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. .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 u Switch between applying no style overrides to SSA/ASS subtitles, and overriding them almost completely with the normal subtitle style. See \fB\-\-sub\-ass\-override\fP for more info. .TP .B V Toggle subtitle VSFilter aspect compatibility mode. See \fB\-\-sub\-ass\-vsfilter\-aspect\-compat\fP for more info. .TP .B r and R Move subtitles up/down. The \fBt\fP key does the same as \fBR\fP currently, but use is discouraged. .TP .B s Take a screenshot. .TP .B S Take a screenshot, without subtitles. (Whether this works depends on VO driver support.) .TP .B Ctrl s Take a screenshot, as the window shows it (with subtitles, OSD, and scaled video). .TP .B PGUP and PGDWN Seek to the beginning of the previous/next chapter. In most cases, "previous" will actually go to the beginning of the current chapter; see \fB\-\-chapter\-seek\-threshold\fP\&. .TP .B Shift+PGUP and Shift+PGDWN Seek backward or forward by 10 minutes. (This used to be mapped to PGUP/PGDWN without Shift.) .TP .B d Activate/deactivate deinterlacer. .TP .B A Cycle aspect ratio override. .TP .B Ctrl h Toggle hardware video decoding on/off. .TP .B Alt+LEFT, Alt+RIGHT, Alt+UP, Alt+DOWN Move the video rectangle (panning). .TP .B Alt + and Alt \- Combining \fBAlt\fP with the \fB+\fP or \fB\-\fP keys changes video zoom. .TP .B Alt+BACKSPACE Reset the pan/zoom settings. .TP .B F8 Show the playlist and the current position in it (useful only if a UI window is used, broken on the terminal). .TP .B F9 Show the list of audio and subtitle streams (useful only if a UI window is used, broken on the terminal). .TP .B i and I Show/toggle an overlay displaying statistics about the currently playing file such as codec, framerate, number of dropped frames and so on. See \fI\%STATS\fP for more information. .UNINDENT .sp (The following keys are valid only when using a video output that supports the corresponding adjustment.) .INDENT 0.0 .TP .B 1 and 2 Adjust contrast. .TP .B 3 and 4 Adjust brightness. .TP .B 5 and 6 Adjust gamma. .TP .B 7 and 8 Adjust saturation. .TP .B Alt+0 (and command+0 on OSX) Resize video window to half its original size. .TP .B Alt+1 (and command+1 on OSX) Resize video window to its original size. .TP .B Alt+2 (and command+2 on OSX) Resize video window to double its original size. .TP .B command + f (OSX only) Toggle fullscreen (see also \fB\-\-fs\fP). .UNINDENT .sp (The following keys are valid if you have a keyboard with multimedia keys.) .INDENT 0.0 .TP .B PAUSE Pause. .TP .B STOP Stop playing and quit. .TP .B PREVIOUS and NEXT Seek backward/forward 1 minute. .UNINDENT .sp If you miss some older key bindings, look at \fBetc/restore\-old\-bindings.conf\fP in the mpv git repository. .SS Mouse Control .INDENT 0.0 .TP .B button 3 and button 4 Seek backward/forward 1 minute. .TP .B button 5 and button 6 Decrease/increase volume. .UNINDENT .SH USAGE .sp Command line arguments starting with \fB\-\fP are interpreted as options, everything else as filenames or URLs. 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 Currently, the parser makes no difference whether an option starts with \fB\-\-\fP or a single \fB\-\fP\&. This might also change in the future, and \fB\-\-option value\fP might always interpret \fBvalue\fP as filename in order to reduce ambiguities. .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 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~~/\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.) There are the following paths as well: .TS center; |l|l|. _ T{ Name T} T{ Meaning T} _ T{ \fB~~home/\fP T} T{ same as \fB~~/\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 OSX bundle resource path (OSX only) T} _ T{ \fB~~desktop/\fP T} T{ the path to the desktop (win32, OSX) 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, you can set a \fB,\fP\-separated list of filters with \fB\-\-vf\fP, but the option also allows you to append filters with \fB\-\-vf\-append\fP\&. .sp Options for filenames do not use \fB,\fP as separator, but \fB:\fP (Unix) or \fB;\fP (Windows). .TS center; |l|l|. _ T{ Suffix T} T{ Meaning T} _ T{ \-add T} T{ Append 1 or more items (may become alias for \-append) T} _ T{ \-append T} T{ Append single item (avoids need for escaping) T} _ T{ \-clr T} T{ Clear the option T} _ T{ \-del T} T{ Delete an existing item by integer index T} _ T{ \-pre T} T{ Prepend 1 or more items T} _ T{ \-set T} T{ Set a list of items T} _ T{ \-toggle T} T{ Append an item, or remove if if it already exists T} _ .TE .sp Although some operations allow specifying multiple \fB,\fP\-separated items, using this is strongly discouraged and deprecated, except for \fB\-set\fP\&. .sp Without suffix, the action taken is normally \fB\-set\fP\&. .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 Some options only support a subset of the above. .sp Options of this type can be changed at runtime using the \fBchange\-list\fP command, which takes the suffix as separate operation parameter. .SS Playing DVDs .sp DVDs can be played with the \fBdvd://[title]\fP syntax. The optional title specifier is a number which selects between separate video streams on the DVD. If no title is given (\fBdvd://\fP) then the longest title is selected automatically by the library. This is usually what you want. mpv does not support DVD menus. .sp DVDs which have been copied on to a hard drive or other mounted filesystem (by e.g. the \fBdvdbackup\fP tool) are accommodated by specifying the path to the local copy: \fB\-\-dvd\-device=PATH\fP\&. Alternatively, running \fBmpv PATH\fP should auto\-detect a DVD directory tree and play the longest title. .sp \fBNOTE:\fP .INDENT 0.0 .INDENT 3.5 DVD subtitles .sp DVDs use image\-based subtitles. Image subtitles are implemented as a bitmap video stream which can be superimposed over the main movie. mpv\(aqs subtitle styling and positioning options and keyboard shortcuts generally do not work with image\-based subtitles. Exceptions include options like \fB\-\-stretch\-dvd\-subs\fP and \fB\-\-stretch\-image\-subs\-to\-screen\fP\&. .UNINDENT .UNINDENT .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\&. Even suboptions can be specified in this way. .INDENT 0.0 .INDENT 3.5 .IP "Example configuration file" .INDENT 0.0 .INDENT 3.5 .sp .nf .ft C # Use GPU\-accelerated video output by default. vo=gpu # Use quotes for text that can contain spaces: status\-msg="Time: ${time\-pos}" .ft P .fi .UNINDENT .UNINDENT .UNINDENT .UNINDENT .SS Escaping spaces and special characters .sp This is done like with command line options. 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. Here is a small guide: .TS center; |l|l|. _ T{ Option T} T{ Configuration file entry T} _ T{ \fB\-\-flag\fP T} T{ \fBflag\fP T} _ T{ \fB\-opt val\fP T} T{ \fBopt=val\fP T} _ T{ \fB\-\-opt=val\fP T} T{ \fBopt=val\fP T} _ T{ \fB\-opt "has spaces"\fP T} T{ \fBopt="has spaces"\fP T} _ .TE .SS File\-specific Configuration Files .sp You can also write file\-specific configuration files. 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=\fP (replace \fB\fP with the profile name). You can apply profiles on start with the \fB\-\-profile=\fP option, or at runtime with the \fBapply\-profile \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 Auto profiles .sp Some profiles are loaded automatically. The following example demonstrates this: .INDENT 0.0 .INDENT 3.5 .IP "Auto profile loading" .INDENT 0.0 .INDENT 3.5 .sp .nf .ft C [protocol.dvd] profile\-desc="profile for dvd:// streams" alang=en [extension.flv] profile\-desc="profile for .flv files" vf=flip .ft P .fi .UNINDENT .UNINDENT .UNINDENT .UNINDENT .sp The profile name follows the schema \fBtype.name\fP, where type can be \fBprotocol\fP for the input/output protocol in use (see \fB\-\-list\-protocols\fP), and \fBextension\fP for the extension of the path of the currently played file (\fInot\fP the file format). .sp This feature is very limited, and there are no other auto profiles. .SH TAKING SCREENSHOTS .sp Screenshots of the currently played file can be taken using the \(aqscreenshot\(aq input mode command, which is by default bound to the \fBs\fP key. Files named \fBmpv\-shotNNNN.jpg\fP will be saved in the working directory, using the first available number \- no files will be overwritten. In pseudo\-GUI mode, the screenshot will be saved somewhere else. See \fI\%PSEUDO GUI MODE\fP\&. .sp A screenshot will usually contain the unscaled video contents at the end of the video filter chain and subtitles. By default, \fBS\fP takes screenshots without subtitles, while \fBs\fP includes subtitles. .sp Unlike with MPlayer, the \fBscreenshot\fP video filter is not required. This filter was never required in mpv, and has been removed. .SH TERMINAL STATUS LINE .sp During playback, mpv shows the playback status on the terminal. It looks like something like this: .INDENT 0.0 .INDENT 3.5 \fBAV: 00:03:12 / 00:24:25 (13%) A\-V: \-0.000\fP .UNINDENT .UNINDENT .sp The status line can be overridden with the \fB\-\-term\-status\-msg\fP option. .sp The following is a list of things that can show up in the status line. Input properties, that can be used to get the same information manually, are also listed. .INDENT 0.0 .IP \(bu 2 \fBAV:\fP or \fBV:\fP (video only) or \fBA:\fP (audio only) .IP \(bu 2 The current time position in \fBHH:MM:SS\fP format (\fBplayback\-time\fP property) .IP \(bu 2 The total file duration (absent if unknown) (\fBlength\fP property) .IP \(bu 2 Playback speed, e.g. \(ga\(ga x2.0\(ga\(ga. Only visible if the speed is not normal. This is the user\-requested speed, and not the actual speed (usually they should be the same, unless playback is too slow). (\fBspeed\fP property.) .IP \(bu 2 Playback percentage, e.g. \fB(13%)\fP\&. How much of the file has been played. Normally calculated out of playback position and duration, but can fallback to other methods (like byte position) if these are not available. (\fBpercent\-pos\fP property.) .IP \(bu 2 The audio/video sync as \fBA\-V: 0.000\fP\&. This is the difference between audio and video time. Normally it should be 0 or close to 0. If it\(aqs growing, it might indicate a playback problem. (\fBavsync\fP property.) .IP \(bu 2 Total A/V sync change, e.g. \fBct: \-0.417\fP\&. Normally invisible. Can show up if there is audio "missing", or not enough frames can be dropped. Usually this will indicate a problem. (\fBtotal\-avsync\-change\fP property.) .IP \(bu 2 Encoding state in \fB{...}\fP, only shown in encoding mode. .IP \(bu 2 Display sync state. If display sync is active (\fBdisplay\-sync\-active\fP property), this shows \fBDS: 2.500/13\fP, where the first number is average number of vsyncs per video frame (e.g. 2.5 when playing 24Hz videos on 60Hz screens), which might jitter if the ratio doesn\(aqt round off, or there are mistimed frames (\fBvsync\-ratio\fP), and the second number of estimated number of vsyncs which took too long (\fBvo\-delayed\-frame\-count\fP property). The latter is a heuristic, as it\(aqs generally not possible to determine this with certainty. .IP \(bu 2 Dropped frames, e.g. \fBDropped: 4\fP\&. Shows up only if the count is not 0. Can grow if the video framerate is higher than that of the display, or if video rendering is too slow. May also be incremented on "hiccups" and when the video frame couldn\(aqt be displayed on time. (\fBvo\-drop\-frame\-count\fP property.) If the decoder drops frames, the number of decoder\-dropped frames is appended to the display as well, e.g.: \fBDropped: 4/34\fP\&. This happens only if decoder frame dropping is enabled with the \fB\-\-framedrop\fP options. (\fBdrop\-frame\-count\fP property.) .IP \(bu 2 Cache state, e.g. \fBCache: 2s/134KB\fP\&. Visible if the stream cache is enabled. The first value shows the amount of video buffered in the demuxer in seconds, the second value shows the estimated size of the buffered amount in kilobytes. (\fBdemuxer\-cache\-duration\fP and \fBdemuxer\-cache\-state\fP properties.) .UNINDENT .SH LOW LATENCY PLAYBACK .sp mpv is optimized for normal video playback, meaning it actually tries to buffer as much data as it seems to make sense. This will increase latency. Reducing latency is possible only by specifically disabling features which increase latency. .sp The builtin \fBlow\-latency\fP profile tries to apply some of the options which can reduce latency. You can use \fB\-\-profile=low\-latency\fP to apply all of them. You can list the contents with \fB\-\-show\-profile=low\-latency\fP (some of the options are quite obscure, and may change every mpv release). .sp Be aware that some of the options can reduce playback quality. .sp Most latency is actually caused by inconvenient timing behavior. You can disable this with \fB\-\-untimed\fP, but it will likely break, unless the stream has no audio, and the input feeds data to the player at a constant rate. .sp Another common problem is with MJPEG streams. These do not signal the correct framerate. Using \fB\-\-untimed\fP or \fB\-\-no\-correct\-pts \-\-fps=60\fP might help. .sp For livestreams, data can build up due to pausing the stream, due to slightly lower playback rate, or "buffering" pauses. If the demuxer cache is enabled, these can be skipped manually. The experimental \fBdrop\-buffers\fP command can be used to discard any buffered data, though it\(aqs very disruptive. .sp In some cases, manually tuning TCP buffer sizes and such can help to reduce latency. .sp Additional options that can be tried: .INDENT 0.0 .IP \(bu 2 \fB\-\-opengl\-glfinish=yes\fP, can reduce buffering in the graphics driver .IP \(bu 2 \fB\-\-opengl\-swapinterval=0\fP, same .IP \(bu 2 \fB\-\-vo=xv\fP, same .IP \(bu 2 without audio \fB\-\-framedrop=no \-\-speed=1.01\fP may help for live sources (results can be mixed) .UNINDENT .SH PROTOCOLS .sp \fBhttp://...\fP, \fBhttps://\fP, ... .INDENT 0.0 .INDENT 3.5 Many network protocols are supported, but the protocol prefix must always be specified. mpv will never attempt to guess whether a filename is actually a network address. A protocol prefix is always required. .sp Note that not all prefixes are documented here. Undocumented prefixes are either aliases to documented protocols, or are just redirections to protocols implemented and documented in FFmpeg. .sp \fBdata:\fP is supported in FFmpeg (not in Libav), but needs to be in the format \fBdata://\fP\&. This is done to avoid ambiguity with filenames. You can also prefix it with \fBlavf://\fP or \fBffmpeg://\fP\&. .UNINDENT .UNINDENT .sp \fBytdl://...\fP .INDENT 0.0 .INDENT 3.5 By default, the youtube\-dl hook script (enabled by default for mpv CLI) only looks at http URLs. Prefixing an URL with \fBytdl://\fP forces it to be always processed by the script. This can also be used to invoke special youtube\-dl functionality like playing a video by ID or invoking search. .sp Keep in mind that you can\(aqt pass youtube\-dl command line options by this, and you have to use \fB\-\-ytdl\-raw\-options\fP instead. .UNINDENT .UNINDENT .sp \fB\-\fP .INDENT 0.0 .INDENT 3.5 Play data from stdin. .UNINDENT .UNINDENT .sp \fBsmb://PATH\fP .INDENT 0.0 .INDENT 3.5 Play a path from Samba share. .UNINDENT .UNINDENT .sp \fBbd://[title][/device]\fP \fB\-\-bluray\-device=PATH\fP .INDENT 0.0 .INDENT 3.5 Play a Blu\-ray disc. Since libbluray 1.0.1, you can read from ISO files by passing them to \fB\-\-bluray\-device\fP\&. .sp \fBtitle\fP can be: \fBlongest\fP or \fBfirst\fP (selects the default playlist); \fBmpls/\fP (selects .mpls playlist); \fB\fP (select playlist with the same index). mpv will list the available playlists on loading. .sp \fBbluray://\fP is an alias. .UNINDENT .UNINDENT .sp \fBdvd://[title|[starttitle]\-endtitle][/device]\fP \fB\-\-dvd\-device=PATH\fP .INDENT 0.0 .INDENT 3.5 Play a DVD. DVD menus are not supported.

This is what MPlayer and older mpv versions used for \fBdvd://\fP\&. Use is discouraged.

Basically, this passed the string after the \fB//\fP directly to libavformat. .UNINDENT .UNINDENT .sp \fBav://type:options\fP .INDENT 0.0 .INDENT 3.5 This is intended for using libavdevice inputs. \fBtype\fP is the libavdevice demuxer name, and \fBoptions\fP is the (pseudo\-)filename passed to the demuxer. .sp For example, \fBmpv av://lavfi:mandelbrot\fP makes use of the libavfilter wrapper included in libavdevice, and will use the \fBmandelbrot\fP source filter to generate input data. .sp \fBavdevice://\fP is an alias. .UNINDENT .UNINDENT .sp \fBfile://PATH\fP .INDENT 0.0 .INDENT 3.5 A local path as URL.

Note that \fBPATH\fP itself should start with a third \fB/\fP to make the path an absolute path. .UNINDENT .UNINDENT .sp \fBappending://PATH\fP .INDENT 0.0 .INDENT 3.5 Play a local file, but assume it\(aqs being appended to. This is useful for example for files that are currently being downloaded to disk. This will block playback, and stop playback only if no new data was appended after a timeout of about 2 seconds. .sp Using this is still a bit of a bad idea, because there is no way to detect if a file is actually being appended, or if it\(aqs still written. If you\(aqre trying to play the output of some program, consider using a pipe (\fBsomething | mpv \-\fP). If it really has to be a file on disk, use tail to make it wait forever, e.g. \fBtail \-f \-c +0 file.mkv | mpv \-\fP\&. .UNINDENT .UNINDENT .sp \fBfd://123\fP .INDENT 0.0 .INDENT 3.5 Read data from the given file descriptor (for example 123). This is similar to piping data to stdin via \fB\-\fP, but can use an arbitrary file descriptor. mpv may modify some file descriptor properties when the stream layer "opens" it. .UNINDENT .UNINDENT .sp \fBfdclose://123\fP .INDENT 0.0 .INDENT 3.5 Like \fBfd://\fP, but the file descriptor is closed after use. When using this you need to ensure that the same fd URL will only be used once. .UNINDENT .UNINDENT .sp \fBedl://[edl specification as in edl\-mpv.rst]\fP .INDENT 0.0 .INDENT 3.5 Stitch together parts of multiple files and play them. .UNINDENT .UNINDENT .sp \fBnull://\fP .INDENT 0.0 .INDENT 3.5 Simulate an empty file. If opened for writing, it will discard all data. The \fBnull\fP demuxer will specifically pass autoprobing if this protocol is used (while it\(aqs not automatically invoked for empty files). .UNINDENT .UNINDENT .sp \fBmemory://data\fP .INDENT 0.0 .INDENT 3.5 Use the \fBdata\fP part as source data. .UNINDENT .UNINDENT .sp \fBhex://data\fP .INDENT 0.0 .INDENT 3.5 Like \fBmemory://\fP, but the string is interpreted as hexdump. .UNINDENT .UNINDENT .SH PSEUDO GUI MODE .sp mpv has no official GUI, other than the OSC (\fI\%ON SCREEN CONTROLLER\fP), which is not a full GUI and is not meant to be. However, to compensate for the lack of expected GUI behavior, mpv will in some cases start with some settings changed to behave slightly more like a GUI mode. .sp Currently this happens only in the following cases: .INDENT 0.0 .IP \(bu 2 if started using the \fBmpv.desktop\fP file on Linux (e.g. started from menus or file associations provided by desktop environments) .IP \(bu 2 if started from explorer.exe on Windows (technically, if it was started on Windows, and all of the stdout/stderr/stdin handles are unset) .IP \(bu 2 started out of the bundle on OSX .IP \(bu 2 if you manually use \fB\-\-player\-operation\-mode=pseudo\-gui\fP on the command line .UNINDENT .sp This mode applies options from the builtin profile \fBbuiltin\-pseudo\-gui\fP, but only if these haven\(aqt been set in the user\(aqs config file or on the command line. Also, for compatibility with the old pseudo\-gui behavior, the options in the \fBpseudo\-gui\fP profile are applied unconditionally. In addition, the profile makes sure to enable the pseudo\-GUI mode, so that \fB\-\-profile=pseudo\-gui\fP works like in older mpv releases. The profiles are currently defined as follows: .INDENT 0.0 .INDENT 3.5 .sp .nf .ft C [builtin\-pseudo\-gui] terminal=no force\-window=yes idle=once screenshot\-directory=~~desktop/ [pseudo\-gui] player\-operation\-mode=pseudo\-gui .ft P .fi .UNINDENT .UNINDENT .sp \fBWARNING:\fP .INDENT 0.0 .INDENT 3.5 Currently, you can extend the \fBpseudo\-gui\fP profile in the config file the normal way. This is deprecated. In future mpv releases, the behavior might change, and not apply your additional settings, and/or use a different profile name. .UNINDENT .UNINDENT .SH OPTIONS .SS Track Selection .INDENT 0.0 .TP .B \fB\-\-alang=\fP Specify a priority list of audio languages to use.

See also \fB\-\-alang\fP\&. mpv normally prints available audio tracks on the terminal when starting playback of a file. .sp \fB\-\-audio\fP is an alias for \fB\-\-aid\fP\&. .sp \fB\-\-aid=no\fP or \fB\-\-audio=no\fP or \fB\-\-no\-audio\fP disables audio playback. (The latter variant does not work with the client API.) .TP .B \fB\-\-sid=\fP Display the subtitle stream specified by \fB\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.) .sp If video is disabled, mpv will try to download the audio only if media is streamed with youtube\-dl, because it saves bandwidth. This is done by setting the ytdl_format to "bestaudio/best" in the ytdl_hook.lua script. .TP .B \fB\-\-edition=\fP (Matroska files only) Specify the edition (set of chapters) to use, where 0 is the first. If set to \fBauto\fP (the default), mpv will choose the first edition declared as a default, or if there is no default, the first edition defined. .TP .B \fB\-\-track\-auto\-selection=\fP Enable the default track auto\-selection (default: yes). Enabling this will make the player select streams according to \fB\-\-aid\fP, \fB\-\-alang\fP, and others. If it is disabled, no tracks are selected. In addition, the player will not exit if no tracks are selected, and wait instead (this wait mode is similar to pausing, but the pause option is not set). .sp This is useful with \fB\-\-lavfi\-complex\fP: you can start playback in this mode, and then set select tracks at runtime by setting the filter graph. Note that if \fB\-\-lavfi\-complex\fP is set before playback is started, the referenced tracks are always selected. .UNINDENT .SS Playback Control .INDENT 0.0 .TP .B \fB\-\-start=\fP Seek to given time position. .sp The general format for times is \fB[+|\-][[hh:]mm:]ss[.ms]\fP\&. If the time is prefixed with \fB\-\fP, the time is considered relative from the end of the file (as signaled by the demuxer/the file). A \fB+\fP is usually ignored (but see below). .sp The following alternative time specifications are recognized: .sp \fBpp%\fP seeks to percent position pp (0\-100). .sp \fB#c\fP seeks to chapter number c. (Chapters start from 1.) .sp \fBnone\fP resets any previously set option (useful for libmpv). .sp If \fB\-\-rebase\-start\-time=no\fP is given, then prefixing times with \fB+\fP makes the time relative to the start of the file. A timestamp without prefix is considered an absolute time, i.e. should seek to a frame with a timestamp as the file contains it. As a bug, but also a hidden feature, putting 1 or more spaces before the \fB+\fP or \fB\-\fP always interprets the time as absolute, which can be used to seek to negative timestamps (useful for debugging at most). .INDENT 7.0 .INDENT 3.5 .IP "Examples" .INDENT 0.0 .TP .B \fB\-\-start=+56\fP, \fB\-\-start=00:56\fP Seeks to the start time + 56 seconds. .TP .B \fB\-\-start=\-56\fP, \fB\-\-start=\-00:56\fP Seeks to the end time \- 56 seconds. .TP .B \fB\-\-start=01:10:00\fP Seeks to 1 hour 10 min. .TP .B \fB\-\-start=50%\fP Seeks to the middle of the file. .TP .B \fB\-\-start=30 \-\-end=40\fP Seeks to 30 seconds, plays 10 seconds, and exits. .TP .B \fB\-\-start=\-3:20 \-\-length=10\fP Seeks to 3 minutes and 20 seconds before the end of the file, plays 10 seconds, and exits. .TP .B \fB\-\-start=\(aq#2\(aq \-\-end=\(aq#4\(aq\fP Plays chapters 2 and 3, and exits. .UNINDENT .UNINDENT .UNINDENT .TP .B \fB\-\-end=\fP Stop at given time.

See \fB\-\-start\fP for valid option values and examples. .TP .B \fB\-\-length=\fP Stop after a given time relative to the start time. See \fB\-\-start\fP for valid option values and examples. .sp If both \fB\-\-end\fP and \fB\-\-length\fP are provided, playback will stop when it reaches either of the two endpoints. .sp Obscurity note: this does not work correctly if \fB\-\-rebase\-start\-time=no\fP, and the specified time is not an "absolute" time, as defined in the \fB\-\-start\fP option description. .TP .B \fB\-\-rebase\-start\-time=\fP Whether to move the file start time to \fB00:00:00\fP (default: yes). This is less awkward for files which start at a random timestamp, such as transport streams. On the other hand, if there are timestamp resets, the resulting behavior can be rather weird. For this reason, and in case you are actually interested in the real timestamps, this behavior can be disabled with \fBno\fP\&. .TP .B \fB\-\-speed=<0.01\-100>\fP Slow down or speed up playback by the factor given as parameter. .sp If \fB\-\-audio\-pitch\-correction\fP (on by default) is used, playing with a speed higher than normal automatically inserts the \fBscaletempo\fP audio filter. .TP .B \fB\-\-pause\fP Start the player in paused state. .TP .B \fB\-\-shuffle\fP Play files in random order. .TP .B \fB\-\-playlist\-start=\fP Set which file on the internal playlist to start playback with. The index is an integer, with 0 meaning the first file. The value \fBauto\fP means that the selection of the entry to play is left to the playback resume mechanism (default). If an entry with the given index doesn\(aqt exist, the behavior is unspecified and might change in future mpv versions. The same applies if the playlist contains further playlists (don\(aqt expect any reasonable behavior). Passing a playlist file to mpv should work with this option, though. E.g. \fBmpv playlist.m3u \-\-playlist\-start=123\fP will work as expected, as long as \fBplaylist.m3u\fP does not link to further playlists. .sp The value \fBno\fP is a deprecated alias for \fBauto\fP\&. .TP .B \fB\-\-playlist=\fP Play files according to a playlist file (Supports some common formats. If no format is detected, it will be treated as list of files, separated by newline characters. Note that XML playlist formats are not supported.) .sp You can play playlists directly and without this option, however, this option disables any security mechanisms that might be in place. You may also need this option to load plaintext files as playlist. .sp \fBWARNING:\fP .INDENT 7.0 .INDENT 3.5 The way mpv uses playlist files via \fB\-\-playlist\fP is not safe against maliciously constructed files. Such files may trigger harmful actions. This has been the case for all mpv and MPlayer versions, but unfortunately this fact was not well documented earlier, and some people have even misguidedly recommended use of \fB\-\-playlist\fP with untrusted sources. Do NOT use \fB\-\-playlist\fP with random internet sources or files you do not trust! .sp Playlist can contain entries using other protocols, such as local files, or (most severely), special protocols like \fBavdevice://\fP, which are inherently unsafe. .UNINDENT .UNINDENT .TP .B \fB\-\-chapter\-merge\-threshold=\fP Threshold for merging almost consecutive ordered chapter parts in milliseconds (default: 100). Some Matroska files with ordered chapters have inaccurate chapter end timestamps, causing a small gap between the end of one chapter and the start of the next one when they should match. If the end of one playback part is less than the given threshold away from the start of the next one then keep playing video normally over the chapter change instead of doing a seek. .TP .B \fB\-\-chapter\-seek\-threshold=\fP Distance in seconds from the beginning of a chapter within which a backward chapter seek will go to the previous chapter (default: 5.0). Past this threshold, a backward chapter seek will go to the beginning of the current chapter instead. A negative value means always go back to the previous chapter. .TP .B \fB\-\-hr\-seek=\fP Select when to use precise seeks that are not limited to keyframes. Such seeks require decoding video from the previous keyframe up to the target position and so can take some time depending on decoding performance. For some video formats, precise seeks are disabled. This option selects the default choice to use for seeks; it is possible to explicitly override that default in the definition of key bindings and in input commands. .INDENT 7.0 .TP .B no Never use precise seeks. .TP .B absolute Use precise seeks if the seek is to an absolute position in the file, such as a chapter seek, but not for relative seeks like the default behavior of arrow keys (default). .TP .B yes Use precise seeks whenever possible. .TP .B always Same as \fByes\fP (for compatibility). .UNINDENT .TP .B \fB\-\-hr\-seek\-demuxer\-offset=\fP This option exists to work around failures to do precise seeks (as in \fB\-\-hr\-seek\fP) caused by bugs or limitations in the demuxers for some file formats. Some demuxers fail to seek to a keyframe before the given target position, going to a later position instead. The value of this option is subtracted from the time stamp given to the demuxer. Thus, if you set this option to 1.5 and try to do a precise seek to 60 seconds, the demuxer is told to seek to time 58.5, which hopefully reduces the chance that it erroneously goes to some time later than 60 seconds. The downside of setting this option is that precise seeks become slower, as video between the earlier demuxer position and the real target may be unnecessarily decoded. .TP .B \fB\-\-hr\-seek\-framedrop=\fP Allow the video decoder to drop frames during seek, if these frames are before the seek target. If this is enabled, precise seeking can be faster, but if you\(aqre using video filters which modify timestamps or add new frames, it can lead to precise seeking skipping the target frame. This e.g. can break frame backstepping when deinterlacing is enabled. .sp Default: \fByes\fP .TP .B \fB\-\-index=\fP Controls how to seek in files. Note that if the index is missing from a file, it will be built on the fly by default, so you don\(aqt need to change this. But it might help with some broken files. .INDENT 7.0 .TP .B default use an index if the file has one, or build it if missing .TP .B recreate don\(aqt read or use the file\(aqs index .UNINDENT .sp \fBNOTE:\fP .INDENT 7.0 .INDENT 3.5 This option only works if the underlying media supports seeking (i.e. not with stdin, pipe, etc). .UNINDENT .UNINDENT .TP .B \fB\-\-load\-unsafe\-playlists\fP Load URLs from playlists which are considered unsafe (default: no). This includes special protocols and anything that doesn\(aqt refer to normal files. Local files and HTTP links on the other hand are always considered safe. .sp In addition, if a playlist is loaded while this is set, the added playlist entries are not marked as originating from network or potentially unsafe location. (Instead, the behavior is as if the playlist entries were provided directly to mpv command line or \fBloadfile\fP command.) .sp Note that \fB\-\-playlist\fP always loads all entries, so you use that instead if you really have the need for this functionality. .TP .B \fB\-\-access\-references=\fP Follow any references in the file being opened (default: yes). Disabling this is helpful if the file is automatically scanned (e.g. thumbnail generation). If the thumbnail scanner for example encounters a playlist file, which contains network URLs, and the scanner should not open these, enabling this option will prevent it. This option also disables ordered chapters, mov reference files, opening of archives, and a number of other features. .sp On older FFmpeg versions, this will not work in some cases. Some FFmpeg demuxers might not respect this option. .sp This option does not prevent opening of paired subtitle files and such. Use \fB\-\-autoload\-files=no\fP to prevent this. .sp This option does not always work if you open non\-files (for example using \fBdvd://directory\fP would open a whole bunch of files in the given directory). Prefixing the filename with \fB\&./\fP if it doesn\(aqt start with a \fB/\fP will avoid this. .TP .B \fB\-\-loop\-playlist=\fP, \fB\-\-loop\-playlist\fP Loops playback \fBN\fP times. A value of \fB1\fP plays it one time (default), \fB2\fP two times, etc. \fBinf\fP means forever. \fBno\fP is the same as \fB1\fP and disables looping. If several files are specified on command line, the entire playlist is looped. \fB\-\-loop\-playlist\fP is the same as \fB\-\-loop\-playlist=inf\fP\&. .sp The \fBforce\fP mode is like \fBinf\fP, but does not skip playlist entries which have been marked as failing. This means the player might waste CPU time trying to loop a file that doesn\(aqt exist. But it might be useful for playing webradios under very bad network conditions. .TP .B \fB\-\-loop\-file=\fP, \fB\-\-loop=\fP Loop a single file N times. \fBinf\fP means forever, \fBno\fP means normal playback. For compatibility, \fB\-\-loop\-file\fP and \fB\-\-loop\-file=yes\fP are also accepted, and are the same as \fB\-\-loop\-file=inf\fP\&. .sp The difference to \fB\-\-loop\-playlist\fP is that this doesn\(aqt loop the playlist, just the file itself. If the playlist contains only a single file, the difference between the two option is that this option performs a seek on loop, instead of reloading the file. .sp \fB\-\-loop\fP is an alias for this option. .TP .B \fB\-\-ab\-loop\-a=
