mpv is a media player based on MPlayer and the now unmaintained mplayer2. It supports a wide variety of video file formats, audio and video codecs, and subtitle types. A detailed (although admittedly incomplete) list of differences between mpv and the aforementioned players can be found in [1].

## Installation

Install the mpv package.

### Front ends

See List of applications/Multimedia#mpv-based.

## Configuration

mpv comes with good all-around defaults that should work well on computers with weaker/older video cards. However, if you have a computer with a more modern video card, mpv allows you to do a great deal of configuration to achieve better video quality (limited only by the power of your video card). To do this, one only needs to create a few configuration files (as they do not exist by default).

Note Configuration files are read system-wide from `/etc/mpv/` and per-user from `~/.config/mpv/` (unless the environment variable `XDG_CONFIG_HOME` is set), where per-user settings override system-wide settings, all of which are overridden by the command line. User-specific configuration is suggested since it may require some trial and error.

To help you get started, mpv provides sample configuration files with default settings. Copy them to use as a starting point:

    $ cp -r /usr/share/doc/mpv/ ~/.config/

`mpv.conf` contains the majority of mpv's settings, `input.conf` contains key bindings. Read through both of them to get an idea of how they work and what options are available.

### General settings

Add the following settings to `~/.config/mpv/mpv.conf`.

#### Subtitle configurations

Enable fuzzy searching:

    sub-auto=fuzzy

Change font:

    sub-font="fontName"

Bold the subtitles to increase readability:

    sub-bold=yes

#### High quality configurations

By default, mpv utilizes settings that balance quality and performance. Additionally, two predefined profiles are available: `fast` for maximum performance and `high-quality` for superior rendering quality. You can apply a specific profile using the `--profile=name` option and inspect its contents using `--show-profile=name`.

    profile=high-quality

Live statistics showing how well mpv is performing can be brought up with the `i` key. It is very useful for making sure that your hardware can keep up with your configuration and for comparing different configurations.

These last two options are a little more complicated. `video-sync=display-resample` makes it so that if audio and video go out of sync, then instead of dropping video frames, it will resample the audio (a slight change in audio pitch is often less noticeable than dropped frames). The mpv wiki has an in depth article on it titled Display Synchronization. `interpolation` makes motion appear smoother on your display by changing the way that frames are shown so that the source framerate jives better with your display's refresh rate (not to be confused with SVP's technique which actually converts video to 60fps). The mpv wiki has an in depth article on it titled Interpolation though it is also commonly known as smoothmotion.

    profile=high-quality
    video-sync=display-resample
    interpolation

Note If NVIDIA Optimus is being used, the line `video-sync=display-resample` may cause video to be sped up. It also completely messes up frame pacing on some systems, seemingly preventing interpolation from working at all.

Beyond this, there is still a lot you can do, but things become more complicated, require more powerful video cards, and are in constant development. As a brief overview, it is possible to load special shaders that perform exotic scaling and sharpening techniques including some that actually use deep neural networks trained on images (for both real world and animated content). To learn more about this, take a look around the mpv wiki, particularly the user shader's section.

There are also plenty of other options you may find desirable as well. It is worthwhile taking a look at mpv(1). It is also helpful to run mpv from the command line to check for error messages about the config.

#### Custom profiles

In `mpv.conf` it is possible to create profiles which are essentially just "groups of options" with which you can:

- Quickly switch between different configurations without having to rewrite the file.
- Create special profiles for special content.
- nest profiles so that you can make more complicated profiles out of simpler ones.

Creating a profile is easy. The area at the top of `mpv.conf` is called the top level, any options you write there will kick into effect once mpv is started. However, once you define a profile by writing its name in brackets, every option you write below it (until you define a new profile) is considered part of that profile. Here is an example `mpv.conf`:

    profile=myprofile2        #Top level area, load myprofile2
    ontop=yes                 #Always on top

    [myprofile1]              #A simple profile, top level area ends here
    profile-desc="a profile"  #Optional description for profile
    fs=yes                    #Start in full screen

    [myprofile2]              #Another simple profile
    profile=high-quality      #A built in profile that comes with mpv
    log-file=~~/log           #Sets a location for writing a log file, ~~/ translates to ~/.config/mpv

There are only two lines within the top level area and there are two separate profiles defined below it. When mpv starts, it sees the first line, loads the options in `myprofile2` (which means it loads the options in `high-quality` and `log-file=~~/log`) finally it loads `ontop=yes` and finishes starting up. Note, `myprofile1` is never loaded because it is never called in the top level area.

Alternatively, one could call mpv from the command line with:

    $ mpv --profile=myprofile1 video.mkv

and it would ignore all options except the ones for `myprofile1`.

##### Automatic profiles

Certain types of profiles will be loaded automatically based on either the file extension or the protocol used.

These profiles will be loaded for all files with a matching file extension (for all .mkv and .gif files respectively):

    [extension.mkv]
    keep-open
    volume-max=150

    [extension.gif]
    osc=no
    loop-file

This profile will be loaded automatically whenever any http or https streams are played (e.g. `mpv https://example.com/video.mp4`):

    [protocol.https]
    speed=2
    keep-open

    [protocol.http]
    profile=protocol.https

Run `mpv --list-protocols` to see the different protocols supported by mpv.

### Key bindings

Key bindings are fairly straightforward given the examples in `/usr/share/doc/mpv/input.conf` and mpv(1) § COMMAND INTERFACE.

Add the following examples to `~/.config/mpv/input.conf`:

    shift+s         screenshot each-frame
    Shift+UP        seek  600
    Shift+DOWN      seek -600
    =               cycle video-unscaled
    -               cycle-values window-scale 2 3 1 .5
    WHEEL_UP        add volume 5
    WHEEL_DOWN      add volume -5
    WHEEL_LEFT      ignore
    WHEEL_RIGHT     ignore
    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
    Alt+BS          set video-zoom 0; set video-pan-x 0; set video-pan-y 0

For an attempt to reproduce MPC-HC key bindings in mpv, see [2].

### Additional configuration files

In addition there are a few more configuration files and directories that can be created, among which:

- `~/.config/mpv/script-opts/osc.conf` manages the on Screen Controller. See mpv(1) § ON SCREEN CONTROLLER for more information.
- `~/.config/mpv/scripts/script-name.lua` for Lua scripts. See [3] for an example.

See mpv(1) § FILES for information on other files and directories.

## Scripts

mpv has a large variety of scripts that extend the functionality of the player. To this end, it has internal bindings for both Lua and JavaScript.

Scripts are typically installed by putting them in the `~/.config/mpv/scripts/` directory (you may have to create it first). After that they will be automatically loaded when mpv starts (this behavior can be altered with other mpv options). Some scripts come with their own installation and configuration instructions, so make sure to have a look. In addition some scripts are old, broken, and unmaintained.

### JavaScript

JavaScript (ES5 via MuJS) has been supported as an mpv scripting language since 2014. Currently only a few scripts are available, but documentation exists at mpv(1) § JAVASCRIPT for anyone interested in making their own.

To get started, drop a script with a `.js` extension in the mpv `scripts` directory, e.g.:

    ~/.config/mpv/scripts/fullscreen-off-on-pause.js

    function onPauseChange (prop, enabled) {
        if (enabled) {
            mp.set_property('fullscreen', 'no')
        }
    }

    mp.observe_property('pause', 'bool', onPauseChange)

For more details, e.g. on using `require` to load CommonJS modules, see mpv(1) § CommonJS modules and require(id).

### Lua

The development of mpv's Lua scripts is documented in mpv(1) § LUA SCRIPTING with examples in TOOLS/lua, which are installed to `/usr/share/mpv/scripts`.

For example, you can enable the builtin script to automatically crop videos with black bars:

    $ ln -s /usr/share/mpv/scripts/autocrop.lua ~/.config/mpv/scripts

#### mpv-ytdlAutoFormat

mpv-ytdlautoformat is a Lua script to auto change ytdl-format for Youtube and Twitch or the domains you desire, to 480p or the quality you desire.

#### mpv-webm

mpv-webm (or simply webm) is a very easy to use Lua script that allows one to create WebM files while watching videos. It includes several features and does not have any extra dependencies (relies entirely on mpv).

#### ytdl-preload

ytdl-preload is a Lua script to preload the next ytdl-link in your playlist.

Note The script is still in active developing process.

### C

#### mpv-mpris

The C plugin mpv-mpris allows other applications to integrate with mpv via the MPRIS protocol. For example, with mpv-mpris installed, kdeconnect can automatically pause video playback in mpv when a phone call arrives. Another example is buttons (play\pause etc) on bluetooth audio-devices.

To use the plugin, install mpv-mpris.

## 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.

The mpv package now enables Vapoursynth support by default.

### SVP 4 Linux (SmoothVideoProject)

SmoothVideoProject SVP is a program that is primarily known for converting video to 60fps. It is free [as in beer] and full featured for 64bit Linux (costs money for Windows and OS X and is incompatible with 32bit Linux).

It has three main features and each one can be disabled/enabled as one chooses (you are not forced to use motion interpolation).

1. Motion interpolation (youtube video) - An algorithm that converts video to 60fps. This creates the somewhat controversial "soap opera effect" that some people love and others hate. Unfortunately, the algorithm is not perfect and it also introduces more than its share of weird artifacts. The algorithm can be tuned (via a slider) for either performance or quality. It also has some artifact reduction settings that interpolate actual frames with the generated frames reducing the noticeability of the artifacts. The framerate detection can be set to automatic or manual (manual seems to resolve performance issues for some users).
2. Black bar lighting (youtube video) - If the image has an aspect ratio that produces black bars on your display, SVP will illuminate the black bars with "lights" generated by the content on the screen. It has some amount of customization, but the defaults are pretty close to optimal.
3. LED ambient lighting control (youtube video) - Has the ability to control LED ambient lighting attached to your television.

Once you have mpv compiled with Vapoursynth support, it is fairly easy to get SVP working with mpv. Simply install svp-binAUR, open the SVP program to let it assess your system performance (you may want to close other programs first so that it gets an accurate reading), and finally add the following mpv profile to your mpv.conf[4]:

    mpv.conf

    [svp]
    input-ipc-server=/tmp/mpvsocket     # Receives input from SVP
    hr-seek-framedrop=no                # Fixes audio desync
    watch-later-options-remove=vf       # Do not remember SVP's video filters

    # Can fix stuttering in some cases, in other cases probably causes it. Try it if you experience stuttering.
    #opengl-early-flush=yes

Then, in order to use SVP, you must have the SVP program running in the background before opening the file using mpv with that profile. Either do:

    $ mpv --profile=svp video.mkv

or set `profile=svp` in the top-level portion of the mpv configuration.

If you want to use hardware decoding, you must use a copy-back decoder since normal decoders are not compatible with Vapoursynth (choose a `hwdec` option that ends in `-copy`). For instance:

    hwdec=auto-copy
    hwdec-codecs=all

Either way, hardware decoding is discouraged by mpv developers and is not likely to make a significant difference in performance.

## Tips and tricks

### Picture

#### Hardware video acceleration

See Hardware video acceleration.

Hardware accelerated video decoding is available via the `--hwdec=API` option. For a list of all supported APIs and other required options, see mpv(1) § hwdec.

To make it permanent (for example when playing videos from a desktop environment), add it to the configuration file:

    ~/.config/mpv/mpv.conf

    hwdec=auto

To allow CPU processing with video filters, choose a `*-copy` API.

Use the keyboard shortcut `Ctrl+h` while a video is running to toggle hardware decoding.

To troubleshoot hardware acceleration, adjusting the logging levels (see mpv(1) § msg-level) may be necessary. For instance, `--msg-level=vd=v,vo=v,vo/gpu/vaapi-egl=trace` enables the following:

- Verbose messages from the video decoder (`vd`) and video output (`vo`) modules.
- Even more detailed trace messages for the module responsible for video decoding. Here, after running mpv once without any log levels adjusted, the module of interest was empirically determined to be `vo/gpu/vaapi-egl`.

#### Quickly cycle between aspect ratios

You can cycle between aspect ratios using `Shift+a`.

#### Ignoring aspect ratio

You can ignore the aspect ratio using `--keepaspect=no`. To make the option permanent, add the line `keepaspect=no` to the 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 the application window

To show the application window even for audio files when launching mpv from the command line, use the `--force-window` option. To make the option permanent, add the line `force-window=yes` to the configuration file.

#### Disable video output

To disable video output when launching from command line, use the `--vid=no` option, or its alias, `--no-video`.

#### Terminal video

- `--vo=tct` "Color Unicode art video output driver that works on a text console."
- `--vo=caca` "Color ASCII art video output driver that works on a text console." libcaca support has been disabled on Arch due to vulnerabilities (see FS#70962) and has not been added back in as its upstream is inactive: install mpv-fullAUR.
- `--vo=kitty` "Using Kitty protocol for video output that works on all terminals that support this protocol"

### Audio

#### Volume is too low

Set `volume-max=value` in your configuration file to a reasonable amount, such as `volume-max=150`, which then allows you to increase your volume up to 150%, which is more than twice as loud. Increasing your volume too high will result in clipping artefacts. Additionally (or alternatively), you can utilize dynamic range compression with `af=acompressor`.

#### Specify an audio output

Run the following command to get a list of available audio output devices

    $ mpv --audio-device=help

Then add one to `~/.config/mpv/mpv.conf`. For example:

    audio-device=alsa/hdmi:CARD=NVidia,DEV=1

#### HD Audio passthrough

To enable HD audio codecs like TrueHD and DTS-MA to passthrough to an AV receiver, add the following to `~/.config/mpv/mpv.conf`

    audio-spdif=ac3,eac3,dts-hd,truehd

#### Volume normalization

This article or section needs expansion.

Reason: Add little more details about the available filters, see [5] for a comparison of `loudnorm` and `dynaudnorm`. (Discuss in Talk:Mpv)

Different sources may have different or inconsistent loudness, so mpv users may need to configure automatic volume normalization. For example:

    ~/.config/mpv/input.conf

    n cycle_values af loudnorm=I=-30 loudnorm=I=-15 anull

This binds the key `n` to cycle the audio filter settings (`af`) through the specified values:

- `loudnorm=I=-30`: loudnorm setting with `I=-30`, soft volume, might be suitable for background music
- `loudnorm=I=-15`: louder volume, might be good for the video currently in view
- `anull`: reset audio filter to null, i.e., disable the audio filter

Note Binding a key does not change the default audio filter. To change the default, add e.g. `af=loudnorm=I=-30` to the main configuration file.

Audio filtering in mpv is provided by the FFmpeg backend. See Wikipedia:EBU R 128 and ffmpeg loudnorm filter for details.

See also upstream issues [6] and [7] which mention different options.

#### Improving mpv as a music player with Lua scripts

This blog post introduces the music.lua script, which shows how Lua scripts can be used to improve mpv as a music player.

### 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.

#### Save position of a playlist and pause on next file

A playlist could simply be a list of files, see mpv(1) § playlist. To play a playlist and remember its position:

    $ mpv --save-position-on-quit --pause --reset-on-next-file=pause --playlist=/path/to/playlist

With the option `--pause` mpv will start in paused state and `--reset-on-next-file=pause` will reset the pause mode when switching to the next file.

### Play a DVD

mpv does not support DVD menus. To start the main stream with the longest title of a video DVD, use the command:

    $ mpv dvd://

An optional title specifier is a number (starting at 0) which selects between separate video streams on the DVD:

    $ mpv dvd://[title]

DVDs which have been copied on to a local file system (by e.g. the dvdbackup tool) are accommodated by specifying the path to the local copy: `--dvd-device=PATH`.

See the following desktop file example for playing DVDs from a local file system:

    [Desktop Entry]
    Type=Application
    Name=mpv Media Player DVD
    GenericName=Multimedia player
    Comment=Play movies and songs
    Icon=mpv
    Exec=mpv dvd:// --player-operation-mode=pseudo-gui --force-window --idle --dvd-device=%f
    Terminal=false
    Categories=AudioVideo;Audio;Video;Player;TV;
    # (MimeType and X-KDE-Protocols omitted, see original mpv.desktop file)

By replacing the Exec line with

    Exec=mpv dvd://0 dvd://1 dvd://2 dvd://3 dvd://4 dvd://5 dvd://6 dvd://7 dvd://8 dvd://9  --player-operation-mode=pseudo-gui --force-window --idle --dvd-device=%f

the mpv player will queue DVD title 0 to 9 in the playlist, which allows the user to play the titles consecutively or jump forward and backward in the DVD titles with the mpv GUI.

Install libdvdcss, to fix the error:

    [dvdnav] Error getting next block from DVD 1 (Error reading from DVD.)

### 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.

### Reproducible screenshots

The screenshot template option can include the precise timecode (HH:MM:SS.mmm) of the screenshoted frame. The meaningful filename makes it easy to know the origin of the screenshot. It can be set like this:

    ~/.config/mpv/mpv.conf

    screenshot-template="%F - [%P] (%#01n)"

This expands to `filename - [HH:MM:SS.mmm] (number).jpg`. Example result:

    Gunsmith Cats/
    ├── Gunsmith Cats Ep. 01 - [00:00:50.217] (1).jpg
    ├── Gunsmith Cats Ep. 01 - [00:22:55.874] (1).jpg
    ├── Gunsmith Cats Ep. 01 - [00:22:55.874] (2).jpg
    └── Gunsmith Cats Ep. 02 - [00:15:05.778] (1).jpg

A bonus is it sorts nicely because alphabetically, the timecode is sorted within the episode number.

See mpv(1) § screenshot-template for more information.

### 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.

### Streaming

#### Twitch.tv streaming over mpv

If yt-dlp or youtube-dlAUR is installed, mpv can directly open a Twitch livestream.

Alternatively, see Streamlink#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!~='vp0?9']+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 stream audio from your terminal emulator with `yta search terms`, put the following function in your shell startup file:

    function yta() {
        mpv --ytdl-format=bestaudio ytdl://ytsearch:"$*"
    }

#### V4L2 AV capture device

For example, live streaming from an USB webcam or from an USB HDMI capture device.

Find the V4L2 device's video device node:

    $ v4l2-ctl --list-devices

    HDMI Capture: HDMI Capture (usb-0000:07:00.1-2):
    	/dev/video2
    	/dev/video3
    	/dev/media1

Usually this ist the first listed `/dev/video*` node, here `/dev/video2`.

Then, find the name of the capture device's PulseAudio source:

    $ pactl list short sources | grep --invert-match --regexp=.monitor

    (...some devices omitted...)
    8750	alsa_input.usb-XF_HDMI_Capture_20000130041415-02.iec958-stereo	PipeWire	s16le 2ch 48000Hz	SUSPENDED

That name would here be `alsa_input.usb-XF_HDMI_Capture_20000130041415-02.iec958-stereo`.

Now you can launch MPV with this command:

    $ mpv --audio-file=av://pulse:alsa_input.usb-XF_HDMI_Capture_20000130041415-02.iec958-stereo -- av://v4l2:/dev/video2

### System integration

#### Opening video links from the KDE clipboard

If youtube-dlAUR or yt-dlp is installed and KDE Plasma is being used, it is possible to create a custom action in the KDE clipboard to conveniently play links from video sharing sites.

1. Open the clipboard configuration menu (typically by right-clicking its icon in the system tray) and go to the Actions tab.
2. Click Add Action then enter a regular expression to detect the sites you would like to play video from (e.g. `^http.+(youtu|twitch)` to detect YouTube and Twitch URLs).
3. Click Add Command, under Command enter `mpv %s` and under Description enter `mpv`.

Now, you can play video links from your clipboard in mpv by pressing `Ctrl+Alt+r` and selecting mpv from the context menu. You may need to go to Advanced Settings and remove Firefox from the section Disable Actions for Windows of Type WM_CLASS.

## Troubleshooting

### General debugging

If you are having trouble with mpv's playback (or if it is flat out failing to run) then the first three things you should do are:

1. Run mpv from the command line (the -v flag increases verbosity). If you are lucky there will be an error message there telling you what is wrong.
   `$ mpv -v video.mkv`
2. Have mpv output a log file. The log file might be difficult to sift through but if something is broken you might see it there.
   `$ mpv -v --log-file=./log video.mkv`
3. Run mpv without a configuration. If this runs well then the problem is somewhere in your configuration (perhaps your hardware cannot keep up with your settings).
   `$ mpv --no-config video.mkv`

If mpv runs but it just does not run well then a fourth thing that might be worth taking a look at is the live statistics (with `i`) to see exactly how it is performing.

### 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 an 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 (Xorg only) video output device may help:

    ~/.config/mpv/mpv.conf

    vo=xv

Note This is the most compatible VO on X, but may be low-quality, and has issues with OSD and subtitle display.

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

As described in mpv(1) § Window, mpv by default disables any active window compositor while in fullscreen mode. This is done to prevent potential performance issues during playback.

For window compositors such as KWin or Mutter, it can be advantageous to disable window compositing even while in windowed mode. This can be achieved by using setting the `x11-bypass-compositor=yes` option.

There are two disadvantages to disabling compositing:

- Re-enabling compositing may introduce stutter for a period of time, particularly if using KWin compositing.
- Any effects provided by compositing will be temporarily unavailable (until mpv re-enables it), which in Plasma prevents the default app switcher from working.

To sidestep these issues, you can try keeping your compositor enabled with `x11-bypass-compositor=no`

### No volume bar, cannot change volume

Spin the mouse wheel over the volume icon.

### GNOME Blank screen (Wayland)

mpv may not suspend GNOME's Power Saving Settings if using Wayland resulting in screen saver turning off the monitor during video playback. A workaround is to add `gnome-session-inhibit` to the beginning of the `Exec=` line in `mpv.desktop`.

In order to inhibit the screensaver only during playback, use mpv_inhibit_gnomeAUR. Alternatively, a mpv lua script based on `gnome-session-inhibit` may be used.

Tip The `io.mpv.Mpv` flatpak app already includes the mpv_inhibit_gnome plugin.

### Cursor theme not respected under GNOME Wayland

### Error message about missing CUDA libraries on AMD GPUs

While using VAAPI hardware acceleration on AMD GPUs on versions v0.34.1 and older, you may see a persistent error message saying `Cannot load libcuda.so.1`. This can be suppressed by setting `gpu-hwdec-interop=vaapi`.

This issue has been fixed upstream in pull request #9842.

### Unable to play audio if PipeWire is masked

If mpv crashes or fails to play audio on systems where PipeWire is masked, reporting no outputs or broken pipe, set the `--ao` option to match your environment. Set it in `mpv.conf` for persistent configuration.

### mpv will not start playing a DVD from file

If mpv will not play a DVD from file in plain VIDEO_TS/VOB structure, there could be a problem with the restore playback position function. Try either cleaning `.config/mpv/watch_later` folder, or start mpv with the `no-resume-playback` option and/or set the `save-position-on-quit=no` option.

### Fix stuttering after resuming playback from pause

If video is stuttering with PulseAudio, try the `pulse-latency-hacks` option discussed at mpv(1) § --pulse-latency-hacks:

    ~/.config/mpv/mpv.conf

    pulse-latency-hacks=yes

### Screen sharing cannot capture audio from mpv

For example, when you share mpv into Discord with Discord's "Share a window" functionality and specify that audio should be shared as well, yet Discord fails to capture mpv's audio.

This has been observed when the system uses PipeWire. Then, by default, mpv uses its `pipewire` audio output driver, which may cause this issue.

The solution is to switch mpv to its `pulse` audio output driver. This should be uncritical as PipeWire also implements PulseAudio's audio API.

When running mpv from the command line this can be done by supplying the `--ao=pulse` option.

To permanently make mpv use its PulseAudio audio output driver you can put an `ao=pulse` text line into an mpv configuration file.
