== Configuration ==
  
System-wide configuration is located in {{ic|/etc/mpv/mpv.conf}}, whereas the user-local settings are stored in {{ic|~/.mpv/config}}. The complete list of options is located [https://github.com/mpv-player/mpv/blob/master/DOCS/man/en/options.rst here].
+
''mpv'''s configuration is read from the files {{ic|mpv.conf}} (settings), {{ic|input.conf}} (key bindings), and {{ic|lua-settings/osc.conf}} (on screen display). For a full list of options, see the {{man|1|mpv|url=https://mpv.io/manual/master/}} or the [https://github.com/mpv-player/mpv/tree/master/DOCS/man GitHub docs].
{{Tip|If you prefer a custom location for configurations, set the {{ic|MPV_HOME}} variable as you like in your shell configuration file. A predictable choice is {{ic|<nowiki>MPV_HOME=$XDG_CONFIG_HOME/mpv</nowiki>}}.}}
+
  
An example configuration:
+
If the [[environment variable]] {{ic|XDG_CONFIG_HOME}} is not set, user configuration files will be read from the {{ic|~/.config/mpv}} directory. System-wide configuration files are read from the {{ic|/etc/mpv}} directory.

+
Unlike ''mplayer'' and ''mplayer2'', ''mpv'' has both VA-API and VDPAU support built-in. To enable it, run ''mpv'' with the {{ic|1=--hwdec='method'}} option. You can find list of all available methods looking for {{ic|1=--hwdec=<api>}} in [[man page]] {{man|1|mpv|url=https://mpv.io/manual/master/}}. To make this persistent, add the line {{ic|1=hwdec=''method''}} to your configuration file.
af=scaletempo
+
  
# allow to seek in a file which is still downloading whilst watching it
+
When hardware decoding is used, the video output should generally be set to {{ic|opengl}} or {{ic|opengl-hq}} (or possibly {{ic|vdpau}} if using {{ic|1=hwdec=vdpau}}). In particular, {{ic|1=hwdec=vaapi}} should be used with {{ic|1=vo=opengl}} [https://github.com/mpv-player/mpv/blob/master/DOCS/man/vo.rst] if possible.
# from manpage:"this switch has no effect in the typical case" (usually done automatically by demuxers)

+
If hardware decoding cannot be used, ''mpv'' will automatically fall back to software decoding.
#softvol-max=600
+
  
# skip displaying some frames to maintain A/V sync on slow systems
+
By default, hardware decoding is enabled for codecs h264, vc1, wmv3, hevc, mpeg2video and vp9. It is however possible to specify codecs (e.g. {{ic|1=--hwdec-codecs=h264,mpeg2video}}) or allow all codecs ({{ic|1=hwdec-codecs=all}}) to use hardware decoding.

This comes with a GLSL debanding filter by default, which may lead to bad performance for some users, and can reduce the visual quality of grainy content. You can disable it easily though.

 +
 
 +
=== Automatically resuming from where you left off ===
 +
 
 +
The default key to quit ''mpv'', saving the video's current position and state, is {{ic|Shift+q}}. This key can be changed by adding the {{ic|quit_watch_later}} string in the key bindings configuration file.
 +
 
 +
To always automatically save the current playback position on quit, start ''mpv'' with a flag {{ic|--save-position-on-quit}}. To make option permanent, add line {{ic|save-position-on-quit}} to configuration file.
 +
 
 +
=== Volume is too low ===
 +
 
 +
Set {{ic|1=volume-max=''value''}} in your configuration file to a reasonable amount, such as {{ic|1=volume-max=600}}. Additionally (or alternatively), you can utilize [[Wikipedia:Dynamic range compression|dynamic range compression]] with {{ic|1=af=drc}}.
 +
 
 +
=== Quickly cycle between multiple aspect ratio ===
 +
 
 +
You can cycle between aspect ratios using {{ic|Shift+a}} from version 0.8.0 onwards.
 +
 
 +
=== Drawing to a root window ===
 +
 
 +
Run ''mpv'' with {{ic|1=--wid=0}}. This tells ''mpv'' to draw onto a window with a window ID of 0.
 +
 
 +
=== Always show GUI ===
 +
 
 +
It may be useful to always show the GUI window, even for audio files, especially when ''mpv'' is not started from terminal. This can be done by using {{ic|--force-window}} option.
 +
 
 +
=== Restoring old OSC ===
 +
 
 +
Since version 0.21.0, mpv has replaced the on-screen controls by a bottombar. In case you want on-screen controls back, you can edit the mpv configuration [https://github.com/mpv-player/mpv/wiki/FAQ#i-want-the-old-osc-back as described here].
 +
 
 +
=== Use as a browser plugin ===
 +
 
 +
With the help of {{AUR|mozplugger}}, ''mpv'' can be used in a supported browser to play video. See [[Browser plugins#MozPlugger]] for configuration details. This coupled with a user script such as [http://isebaro.com/viewtube/?ln=en ViewTube], allows you to use ''mpv'' in place of a site's integrated video player.
 +
 
 +
It may be needed to specify a valid user agent for HTTP streaming, e.g. {{ic|1=user-agent="Mozilla/5.0 (X11; Linux x86_64; rv:49.0) Gecko/20100101 Firefox/49.0"}}.
 +
 
 +
[[Browser plugins#Video players workarounds]] page shows other easy ways to watch videos.
 +
 
 +
=== Improving mpv as a music player with Lua scripts ===
 +
 
 +
The development of mpv's Lua scripts are documented in [https://github.com/mpv-player/mpv/blob/master/DOCS/man/lua.rst DOCS/man/lua.rst]
 +
and examples are shown in [https://github.com/mpv-player/mpv/tree/master/TOOLS/lua TOOLS/lua]
 +
of the [https://github.com/mpv-player/mpv mpv repository].
 +
[https://web.archive.org/web/20160320001546/http://bamos.github.io/2014/07/05/mpv-lua-scripting/ This blog post] introduces the
 +
[https://github.com/bamos/dotfiles/blob/master/.mpv/scripts/music.lua music.lua] script,
 +
which shows how Lua scripts can be used to improve mpv as a music player.
 +
 
 +
=== Twitch.tv streaming over mpv ===
 +
 
 +
If {{Pkg|youtube-dl}} is installed, mpv can directly open a Twitch livestream.
 +
 
 +
Alternatively, {{Pkg|livestreamer}} can be used to stream Twitch. See [[Livestreamer#Twitch]].
 +
 
 +
Another alternative based on Livestreamer is this Lua script: https://gist.github.com/ChrisK2/8701184fe3ea7701c9cc
 +
 
 +
=== youtube-dl and choosing formats ===
 +
 
 +
The default {{ic|--ytdl-format}} is {{ic|bestvideo+bestaudio/best}}. For youtube videos that have 4K resolutions available, this may mean that your device will struggle to decode 4K VP9 encoded video in software even if the attached monitor is much lower resolution.
 +
 
 +
Setting the right youtube-dl format selectors can fix this easily though. In the following configuration example, only videos with a vertical resolution of 1080 pixels or less will be considered.
 +
 
 +
ytdl-format=bestvideo[height<=?1080]+bestaudio/best
 +
 
 +
If you wish to avoid a certain codec altogether because you cannot hardware-decode it, you can add this to the format selector. For example, we can additionally choose to ignore VP9 as follows:
 +
 
 +
ytdl-format=bestvideo[height<=?1080][vcodec!=vp9]+bestaudio/best
 +
 
 +
=== youtube-dl audio with search ===
 +
 
 +
To find and play audio straight from your terminal with {{ic|mm "''search terms''"}} put the following function in your {{ic|.bashrc}}:
 +
 
 +
function mm() {
 +
    mpv --no-video --ytdl-format=bestaudio ytdl://ytsearch10:"$@"
 +
}
 +
 
 +
=== Use mpv with a compositor ===
 +
 
 +
If you're using a compositor (e.g. in KDE Plasma 5) and find that composition is disabled (e.g. in Plasma this would make you unable to present windows or see window thumbnails in the default app switcher) when mpv is playing a video, try {{ic|1=x11-bypass-compositor=no}}
 +
 
 +
=== Creating a single screenshot ===
 +
An example of creating a single screenshot, by using a start time ({{ic|HH:MM:SS}}):
 +
 
 +
$ mpv --no-audio --vo=image --start=00:01:30 --frames=1 /path/to/video/file
 +
 
 +
Screenshots will be saved as 00000001.jpg in the current directory.
 +
 
 +
== Vapoursynth ==
 +
 
 +
Vapoursynth is an alternative to AviSynth that can be used on Linux and allows for Video manipulation via python scripts. Vapoursynths python scripts can be used as video filters for ''mpv''.
 +
 
 +
To use vapoursynth filters you have to install the {{Pkg|vapoursynth}} package and compile ''mpv'' with the {{ic|--enable-vapoursynth}} build flag.
 +
 
 +
=== Debanding (flash3kyuu) ===
 +
 
 +
{{Note|Mpv already include a debanding shader which is enabled by default with the [[Mpv#High_quality_video_output|opengl-hq profile]]. Refer to the manual for more information on how to tune it.}}
 +
 
 +
To use the {{ic|f3k_db}} debanding filter install {{Pkg|vapoursynth-plugin-f3kdb}} and write a python script that uses the ''vapoursynth'' extension.
  
See another example at https://github.com/mpv-player/mpv/blob/master/etc/example.conf.
+
The following sample script can be used to enable debanding in ''mpv''.
  
== Hardware Decoding ==
+
import vapoursynth as vs
 +
core = vs.get_core()
 +
 +
clip = video_in
 +
clip = core.std.Trim(clip, first=0, length=500000)
 +
clip = core.f3kdb.Deband(clip, grainy=0, grainc=0, output_depth=16)
 +
clip.set_output()
  
You can reduce the CPU usage (and extend mobile battery life) by enabling GPU hardware decoding for common video codecs. Unlike mplayer, and mplayer2, mpv has both [[Wikipedia:VDPAU|VDPAU]] and [[Wikipedia:VAAPI|VAAPI]] built-in! To enable hardware decoding, add --hwdec=<method> to the mpv command line, where <method> is one of "auto", "vdpau", "vaapi". To make this persistent, add the line hwdec=<method> to the config file. With hardwarde decoding --hwdec=[vdpau|vaapi], the video output must be specified as --vo=opengl (preferred) or --vo=[vdpau|vaapi]. While --vo=opengl should generally be of better quality,--vo=vdpau may give better frame timings, and --vo=vaapi may use less power. If hardware decoding can't be used, mpv will automatically fallback to software decoding.
+
Finally specify the python script in the config file or use a command line argument when executing mpv.
 +
$ mpv --vf=vapoursynth=f3k_db.py <video_file>
  
== Key bindings ==
+
== Troubleshooting ==
  
System key bindings are configured via {{ic|/etc/mpv/input.conf}}. Personal key bindings are stored in {{ic|~/.mpv/input.conf}}.
+
=== Fix jerky playback and tearing ===
Available keybinds and configuration are explained in the [https://github.com/mpv-player/mpv/blob/master/DOCS/man/en/mpv.rst manual pages].
+
  
=== Automatic resuming from where you left off ===
+
mpv defaults to using the opengl video output device setting on hardware that supports it. In cases such as trying to play video back on a 4K display using a Intel HD4XXX series card or similar, you will find video playback unreliable, jerky to the point of stopping entirely at times and with major tearing when using any opengl output setting. If you experience any of these issues, using the xv (XVideo) video output device may help.
  
The default key to quit saving the video advance state is {{ic|Q}}. This behaviour is controlled by the {{ic|quit_watch_later}} string in the key bindings configuration file.
+
{{hc|1=~/.config/mpv/mpv.conf|2=vo=xv}}
  
=== Quick aspect ratio change ===
+
It is possible to increase decoding performance (especially on lower hardware), but this may affect the video quality. See the [[Mpv#Configuration|configuration section]] for information about the available options.
  
Append to your {{ic|input.conf}}:
+
The following options can be considered to increase video performance:
{{bc|
+
{{hc|~/.config/mpv/mpv.conf|2=
F1 set aspect 1.3333
+
vd-lavc-fast
F2 set aspect 1.6
+
vd-lavc-skiploopfilter=<skipvalue>
F3 set aspect 1.7777
+
vd-lavc-skipframe=<skipvalue>
F4 set aspect 1.85
+
vd-lavc-framedrop=<skipvalue>
F5 set aspect 0
+
vd-lavc-threads=<threads>
 
}}
 
}}
Now you are able to change the aspect ratio with {{ic|F1}} to {{ic|F5}}.

mpv is a media player based on MPlayer and MPlayer2. It supports a wide variety of video file formats, audio and video codecs, and subtitle types. A comprehensive (although admittedly incomplete) list of differences between mpv and the aforementioned players can be found here.

Installation

Install the mpv package from the official repositories or mpv-gitAUR from the Arch User Repository.

Front ends

mpv provides an elegant User Interface called OSC which appears when moving the mouse. To ease casual users, other graphical interfaces exist:

  • Baka MPlayer — Free and open source, cross-platform, libmpv based multimedia player (Qt 5).
http://bakamplayer.u8sand.net/ || baka-mplayer, baka-mplayer-gitAUR
  • bomi — Powerful and easy to use multimedia player (Qt 5).
https://bomi-player.github.io/ || bomiAUR, bomi-gitAUR
  • GNOME MPV — A simple frontend for mpv (GTK+ 3).
http://gnome-mpv.github.io/ || gnome-mpvAUR, gnome-mpv-gitAUR
https://github.com/cmdrkotori/mpc-qt || mpc-qt-gitAUR
  • SMPlayer — Qt multimedia player with extra features (CSS themes, YouTube integration, etc.) (Qt 5).
http://smplayer.sourceforge.net/ || smplayer
  • xt7-player-mpv — Qt/Gambas GUI to mpv with a rich set of configurable options including filters and drivers, ladspa plugins support as well as library/playlist managment, YouTube, online radios, podcasts, DVB-T and more.
https://github.com/kokoko3k/xt7-player-mpv || xt7-player-mpv-gitAUR
Note: CMPlayer/bomi packages provide mpv internally.

Configuration

mpv's configuration is read from the files mpv.conf (settings), input.conf (key bindings), and lua-settings/osc.conf (on screen display). For a full list of options, see the mpv(1) or the GitHub docs.

If the environment variable XDG_CONFIG_HOME is not set, user configuration files will be read from the ~/.config/mpv directory. System-wide configuration files are read from the /etc/mpv directory.

An example input.conf file

Copying the following into ~/.config/mpv/input.conf will add a number of useful keybindings to mpv such as rotating video 90 degrees, zooming and panning.

Alt+RIGHT add video-rotate 90
Alt+LEFT add video-rotate -90
Alt+- add video-zoom -0.25
Alt+= add video-zoom 0.25
Alt+j add video-pan-x -0.05
Alt+l add video-pan-x 0.05
Alt+i add video-pan-y 0.05
Alt+k add video-pan-y -0.05

mpv and PulseAudio since 0.18.1

This entry only applies if you are using pulseaudio for mpv (-ao=pulse or ao=pulse in mpv.conf).

Add the following to your ~/.config/mpv/input.conf to make volume changes work again from PulseAudio to mpv and vice versa:

/ add ao-volume -2
SHIFT+* add ao-volume 2

Change the above to whatever volume keys you use. The above is the default of MPV only handles by "softvol" and with those lines handled by PulseAudio.

Tips and Tricks

Hardware Decoding

See Hardware video acceleration.

Unlike mplayer and mplayer2, mpv has both VA-API and VDPAU support built-in. To enable it, run mpv with the --hwdec='method' option. You can find list of all available methods looking for --hwdec=<api> in man page mpv(1). To make this persistent, add the line hwdec=method to your configuration file.

When hardware decoding is used, the video output should generally be set to opengl or opengl-hq (or possibly vdpau if using hwdec=vdpau). In particular, hwdec=vaapi should be used with vo=opengl [1] if possible.

If hardware decoding cannot be used, mpv will automatically fall back to software decoding.

By default, hardware decoding is enabled for codecs h264, vc1, wmv3, hevc, mpeg2video and vp9. It is however possible to specify codecs (e.g. --hwdec-codecs=h264,mpeg2video) or allow all codecs (hwdec-codecs=all) to use hardware decoding.

High quality video output

The opengl-hq profile is a high quality preset which use the OpenGL video driver and enables various options selected by the mpv developers. To make use of it, specify it in your configuration file.

~/.config/mpv/mpv.conf
profile=opengl-hq

This comes with a GLSL debanding filter by default, which may lead to bad performance for some users, and can reduce the visual quality of grainy content. You can disable it easily though.

~/.config/mpv/mpv.conf
profile=opengl-hq
deband=no

Automatically resuming from where you left off

The default key to quit mpv, saving the video's current position and state, is Shift+q. This key can be changed by adding the quit_watch_later string in the key bindings configuration file.

To always automatically save the current playback position on quit, start mpv with a flag --save-position-on-quit. To make option permanent, add line save-position-on-quit to configuration file.

Volume is too low

Set volume-max=value in your configuration file to a reasonable amount, such as volume-max=600. Additionally (or alternatively), you can utilize dynamic range compression with af=drc.

Quickly cycle between multiple aspect ratio

You can cycle between aspect ratios using Shift+a from version 0.8.0 onwards.

Drawing to a root window

Run mpv with --wid=0. This tells mpv to draw onto a window with a window ID of 0.

Always show GUI

It may be useful to always show the GUI window, even for audio files, especially when mpv is not started from terminal. This can be done by using --force-window option.

Restoring old OSC

Since version 0.21.0, mpv has replaced the on-screen controls by a bottombar. In case you want on-screen controls back, you can edit the mpv configuration as described here.

Use as a browser plugin

With the help of mozpluggerAUR, mpv can be used in a supported browser to play video. See Browser plugins#MozPlugger for configuration details. This coupled with a user script such as ViewTube, allows you to use mpv in place of a site's integrated video player.

It may be needed to specify a valid user agent for HTTP streaming, e.g. user-agent="Mozilla/5.0 (X11; Linux x86_64; rv:49.0) Gecko/20100101 Firefox/49.0".

Improving mpv as a music player with Lua scripts

The development of mpv's Lua scripts are documented in DOCS/man/lua.rst and examples are shown in TOOLS/lua of the mpv repository. This blog post introduces the music.lua script, which shows how Lua scripts can be used to improve mpv as a music player.

Twitch.tv streaming over mpv

If youtube-dl is installed, mpv can directly open a Twitch livestream.

Alternatively, livestreamer can be used to stream Twitch. See Livestreamer#Twitch.

youtube-dl and choosing formats

The default --ytdl-format is bestvideo+bestaudio/best. For youtube videos that have 4K resolutions available, this may mean that your device will struggle to decode 4K VP9 encoded video in software even if the attached monitor is much lower resolution.

Setting the right youtube-dl format selectors can fix this easily though. In the following configuration example, only videos with a vertical resolution of 1080 pixels or less will be considered.

ytdl-format=bestvideo[height<=?1080]+bestaudio/best

If you wish to avoid a certain codec altogether because you cannot hardware-decode it, you can add this to the format selector. For example, we can additionally choose to ignore VP9 as follows:

ytdl-format=bestvideo[height<=?1080][vcodec!=vp9]+bestaudio/best

youtube-dl audio with search

To find and play audio straight from your terminal with mm "search terms" put the following function in your .bashrc:

function mm() {
    mpv --no-video --ytdl-format=bestaudio ytdl://ytsearch10:"$@"
}

Use mpv with a compositor

If you're using a compositor (e.g. in KDE Plasma 5) and find that composition is disabled (e.g. in Plasma this would make you unable to present windows or see window thumbnails in the default app switcher) when mpv is playing a video, try x11-bypass-compositor=no

Creating a single screenshot

An example of creating a single screenshot, by using a start time (HH:MM:SS):

$ mpv --no-audio --vo=image --start=00:01:30 --frames=1 /path/to/video/file

Screenshots will be saved as 00000001.jpg in the current directory.

Vapoursynth

Vapoursynth is an alternative to AviSynth that can be used on Linux and allows for Video manipulation via python scripts. Vapoursynths python scripts can be used as video filters for mpv.

To use vapoursynth filters you have to install the vapoursynth package and compile mpv with the --enable-vapoursynth build flag.

Debanding (flash3kyuu)

Note: Mpv already include a debanding shader which is enabled by default with the opengl-hq profile. Refer to the manual for more information on how to tune it.

To use the f3k_db debanding filter install vapoursynth-plugin-f3kdb and write a python script that uses the vapoursynth extension.

The following sample script can be used to enable debanding in mpv.

import vapoursynth as vs
core = vs.get_core()

clip = video_in
clip = core.std.Trim(clip, first=0, length=500000)
clip = core.f3kdb.Deband(clip, grainy=0, grainc=0, output_depth=16)
clip.set_output()

Finally specify the python script in the config file or use a command line argument when executing mpv.

$ mpv --vf=vapoursynth=f3k_db.py <video_file>

Troubleshooting

Fix jerky playback and tearing

mpv defaults to using the opengl video output device setting on hardware that supports it. In cases such as trying to play video back on a 4K display using a Intel HD4XXX series card or similar, you will find video playback unreliable, jerky to the point of stopping entirely at times and with major tearing when using any opengl output setting. If you experience any of these issues, using the xv (XVideo) video output device may help.

~/.config/mpv/mpv.conf
vo=xv

It is possible to increase decoding performance (especially on lower hardware), but this may affect the video quality. See the configuration section for information about the available options.

The following options can be considered to increase video performance:

~/.config/mpv/mpv.conf
vd-lavc-fast
vd-lavc-skiploopfilter=<skipvalue>
vd-lavc-skipframe=<skipvalue>
vd-lavc-framedrop=<skipvalue>
vd-lavc-threads=<threads>
