls \fBmp_event_loop\fP or -\fBmp.dispatch_events\fP directly. This is done to make it possible for a script -to fully setup event handlers etc. before playback actually starts. In older -mpv versions, this happened asynchronously. With mpv 0.29.0, this changes -slightly, and it merely waits for scripts to be loaded in this manner before -starting playback as part of the player initialization phase. Scripts run though -initialization in parallel. This might change again. -.SS mp functions -.sp -The \fBmp\fP module is preloaded, although it can be loaded manually with -\fBrequire \(aqmp\(aq\fP\&. It provides the core client API. -.INDENT 0.0 -.TP -.B \fBmp.command(string)\fP -Run the given command. This is similar to the commands used in input.conf. -See \fI\%List of Input Commands\fP\&. -.sp -By default, this will show something on the OSD (depending on the command), -as if it was used in \fBinput.conf\fP\&. See \fI\%Input Command Prefixes\fP how -to influence OSD usage per command. -.sp -Returns \fBtrue\fP on success, or \fBnil, error\fP on error. -.TP -.B \fBmp.commandv(arg1, arg2, ...)\fP -Similar to \fBmp.command\fP, but pass each command argument as separate -parameter. This has the advantage that you don\(aqt have to care about -quoting and escaping in some cases. -.sp -Example: -.INDENT 7.0 -.INDENT 3.5 -.sp -.nf -.ft C -mp.command("loadfile " .. filename .. " append") -mp.commandv("loadfile", filename, "append") -.ft P -.fi -.UNINDENT -.UNINDENT -.sp -These two commands are equivalent, except that the first version breaks -if the filename contains spaces or certain special characters. -.sp -Note that properties are \fInot\fP expanded. You can use either \fBmp.command\fP, -the \fBexpand\-properties\fP prefix, or the \fBmp.get_property\fP family of -functions. -.sp -Unlike \fBmp.command\fP, this will not use OSD by default either (except -for some OSD\-specific commands). -.TP -.B \fBmp.command_native(table [,def])\fP -Similar to \fBmp.commandv\fP, but pass the argument list as table. This has -the advantage that in at least some cases, arguments can be passed as -native types. It also allows you to use named argument. -.sp -If the table is an array, each array item is like an argument in -\fBmp.commandv()\fP (but can be a native type instead of a string). -.sp -If the table contains string keys, it\(aqs interpreted as command with named -arguments. This requires at least an entry with the key \fBname\fP to be -present, which must be a string, and contains the command name. The special -entry \fB_flags\fP is optional, and if present, must be an array of -\fI\%Input Command Prefixes\fP to apply. All other entries are interpreted as -arguments. -.sp -Returns a result table on success (usually empty), or \fBdef, error\fP on -error. \fBdef\fP is the second parameter provided to the function, and is -nil if it\(aqs missing. -.TP -.B \fBmp.command_native_async(table [,fn])\fP -Like \fBmp.command_native()\fP, but the command is ran asynchronously (as far -as possible), and upon completion, fn is called. fn has three arguments: -\fBfn(success, result, error)\fP: -.INDENT 7.0 -.INDENT 3.5 -.INDENT 0.0 -.INDENT 3.5 -.INDENT 0.0 -.TP -.B \fBsuccess\fP -Always a Boolean and is true if the command was successful, -otherwise false. -.UNINDENT -.UNINDENT -.UNINDENT -.INDENT 0.0 -.TP -.B \fBresult\fP -The result value (can be nil) in case of success, nil otherwise (as -returned by \fBmp.command_native()\fP). -.TP -.B \fBerror\fP -The error string in case of an error, nil otherwise. -.UNINDENT -.UNINDENT -.UNINDENT -.sp -Returns a table with undefined contents, which can be used as argument for -\fBmp.abort_async_command\fP\&. -.sp -If starting the command failed for some reason, \fBnil, error\fP is returned, -and \fBfn\fP is called indicating failure, using the same error value. -.TP -.B \fBmp.abort_async_command(t)\fP -Abort a \fBmp.command_native_async\fP call. The argument is the return value -of that command (which starts asynchronous execution of the command). -Whether this works and how long it takes depends on the command and the -situation. The abort call itself is asynchronous. Does not return anything. -.TP -.B \fBmp.get_property(name [,def])\fP -Return the value of the given property as string. These are the same -properties as used in input.conf. See \fI\%Properties\fP for a list of -properties. The returned string is formatted similar to \fB${=name}\fP -(see \fI\%Property Expansion\fP). -.sp -Returns the string on success, or \fBdef, error\fP on error. \fBdef\fP is the -second parameter provided to the function, and is nil if it\(aqs missing. -.TP -.B \fBmp.get_property_osd(name [,def])\fP -Similar to \fBmp.get_property\fP, but return the property value formatted for -OSD. This is the same string as printed with \fB${name}\fP when used in -input.conf. -.sp -Returns the string on success, or \fBdef, error\fP on error. \fBdef\fP is the -second parameter provided to the function, and is an empty string if it\(aqs -missing. Unlike \fBget_property()\fP, assigning the return value to a variable -will always result in a string. -.TP -.B \fBmp.get_property_bool(name [,def])\fP -Similar to \fBmp.get_property\fP, but return the property value as Boolean. -.sp -Returns a Boolean on success, or \fBdef, error\fP on error. -.TP -.B \fBmp.get_property_number(name [,def])\fP -Similar to \fBmp.get_property\fP, but return the property value as number. -.sp -Note that while Lua does not distinguish between integers and floats, -mpv internals do. This function simply request a double float from mpv, -and mpv will usually convert integer property values to float. -.sp -Returns a number on success, or \fBdef, error\fP on error. -.TP -.B \fBmp.get_property_native(name [,def])\fP -Similar to \fBmp.get_property\fP, but return the property value using the best -Lua type for the property. Most time, this will return a string, Boolean, -or number. Some properties (for example \fBchapter\-list\fP) are returned as -tables. -.sp -Returns a value on success, or \fBdef, error\fP on error. Note that \fBnil\fP -might be a possible, valid value too in some corner cases. -.TP -.B \fBmp.set_property(name, value)\fP -Set the given property to the given string value. See \fBmp.get_property\fP -and \fI\%Properties\fP for more information about properties. -.sp -Returns true on success, or \fBnil, error\fP on error. -.TP -.B \fBmp.set_property_bool(name, value)\fP -Similar to \fBmp.set_property\fP, but set the given property to the given -Boolean value. -.TP -.B \fBmp.set_property_number(name, value)\fP -Similar to \fBmp.set_property\fP, but set the given property to the given -numeric value. -.sp -Note that while Lua does not distinguish between integers and floats, -mpv internals do. This function will test whether the number can be -represented as integer, and if so, it will pass an integer value to mpv, -otherwise a double float. -.TP -.B \fBmp.set_property_native(name, value)\fP -Similar to \fBmp.set_property\fP, but set the given property using its native -type. -.sp -Since there are several data types which cannot represented natively in -Lua, this might not always work as expected. For example, while the Lua -wrapper can do some guesswork to decide whether a Lua table is an array -or a map, this would fail with empty tables. Also, there are not many -properties for which it makes sense to use this, instead of -\fBset_property\fP, \fBset_property_bool\fP, \fBset_property_number\fP\&. -For these reasons, this function should probably be avoided for now, except -for properties that use tables natively. -.TP -.B \fBmp.get_time()\fP -Return the current mpv internal time in seconds as a number. This is -basically the system time, with an arbitrary offset. -.TP -.B \fBmp.add_key_binding(key, name|fn [,fn [,flags]])\fP -Register callback to be run on a key binding. The binding will be mapped to -the given \fBkey\fP, which is a string describing the physical key. This uses -the same key names as in input.conf, and also allows combinations -(e.g. \fBctrl+a\fP). If the key is empty or \fBnil\fP, no physical key is -registered, but the user still can create own bindings (see below). -.sp -After calling this function, key presses will cause the function \fBfn\fP to -be called (unless the user remapped the key with another binding). -.sp -The \fBname\fP argument should be a short symbolic string. It allows the user -to remap the key binding via input.conf using the \fBscript\-message\fP -command, and the name of the key binding (see below for -an example). The name should be unique across other bindings in the same -script \- if not, the previous binding with the same name will be -overwritten. You can omit the name, in which case a random name is generated -internally. (Omitting works as follows: either pass \fBnil\fP for \fBname\fP, -or pass the \fBfn\fP argument in place of the name. The latter is not -recommended and is handled for compatibility only.) -.sp -The last argument is used for optional flags. This is a table, which can -have the following entries: -.INDENT 7.0 -.INDENT 3.5 -.INDENT 0.0 -.TP -.B \fBrepeatable\fP -If set to \fBtrue\fP, enables key repeat for this specific binding. -.TP -.B \fBcomplex\fP -If set to \fBtrue\fP, then \fBfn\fP is called on both key up and down -events (as well as key repeat, if enabled), with the first -argument being a table. This table has the following entries (and -may contain undocumented ones): -.INDENT 7.0 -.INDENT 3.5 -.INDENT 0.0 -.TP -.B \fBevent\fP -Set to one of the strings \fBdown\fP, \fBrepeat\fP, \fBup\fP or -\fBpress\fP (the latter if key up/down can\(aqt be tracked). -.TP -.B \fBis_mouse\fP -Boolean Whether the event was caused by a mouse button. -.TP -.B \fBkey_name\fP -The name of they key that triggered this, or \fBnil\fP if -invoked artificially. If the key name is unknown, it\(aqs an -empty string. -.TP -.B \fBkey_text\fP -Text if triggered by a text key, otherwise \fBnil\fP\&.

(\fBmp.add_key_binding\fP overwrites default key bindings only, -but not those by the user\(aqs input.conf.) -.TP -.B \fBmp.remove_key_binding(name)\fP -Remove a key binding added with \fBmp.add_key_binding\fP or -\fBmp.add_forced_key_binding\fP\&. Use the same name as you used when adding -the bindings. It\(aqs not possible to remove bindings for which you omitted -the name. -.TP -.B \fBmp.register_event(name, fn)\fP -Call a specific function when an event happens. The event name is a string, -and the function fn is a Lua function value. -.sp -Some events have associated data. This is put into a Lua table and passed -as argument to fn. The Lua table by default contains a \fBname\fP field, -which is a string containing the event name. If the event has an error -associated, the \fBerror\fP field is set to a string describing the error, -on success it\(aqs not set. -.sp -If multiple functions are registered for the same event, they are run in -registration order, which the first registered function running before all -the other ones. -.sp -Returns true if such an event exists, false otherwise. -.sp -See \fI\%Events\fP and \fI\%List of events\fP for details. -.TP -.B \fBmp.unregister_event(fn)\fP -Undo \fBmp.register_event(..., fn)\fP\&. This removes all event handlers that -are equal to the \fBfn\fP parameter. This uses normal Lua \fB==\fP comparison, -so be careful when dealing with closures. -.TP -.B \fBmp.observe_property(name, type, fn)\fP -Watch a property for changes. If the property \fBname\fP is changed, then -the function \fBfn(name)\fP will be called. \fBtype\fP can be \fBnil\fP, or be -set to one of \fBnone\fP, \fBnative\fP, \fBbool\fP, \fBstring\fP, or \fBnumber\fP\&. -\fBnone\fP is the same as \fBnil\fP\&. For all other values, the new value of -the property will be passed as second argument to \fBfn\fP, using -\fBmp.get_property_<type>\fP to retrieve it. This means if \fBtype\fP is for -example \fBstring\fP, \fBfn\fP is roughly called as in -\fBfn(name, mp.get_property_string(name))\fP\&. -.sp -If possible, change events are coalesced. If a property is changed a bunch -of times in a row, only the last change triggers the change function. (The -exact behavior depends on timing and other things.) -.sp -If a property is unavailable, or on error, the value argument to \fBfn\fP is -\fBnil\fP\&. (The \fBobserve_property()\fP call always succeeds, even if a -property does not exist.) -.sp -In some cases the function is not called even if the property changes. -This depends on the property, and it\(aqs a valid feature request to ask for -better update handling of a specific property. -.sp -If the \fBtype\fP is \fBnone\fP or \fBnil\fP, sporadic property change events are -possible. This means the change function \fBfn\fP can be called even if the -property doesn\(aqt actually change. -.sp -You always get an initial change notification.

These needs to unique to avoid collisions with other scripts. -Defaults to \fBmp.get_script_name()\fP if the parameter is \fBnil\fP or missing. -.sp -The \fBon_update\fP parameter enables run\-time updates of all matching option -values via the \fBscript\-opts\fP option/property. If any of the matching -options changes, the values in the \fBtable\fP (which was originally passed to -the function) are changed, and \fBon_update(list)\fP is called. \fBlist\fP is -a table where each updated option has a \fBlist[option_name] = true\fP entry. -There is no initial \fBon_update()\fP call.

This is true also for -intervals \- which also never call back twice at the same event loop iteration. -.sp -Additionally, timers are processed after the event queue is empty, so it\(aqs valid -to use \fBsetTimeout(fn)\fP as a one\-time idle observer. -.SS CommonJS modules and \fBrequire(id)\fP -.sp -CommonJS Modules are a standard system where scripts can export common functions -for use by other scripts. Specifically, a module is a script which adds -properties (functions, etc) to its pre\-existing \fBexports\fP object, which -another script can access with \fBrequire(module\-id)\fP\&. This runs the module and -returns its \fBexports\fP object. Further calls to \fBrequire\fP for the same module -will return its cached \fBexports\fP object without running the module again. -.sp -Modules and \fBrequire\fP are supported, standard compliant, and generally similar -to node.js. However, most node.js modules won\(aqt run due to missing modules such -as \fBfs\fP, \fBprocess\fP, etc, but some node.js modules with minimal dependencies -do work. In general, this is for mpv modules and not a node.js replacement. -.sp -A \fB\&.js\fP file extension is always added to \fBid\fP, e.g. \fBrequire("./foo")\fP -will load the file \fB\&./foo.js\fP and return its \fBexports\fP object. -.sp -An id which starts with \fB\&./\fP or \fB\&../\fP is relative to the script or module -which \fBrequire\fP it. Otherwise it\(aqs considered a top\-level id (CommonJS term). -.sp -Top\-level id is evaluated as absolute filesystem path if possible, e.g. \fB/x/y\fP -or \fB~/x\fP\&. Otherwise it\(aqs considered a global module id and searched according -to \fBmp.module_paths\fP in normal array order, e.g. \fBrequire("x")\fP tries to -load \fBx.js\fP at one of the array paths, and id \fBfoo/x\fP tries to load \fBx.js\fP -inside dir \fBfoo\fP at one of the paths. -.sp -The \fBmp.module_paths\fP array is empty by default except for scripts which are -loaded as a directory where it contains one item \- \fB<directory>/modules/\fP . -The array may be updated from a script (or using custom init \- see below) which -will affect future calls to \fBrequire\fP for global module id\(aqs which are not -already loaded/cached. -.sp -No \fBglobal\fP variable, but a module\(aqs \fBthis\fP at its top lexical scope is the -global object \- also in strict mode. If you have a module which needs \fBglobal\fP -as the global object, you could do \fBthis.global = this;\fP before \fBrequire\fP\&. -.sp -Functions and variables declared at a module don\(aqt pollute the global object. -.SS Custom initialization -.sp -After mpv initializes the JavaScript environment for a script but before it -loads the script \- it tries to run the file \fBinit.js\fP at the root of the mpv -configuration directory. Code at this file can update the environment further -for all scripts. E.g. if it contains \fBmp.module_paths.push("/foo")\fP then -\fBrequire\fP at all scripts will search global module id\(aqs also at \fB/foo\fP -(do NOT do \fBmp.module_paths = ["/foo"];\fP because this will remove existing -paths \- like \fB<script\-dir>/modules\fP for scripts which load from a directory). -.sp -The custom\-init file is ignored if mpv is invoked with \fB\-\-no\-config\fP\&. -.sp -Before mpv 0.34, the file name was \fB\&.init.js\fP (with dot) at the same dir. -.SS The event loop -.sp -The event loop poll/dispatch mpv events as long as the queue is not empty, then -processes the timers, then waits for the next event, and repeats this forever. -.sp -You could put this code at your script to replace the built\-in event loop, and -also print every event which mpv sends to your script: -.INDENT 0.0 -.INDENT 3.5 -.sp -.nf -.ft C -function mp_event_loop() { - var wait = 0; - do { - var e = mp.wait_event(wait); - dump(e); // there could be a lot of prints... - if (e.event != "none") { - mp.dispatch_event(e); - wait = 0; - } else { - wait = mp.process_timers() / 1000; - if (wait != 0) { - mp.notify_idle_observers(); - wait = mp.peek_timers_wait() / 1000; - } - } - } while (mp.keep_running); -} -.ft P -.fi -.UNINDENT -.UNINDENT -.sp -\fBmp_event_loop\fP is a name which mpv tries to call after the script loads. -The internal implementation is similar to this (without \fBdump\fP though..). -.sp -\fBe = mp.wait_event(wait)\fP returns when the next mpv event arrives, or after -\fBwait\fP seconds if positive and no mpv events arrived. \fBwait\fP value of 0 -returns immediately (with \fBe.event == "none"\fP if the queue is empty). -.sp -\fBmp.dispatch_event(e)\fP calls back the handlers registered for \fBe.event\fP, -if there are such (event handlers, property observers, script messages, etc). -.sp -\fBmp.process_timers()\fP calls back the already\-added, non\-canceled due timers, -and returns the duration in ms till the next due timer (possibly 0), or \-1 if -there are no pending timers. Must not be called recursively. -.sp -\fBmp.notify_idle_observers()\fP calls back the idle observers, which we do when -we\(aqre about to sleep (wait != 0), but the observers may add timers or take -non\-negligible duration to complete, so we re\-calculate \fBwait\fP afterwards. -.sp -\fBmp.peek_timers_wait()\fP returns the same values as \fBmp.process_timers()\fP -but without doing anything. Invalid result if called from a timer callback. -.sp -Note: \fBexit()\fP is also registered for the \fBshutdown\fP event, and its -implementation is a simple \fBmp.keep_running = false\fP\&. -.SH JSON IPC -.sp -mpv can be controlled by external programs using the JSON\-based IPC protocol. -It can be enabled by specifying the path to a unix socket or a named pipe using -the option \fB\-\-input\-ipc\-server\fP\&. Clients can connect to this socket and send -commands to the player or receive events from it. -.sp -\fBWARNING:\fP -.INDENT 0.0 -.INDENT 3.5 -This is not intended to be a secure network protocol. It is explicitly -insecure: there is no authentication, no encryption, and the commands -themselves are insecure too.

In -the absence of a simple tool to send and receive from bidirectional pipes, the -\fBecho\fP command can be used to send commands, but not receive replies from the -command prompt. -.sp -Assuming mpv was started with: -.INDENT 0.0 -.INDENT 3.5 -.sp -.nf -.ft C -mpv file.mkv \-\-input\-ipc\-server=\e\e.\epipe\empvsocket -.ft P -.fi -.UNINDENT -.UNINDENT -.sp -You can send commands from a command prompt: -.INDENT 0.0 -.INDENT 3.5 -.sp -.nf -.ft C -echo show\-text ${playback\-time} >\e\e.\epipe\empvsocket -.ft P -.fi -.UNINDENT -.UNINDENT -.sp -To be able to simultaneously read and write from the IPC pipe, like on Linux, -it\(aqs necessary to write an external program that uses overlapped file I/O (or -some wrapper like .NET\(aqs NamedPipeClientStream.) -.sp -You can open the pipe in PuTTY as "serial" device. This is not very -comfortable, but gives a way to test interactively without having to write code. -.SS Protocol -.sp -The protocol uses UTF\-8\-only JSON as defined by RFC\-8259. Unlike standard JSON, -"u" escape sequences are not allowed to construct surrogate pairs. To avoid -getting conflicts, encode all text characters including and above codepoint -U+0020 as UTF\-8. mpv might output broken UTF\-8 in corner cases (see "UTF\-8" -section below). -.sp -Clients can execute commands on the player by sending JSON messages of the -following form: -.INDENT 0.0 -.INDENT 3.5 -.sp -.nf -.ft C -{ "command": ["command_name", "param1", "param2", ...] } -.ft P -.fi -.UNINDENT -.UNINDENT -.sp -where \fBcommand_name\fP is the name of the command to be executed, followed by a -list of parameters. Parameters must be formatted as native JSON values -(integers, strings, booleans, ...). Every message \fBmust\fP be terminated with -\fB\en\fP\&. Additionally, \fB\en\fP must not appear anywhere inside the message. In -practice this means that messages should be minified before being sent to mpv. -.sp -mpv will then send back a reply indicating whether the command was run -correctly, and an additional field holding the command\-specific return data (it -can also be null). -.INDENT 0.0 -.INDENT 3.5 -.sp -.nf -.ft C -{ "error": "success", "data": null } -.ft P -.fi -.UNINDENT -.UNINDENT -.sp -mpv will also send events to clients with JSON messages of the following form: -.INDENT 0.0 -.INDENT 3.5 -.sp -.nf -.ft C -{ "event": "event_name" } -.ft P -.fi -.UNINDENT -.UNINDENT -.sp -where \fBevent_name\fP is the name of the event. Additional event\-specific fields -can also be present. See \fI\%List of events\fP for a list of all supported events. -.sp -Because events can occur at any time, it may be difficult at times to determine -which response goes with which command. Commands may optionally include a -\fBrequest_id\fP which, if provided in the command request, will be copied -verbatim into the response. mpv does not interpret the \fBrequest_id\fP in any -way; it is solely for the use of the requester. The only requirement is that -the \fBrequest_id\fP field must be an integer (a number without fractional parts -in the range \fB\-2^63..2^63\-1\fP). Using other types is deprecated and will -currently show a warning. In the future, this will raise an error. -.sp -For example, this request: -.INDENT 0.0 -.INDENT 3.5 -.sp -.nf -.ft C -{ "command": ["get_property", "time\-pos"], "request_id": 100 } -.ft P -.fi -.UNINDENT -.UNINDENT -.sp -Would generate this response: -.INDENT 0.0 -.INDENT 3.5 -.sp -.nf -.ft C -{ "error": "success", "data": 1.468135, "request_id": 100 } -.ft P -.fi -.UNINDENT -.UNINDENT -.sp -If you don\(aqt specify a \fBrequest_id\fP, command replies will set it to 0. -.sp -All commands, replies, and events are separated from each other with a line -break character (\fB\en\fP). -.sp -If the first character (after skipping whitespace) is not \fB{\fP, the command -will be interpreted as non\-JSON text command, as they are used in input.conf -(or \fBmpv_command_string()\fP in the client API). Additionally, lines starting -with \fB#\fP and empty lines are ignored. -.sp -Currently, embedded 0 bytes terminate the current line, but you should not -rely on this. -.SS Data flow -.sp -Currently, the mpv\-side IPC implementation does not service the socket while a -command is executed and the reply is written. It is for example not possible -that other events, that happened during the execution of the command, are -written to the socket before the reply is written. -.sp -This might change in the future. The only guarantee is that replies to IPC -messages are sent in sequence. -.sp -Also, since socket I/O is inherently asynchronous, it is possible that you read -unrelated event messages from the socket, before you read the reply to the -previous command you sent. In this case, these events were queued by the mpv -side before it read and started processing your command message. -.sp -If the mpv\-side IPC implementation switches away from blocking writes and -blocking command execution, it may attempt to send events at any time. -.sp -You can also use asynchronous commands, which can return in any order, and -which do not block IPC protocol interaction at all while the command is -executed in the background. -.SS Asynchronous commands -.sp -Command can be run asynchronously. This behaves exactly as with normal command -execution, except that execution is not blocking. Other commands can be sent -while it\(aqs executing, and command completion can be arbitrarily reordered. -.sp -The \fBasync\fP field controls this. If present, it must be a boolean. If missing, -\fBfalse\fP is assumed. -.sp -For example, this initiates an asynchronous command: -.INDENT 0.0 -.INDENT 3.5 -.sp -.nf -.ft C -{ "command": ["screenshot"], "request_id": 123, "async": true } -.ft P -.fi -.UNINDENT -.UNINDENT -.sp -And this is the completion: -.INDENT 0.0 -.INDENT 3.5 -.sp -.nf -.ft C -{"request_id":123,"error":"success","data":null} -.ft P -.fi -.UNINDENT -.UNINDENT -.sp -By design, you will not get a confirmation that the command was started. If a -command is long running, sending the message will lead to any reply until much -later when the command finishes. -.sp -Some commands execute synchronously, but these will behave like asynchronous -commands that finished execution immediately. -.sp -Cancellation of asynchronous commands is available in the libmpv API, but has -not yet been implemented in the IPC protocol. -.SS Commands with named arguments -.sp -If the \fBcommand\fP field is a JSON object, named arguments are expected. This -is described in the C API \fBmpv_command_node()\fP documentation (the -\fBMPV_FORMAT_NODE_MAP\fP case). In some cases, this may make commands more -readable, while some obscure commands basically require using named arguments. -.sp -Currently, only "proper" commands (as listed by \fI\%List of Input Commands\fP) -support named arguments. -.SS Commands -.sp -In addition to the commands described in \fI\%List of Input Commands\fP, a few -extra commands can also be used as part of the protocol: -.INDENT 0.0 -.TP -.B \fBclient_name\fP -Return the name of the client as string.

If it is unset, fully -qualified path names must be used. -.TP -.B \fBDISPLAY\fP -Standard X11 display name to use. -.TP -.B FFmpeg/Libav: -This library accesses various environment variables. However, they are not -centrally documented, and documenting them is not our job. Therefore, this -list is incomplete. -.sp -Notable environment variables: -.INDENT 7.0 -.TP -.B \fBhttp_proxy\fP -URL to proxy for \fBhttp://\fP and \fBhttps://\fP URLs. -.TP -.B \fBno_proxy\fP -List of domain patterns for which no proxy should be used. -List entries are separated by \fB,\fP\&. Patterns can include \fB*\fP\&. -.UNINDENT -.TP -.B libdvdcss: -.INDENT 7.0 -.TP -.B \fBDVDCSS_CACHE\fP -Specify a directory in which to store title key values. This will -speed up descrambling of DVDs which are in the cache. The -\fBDVDCSS_CACHE\fP directory is created if it does not exist, and a -subdirectory is created named after the DVD\(aqs title or manufacturing -date. If \fBDVDCSS_CACHE\fP is not set or is empty, libdvdcss will use -the default value which is \fB${HOME}/.dvdcss/\fP under Unix and -the roaming application data directory (\fB%APPDATA%\fP) under -Windows. The special value "off" disables caching. -.TP -.B \fBDVDCSS_METHOD\fP -Sets the authentication and decryption method that libdvdcss will use -to read scrambled discs. Can be one of \fBtitle\fP, \fBkey\fP or \fBdisc\fP\&. -.INDENT 7.0 -.TP -.B key -is the default method. libdvdcss will use a set of calculated -player keys to try to get the disc key. This can fail if the drive -does not recognize any of the player keys. -.TP -.B disc -is a fallback method when key has failed. Instead of using player -keys, libdvdcss will crack the disc key using a brute force -algorithm. This process is CPU intensive and requires 64 MB of -memory to store temporary data. -.TP -.B title -is the fallback when all other methods have failed. It does not -rely on a key exchange with the DVD drive, but rather uses a crypto -attack to guess the title key. On rare cases this may fail because -there is not enough encrypted data on the disc to perform a -statistical attack, but on the other hand it is the only way to -decrypt a DVD stored on a hard disc, or a DVD with the wrong region -on an RPC2 drive. -.UNINDENT -.TP -.B \fBDVDCSS_RAW_DEVICE\fP -Specify the raw device to use. Exact usage will depend on your -operating system, the Linux utility to set up raw devices is raw(8) -for instance. Please note that on most operating systems, using a raw -device requires highly aligned buffers: Linux requires a 2048 bytes -alignment (which is the size of a DVD sector). -.TP -.B \fBDVDCSS_VERBOSE\fP -Sets the libdvdcss verbosity level. -.INDENT 7.0 -.TP -.B 0 -Outputs no messages at all. -.TP -.B 1 -Outputs error messages to stderr. -.TP -.B 2 -Outputs error messages and debug messages to stderr. -.UNINDENT -.TP -.B \fBDVDREAD_NOKEYS\fP -Skip retrieving all keys on startup. Currently disabled. -.TP -.B \fBHOME\fP -FIXME: Document this. -.UNINDENT -.UNINDENT -.SH EXIT CODES -.sp -Normally \fBmpv\fP returns 0 as exit code after finishing playback successfully. -If errors happen, the following exit codes can be returned: -.INDENT 0.0 -.INDENT 3.5 -.INDENT 0.0 -.TP -.B 1 -Error initializing mpv. This is also returned if unknown options are -passed to mpv. -.TP -.B 2 -The file passed to mpv couldn\(aqt be played. This is somewhat fuzzy: -currently, playback of a file is considered to be successful if -initialization was mostly successful, even if playback fails -immediately after initialization. -.TP -.B 3 -There were some files that could be played, and some files which -couldn\(aqt (using the definition of success from above). -.TP -.B 4 -Quit due to a signal, Ctrl+c in a VO window (by default), or from the -default quit key bindings in encoding mode. -.UNINDENT -.UNINDENT -.UNINDENT -.sp -Note that quitting the player manually will always lead to exit code 0, -overriding the exit code that would be returned normally. Also, the \fBquit\fP -input command can take an exit code: in this case, that exit code is returned. -.SH FILES -.sp -For Windows\-specifics, see \fI\%FILES ON WINDOWS\fP section. -.INDENT 0.0 -.TP -.B \fB/usr/local/etc/mpv/mpv.conf\fP -mpv system\-wide settings (depends on \fB\-\-prefix\fP passed to configure \- mpv -in default configuration will use \fB/usr/local/etc/mpv/\fP as config -directory, while most Linux distributions will set it to \fB/etc/mpv/\fP). -.TP -.B \fB~/.config/mpv\fP -The standard configuration directory. This can be overridden by environment -variables, in ascending order: -.INDENT 7.0 -.TP -.B 1 -If \fB$XDG_CONFIG_HOME\fP is set, then the derived configuration directory -will be \fB$XDG_CONFIG_HOME/mpv\fP\&. -.TP -.B 2 -If \fB$MPV_HOME\fP is set, then the derived configuration directory will be -\fB$MPV_HOME\fP\&. -.UNINDENT -.sp -If this directory, nor the original configuration directory (see below) do -not exist, mpv tries to create this directory automatically. -.TP -.B \fB~/.mpv/\fP -The original (pre 0.5.0) configuration directory. It will continue to be -read if present. -.sp -If both this directory and the standard configuration directory are -present, configuration will be read from both with the standard -configuration directory content taking precedence. However, you should -fully migrate to the standard directory and a warning will be shown in -this situation. -.TP -.B \fB~/.config/mpv/mpv.conf\fP -mpv user settings (see \fI\%CONFIGURATION FILES\fP section) -.TP -.B \fB~/.config/mpv/input.conf\fP -key bindings (see \fI\%INPUT.CONF\fP section) -.TP -.B \fB~/.config/mpv/fonts.conf\fP -Fontconfig fonts.conf that is customized for mpv. You should include system -fonts.conf in this file or mpv would not know about fonts that you already -have in the system. -.sp -Only available when libass is built with fontconfig. -.TP -.B \fB~/.config/mpv/subfont.ttf\fP -fallback subtitle font -.TP -.B \fB~/.config/mpv/fonts/\fP -Font files in this directory are used by mpv/libass for subtitles. Useful -if you do not want to install fonts to your system. Note that files in this -directory are loaded into memory before being used by mpv. If you have a -lot of fonts, consider using fonts.conf (see above) to include additional -fonts, which is more memory\-efficient. -.TP -.B \fB~/.config/mpv/scripts/\fP -All files in this directory are loaded as if they were passed to the -\fB\-\-script\fP option. They are loaded in alphabetical order. -.sp -The \fB\-\-load\-scripts=no\fP option disables loading these files. -.sp -See \fI\%Script location\fP for details. -.TP -.B \fB~/.config/mpv/watch_later/\fP -Contains temporary config files needed for resuming playback of files with -the watch later feature. See for example the \fBQ\fP key binding, or the -\fBquit\-watch\-later\fP input command. -.sp -Each file is a small config file which is loaded if the corresponding media -file is loaded. It contains the playback position and some (not necessarily -all) settings that were changed during playback. The filenames are hashed -from the full paths of the media files. It\(aqs in general not possible to -extract the media filename from this hash. However, you can set the -\fB\-\-write\-filename\-in\-watch\-later\-config\fP option, and the player will -add the media filename to the contents of the resume config file. -.TP -.B \fB~/.config/mpv/script\-opts/osc.conf\fP -This is loaded by the OSC script. See the \fI\%ON SCREEN CONTROLLER\fP docs -for details. -.sp -Other files in this directory are specific to the corresponding scripts -as well, and the mpv core doesn\(aqt touch them. -.UNINDENT -.SH FILES ON WINDOWS -.sp -On win32 (if compiled with MinGW, but not Cygwin), the default config file -locations are different. They are generally located under \fB%APPDATA%/mpv/\fP\&. -For example, the path to mpv.conf is \fB%APPDATA%/mpv/mpv.conf\fP, which maps to -a system and user\-specific path, for example -.INDENT 0.0 -.INDENT 3.5 -\fBC:\eusers\eUSERNAME\eAppData\eRoaming\empv\empv.conf\fP -.UNINDENT -.UNINDENT -.sp -You can find the exact path by running \fBecho %APPDATA%\empv\empv.conf\fP in cmd.exe. -.sp -Other config files (such as \fBinput.conf\fP) are in the same directory. See the -\fI\%FILES\fP section above. -.sp -The environment variable \fB$MPV_HOME\fP completely overrides these, like on -UNIX. -.sp -If a directory named \fBportable_config\fP next to the mpv.exe exists, all -config will be loaded from this directory only. Watch later config files are -written to this directory as well. (This exists on Windows only and is redundant -with \fB$MPV_HOME\fP\&. However, since Windows is very scripting unfriendly, a -wrapper script just setting \fB$MPV_HOME\fP, like you could do it on other -systems, won\(aqt work. \fBportable_config\fP is provided for convenience to get -around this restriction.) -.sp -Config files located in the same directory as \fBmpv.exe\fP are loaded with -lower priority. Some config files are loaded only once, which means that -e.g. of 2 \fBinput.conf\fP files located in two config directories, only the -one from the directory with higher priority will be loaded. -.sp -A third config directory with the lowest priority is the directory named \fBmpv\fP -in the same directory as \fBmpv.exe\fP\&. This used to be the directory with the -highest priority, but is now discouraged to use and might be removed in the -future. -.sp -Note that mpv likes to mix \fB/\fP and \fB\e\fP path separators for simplicity. -kernel32.dll accepts this, but cmd.exe does not. -.SH COPYRIGHT -GPLv2+ -.\" Generated by docutils manpage writer. -.
