feature request: pipewire audio output driver

[laichiaheng]

There is a PKGBUILD script in AUR which is mpv-pipewire, it allows pipewire to be the audio backend of MPV player.
Is there any way to do that with mpv-build-git in AUR?

Log file

Even if you think it's not necessary at first, it might help us later to find
possible issues. Make a log file made with -v -v or --log-file=output.txt, paste
it to https://0x0.st/ or attach it to the github issue, and replace this text
with a link to it.

Why are you asking questions about how to use Arch Linux packaging scripts on the mpv bug tracker?

If this is some patch file, just apply it during the appropriate step.

[laichiaheng]

So MPV hasn't officially supported pipewire yet?
I though I only need to enable some options.

[CounterPillow]

No, there is no pipewire AO in master.

If you read this package https://aur.archlinux.org/packages/mpv-pipewire/ you can see it adds its own patch. You can use that package or simply do as suggested and build mpv yourself. Keep in mind though, that this patch is experimental and mpv can already use pipewire through pipewire-pulse, with 0 configuration or changes needed on your end. This is how I use mpv.

[laichiaheng]

@LaserEyess Because I see lots of mistimed and delayed when playing videos with pipewire-pulse in Gnome, so I think maybe directly output to pipewire can have better result.
The delayed and mistimed issue seems will never be fixed by Gnome.

[LaserEyess]

I don't think that has anything to do with gnome, you should report that to pipewire with reproduction steps. Regardless you can still build mpv with that patch if you want, YMMV.

It's not pipewire specific issue, it happens to PulseAudio too.

[LaserEyess]

There are a couple of issues open about pulseaudio and stuttering see https://github.com/mpv-player/mpv/issues?q=is%3Aissue+label%3Aao%3Apulse+is%3Aopen. If none of these fit what you're seeing then open a new issue about it. Considering this happens with native pulse and pipewire-pulse it is likely a bug in mpv's pulse backend.

I forgot to disable my config profile, here is the

In Gnome:

mpv with pipewire-pulse: frame delayed and mistimed.
mpv with pipewire patch: no vsync jitter and frame delayed and mistimed.

In Plasma:

mpv with pipewire-pulse: frame mistimed.
mpv with pipewire patch: everything works fine.

In pure Mutter:

mpv with pipewire-pulse: no jitter, slowly increase frame mistimed.
mpv with pipewire patch: no frame delayed, mistimed and jitter.

So It really seems to be PulseAudio issue?
Maybe I should open a new issue.

[laichiaheng]

Does MPV have any plan to support PipeWire directly in the near future?

[LaserEyess]

See #8569 and the PR I linked earlier. Someone will have to implement it but it is a known feature request.

He seems have no plan for submitting the pull request.

As you can see in the linked issue, some people are happy to use pulse or ALSA (lmao).
Anyway, I'm sure it won't be long before PipeWire support comes to mpv.

As for the issue matter: you can build mpv yourself, using your own PKGBUILD which you can customize however you wan't.

i added the pipewire patches myself to mpv-full-build-git aur build file. pipewire ao works really good.

I use paru as aur helper. Simple add the patches to the PKGBUILD file.
(~/.cache/paru/clone/mpv-full-build-git/PKGBUILD)
https://paste.aachen.ccc.de/?b2008594662fab09#AVjKR0iOt6Bvy3nyUd8kU1SNo3ffxouOD2rnVRvb4wI=
and commit the changes local (git add and commit, no push)

Every mpv update paru will rebase your local commits to the PKGBUILD.

[laichiaheng]

@monarc99 I have a question, what is the difference between mpv-full-build-git and mpv-build-git and mpv-full-git, I'm really confused.

[monarc99]

i think:

full: all codecs activated (and many dependencies)
build: compile ffmpeg + mpv
without build: only compile mpv against system ffmpeg

Added in #9587.

How is your experience with ao=pipewire and BT audio? For me, it sometimes seems to put the whole PipeWire audio server into a bad state that causes seconds of delay in all applications. It happens e.g. when mpv playback is running and I open the Plasma audio applet or start Firefox (but not 100% reproducible). Might of course also be an issue in PW itself, but it seems only mpv PW triggers it (ALSA and OpenAL are fine).

[laichiaheng]

@aufkrawall I rarely play videos and do other things with sound effect at the same time.
By the way, I use Gnome.
