mpv é um reprodutor de mídia baseado no Mplayer e o agora defazado mplayer2. Ele suporta uma grande variedade de formatos de arquivos de vídeo, codecs de áudio e vídeo, e tipos de legenda. Uma lista detalhada (porém, admite-se, incompleta) das diferenças entre o mpv e os outros reprodutores mencionados anteriormente pode ser encontrada aqui.

## Instalação

Instale o pacote mpv ou mpv-gitAUR para a versão de desenvolvimento.

### Frontends

Veja List of applications/Multimedia#mpv-ased.

## Configuração

O mpv já vem com bons padrões iniciais que devem funcionar bem com computadores com placas de vídeo fracas/antigas. No entanto, se você tem um computador com uma placa de vídeo um pouco mais moderna, mpv permite que você faça uma configuração mais minuciosa para atingir uma melhor qualidade de vídeo (limitada apenas pela capacidade da sua placa de vídeo). Para fazer isso, será necessário criar apenas alguns arquivos de configuração (já que, por padrão, eles não existem).

Nota: Arquivos de configuração são lidos por todo o sistema (system-wide) em `/etc/mpv/` e por usuário (per-user) em `~/.config/mpv/` (a menos que a environment variable `XDG_CONFIG_HOME` esteja definida}, de modo que configurações por usuário sobrescrevem configurações por todo o sistema, e todas essas são sobrescritas pelas configurações feitas na linha de comando. A configuração de usuário específico é sugerida já que pode necessitar de tentativa e erro.

Para te ajudar a começar, mpv dispões de um modelo de configuração com as opções padrões. Copie-os para utilizá-los como um ponto de partida.

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

`mpv.conf` contem a maior parte das opções do mpv, `input.conf` contém atalhos de teclado. Leia os dois para ter uma ideia de como funcionam e quais opções estão disponíveis.

### Opções gerais

Adicione as seguintes opções em `~/.config/mpv/mpv.conf`.

#### Opções de legendas

Ativar a procura aproximada:

    sub-auto=fuzzy

Mudar a fonte:

    sub-font="fontName"

Ativar o negrito nas legendas para melhorar a leitura:

    sub-bold=yes

#### Configurações para alta qualidade

Por padrão, mpv utiliza opções que tentam equilibrar a qualidade e a performance da reprodução. Há também outras duas opções predefinidas disponíveis: `fast` para performance máxima e `high-quality` para uma renderização com qualidade superior. Você pode aplicar um perfil específico utilizando a opção `--profile--name` e inspecionar o conteúdo deste perfil utilizando `--show--profilename`.

    profile=high-quality

Estatísticas em tempo real mostrando a performance do mpv podem ser ativadas com a tecla `i`. Essa função é muito útil para ter certeza que seu hardware pode acompanhar suas configurações e para comparar diferentes confgurações.

Essas últimas duas opções são um pouco mais complicadas. `video-sync=display-resample` fazem com que o áudio e o vídeo dessincronizem, então invés de perder quadros, o áudio será ressampleado (uma pequena mudança no tom do áudio é comumente menos notável do que perdas de quadros). A wiki do mpv tem um artigo detalhado sobre isso intitulado Sincronização de Monitor (disponível somente em Inglês). `interpolation` faz com que movimentos apareçam mais suaves no seu monitor mudando o modo em que os quadros são apresentados, fazendo com que a taxa de quadros da mídia se adeque melhor à taxa de quadros do seu monitor (o que não deve ser confundido com a técnica SVP que realmente converte seu vídeo para 60fps). A wiki do mpv tem um artigo detalhado sobre esse assunto intitulado Interpolação (disponível somente em Inglês) porém essa função também é comumente conhecida como smoothmotion (em Português movimento suave).

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

Nota: Se NVIDIA Optimus estiver sendo usado, a linha `video-sync=display-resample` pode fazer com que o vídeo seja acelerado. Isso também completamente quebra a passagem de quadros em alguns sistemas, aparentemente fazendo com que a interpolação não funcione de modo algum.

Além disso ainda há muito o que você pode fazer, mas as coisas ficam mais complicadas, necessitam de placas de vídeo mais potentes, e estão em constante desenvolvimento. Fazendo uma breve exemplificação, é possível carregar shaders especiais que produzem técnicas exóticas de dimensionamento e nitidez incluindo algumas que utilizam redes neurais profundas treinadas em imagens (tanto para conteúdos do mundo real ou animações). Para aprender mais sobre isso, veja o conteúdo disponível na Wiki do mpv, em particular a Sessão de shaders de usuário.

Há também muitas outras opções que você pode achar interessantes. É muito recomendado dar uma olhada em mpv(1). Também é aconselhável rodar o mpv pela linha de comando para observar a presença de mensagens de erro sobre a configuração.

#### Perfís customizados

Em `mpv.conf` é possível criar perfís que são essencialmente só "grupos de opções" com as quais você pode:

- Rapidamente mudar entre diferentes configurações sem precisar modificar o arquivo de configuração.
- Criar perfis específicos para conteúdos específicos.
- Agrupar perfis para que você possa fazer um perfil mais sofisticado feito de outros perfis simples.

É fácil criar um perfil. A área no topo de `mpv.conf` é chamada de nível superior. No entanto, assim que você definir um perfil ao escrever seu nome entre colchetes, toda opção escrita abaixo dele (até que você defina um novo perfil) será considerada parte daquele perfil. Aqui está um exemplo de `mpv.conf`:

    profile=meuperfil2        #Área de nível superior, carregar meuperfil2
    ontop=yes                 #Sempre no topo

    [meuperfil1]              #Um perfil simples, a área de nível superior termina aqui

    profile-desc="um perfil"  #Descrição opcional do seu perfil

    fs=yes                    #Começar em tela cheia

    [meuperfil2]              #Outro perfil simples

    profile=high-quality      #Um perfil padrão que já vem com o mpv

    log-file=~~/log           #Define a localização pra a escrita do arquivo de log, ~~/ é o mesmo que ~/.config/mpv

Há apenas duas linhas dentro da área do nível superior e existem dois perfis distintos definidos abaixo dela. Quando o mpv inicia, ele observa a primeira linha, carrega as opções em `meuperfil2` (o que significa que ele carrega as opções em `high-quality` e em `log-file=~~/log`) e finalmente ele carrega `ontop=yes` e termina a inicialização. Perceba que `meuperfil1` nunca é carregado já que nunca foi chamado na área de nível superior.

Alternativamente, você pode chamar o mpv através da linha de comando com:

    $ mpv --profile=meuperfil1 video.mkv

e ele ignoraria todas as opções exceto as do `meuperfil1`

##### Perfis automáticos

Alguns tipos de perfil serão carregados automaticamente baseado na extensão do arquivo ou no protocolo utilizado.

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

Esses perfis serão carregados para todos os arquivos com uma extensão compatível (para todos os arquivos .mpv e .gif respectivamente):

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

    [extension.gif]
    osc=no
    loop-file

Esse perfil será carregado automaticamente sempre que qualquer corrente de conteúdo http ou https forem reproduzidas (e.g. `mpv https://example.com/video.mp4`

    [protocol.https]
    speed=2
    keep-open

    [protocol.http]
    profile=protocol.https

Execute o comando `mpv --list-protocols` para ver os diferentes protocolos suportados pelo mpv.

### Atalhos de teclado

Os atalhos de teclado são fáceis de entender dado os exemplos em `/usr/share/doc/mpv/input.conf` e mpv(1) § COMMAND INTERFACE.

Adicione o seguinte exemplo em `~/.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

Para tentar reproduzir os atalhos MPC-HC no mpv, veja [1].

### Arquivos de configuração adicionais

Além disso existem mais alguns arquivos de configuração e diretórios que podem ser criados, dentre eles:

- `~/.config/mpv/script-opts/osc.conf` administra o Controle na Tela. Veja mpv(1) § ON SCREEN CONTROLLER para mais informações.
- `~/.config/mpv/scripts/script-name.lua` para scripts Lua. Veja um exemplo em [2].

Veja mpv(1) § FILES para informações sobre outros arquivos e diretórios.

## Scripts

O mpv tem uma grande variedade de scripts que podem estender a funcionalidade do reprodutor. Para isso, ele tem chamadas internas tanto para Lua quanto para JavaScript.

Scripts são tipicamente instalados ao colocá-los no diretório `~/.config/mpv/scripts/` (você talvez tenha que criá-lo primeiro). Depois disso os scripts serão carregados automaticamente quando o mpv inicia (esse comportamento pode ser alterado com outra opção do mpv). Alguns scripts vêm com seus próprios instaladores e instruções de configuração, então faça questão de conferir. Além disso, alguns scripts podem ser antigos, quebrados e não mantidos.

### 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).

JavaScript support is available in the mpv package, as well as some AUR packages, e.g. mpv-fullAUR and mpv-full-gitAUR.

### 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[3]:

    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.

### 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 [4] for a comparison of `loudnorm` and `dynaudnorm`. (Discuss in Talk:Mpv (Português))

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 [5] and [6] 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 `.bashrc`:

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

### 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

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.
