Installation
Install the mpv package or mpv-gitAUR for the development version.
Front ends
mpv comes with a minimal GUI called On Screen Controller (OSC), that appears when moving the mouse. There are also other front ends available:
- Baka MPlayer — Free and open source, cross-platform, libmpv based multimedia player (Qt 5).
- GNOME MPV — A simple frontend for mpv (GTK+ 3).
- Media Player Classic Qute Theater — A clone of Media Player Classic reimplimented in Qt.
- SMPlayer — Qt multimedia player with extra features (CSS themes, YouTube integration, etc.) (Qt 5).
- 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.
Forks
- bomi — Powerful and easy to use multimedia player (Qt 5).

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/ALSA mixer controls since 0.18.1
This entry only applies if you are using pulseaudio for mpv (-ao=pulse
or ao=pulse
in mpv.conf
), or if you want to control your ALSA mixer volume with mpv.
Add the following to your ~/.config/mpv/input.conf
to make volume changes work again from PulseAudio/ALSA to mpv and vice versa:
/ add ao-volume -2 SHIFT+* add ao-volume 2
Change the above to whatever volume keys you use.
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 profile=opengl
[1] if possible (opengl-hq
has sometimes huge CPU spikes when a video is read using this mode).
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 that uses 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 profile comes with a debanding filter that greatly reduces the amount of visible banding, blocking and other quantization artifacts, at the expensive of very slightly blurring some of the finest details. In practice, it's virtually always an improvement - the only reason to disable it would be for performance.
If it leads to bad performance, you can disable it easily.
~/.config/mpv/mpv.conf
profile=opengl-hq deband=no
The opengl-hq
profile defaults to the spline36
scaling filter for mid quality and speed. For the best quality video output, the manual states that if your hardware can run it, ewa_lanczossharp
is probably what you should use.
~/.config/mpv/mpv.conf
profile=opengl-hq scale=ewa_lanczossharp cscale=ewa_lanczossharp
Save position on quit
By default you can save the position and quit by pressing Shift+q
. The shortcut can be changed by setting
quit_watch_later
in the key bindings configuration file.
To automatically save the current playback position on quit, start mpv with --save-position-on-quit
, or add save-position-on-quit
to the 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=acompressor
.
Quickly cycle between aspect ratios
You can cycle between aspect ratios using Shift+a
from version 0.8.0 onwards.
Ignoring aspect ratio
You can ignore aspect ratio using --keepaspect=no
. To make option permanent, add line keepaspect=no
to configuration file.
Draw to the root window
Run mpv with --wid=0
. mpv will draw to the 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.
Hide GUI for video files
It may be useful to hide the GUI window for video files. This can be done by using --no-video
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"
.
Browser plugins#Multimedia playback 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 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, streamlink can be used to stream Twitch. If you want a GUI for launching these streams use streamlink-twitch-guiAUR. 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 --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
If you prefer best quality open codecs (VP9 and Opus), use:
ytdl-format="((bestvideo[vcodec^=vp9]/bestvideo)+(bestaudio[acodec=opus]/bestaudio[acodec=vorbis]/bestaudio[acodec=aac]/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 --start=00:01:30 --frames=1 /path/to/video/file --o=/path/to/screenshot.png
Screenshots will be saved in /path/to/screenshot.png.
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)
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
profile=xv
This VO is deprecated and will cause issues in recent versions of mpv, most noticeably is the osd looking very blurry.
It is possible to increase playback performance even more (especially on lower hardware), but this decreases the video quality dramatically in most cases.
The following options may be considered to increase the video playback performance:
~/.config/mpv/mpv.conf
vd-lavc-fast vd-lavc-skiploopfilter=<skipvalue> vd-lavc-skipframe=<skipvalue> vd-lavc-framedrop=<skipvalue> vd-lavc-threads=<threads>
Problems with window compositors
Window compositors such as KWin or Mutter can cause trouble for playback smoothness. In such cases, it may help to set x11-bypass-compositor=yes
to make mpv also disable window compositing when playing in windowed mode (if supported by the compositor).
With KWin compositing and hardware decoding, you may also want to set x11-bypass-compositor=no
to keep compositing enabled in fullscreen, since reanabling compositing after leaving fullscreen may introduce stutter for a period of time.
