[Pkg-utopia-maintainers] Bug#1072645: pipewire: Apps using pipewire broken

[Helge Kreutzmann]

Package: pipewire
Version: 1.0.7-1
Severity: important

I upgraded from stable to testing a few days ago. In stable all video
and audio applications worked as expected, e.g. vlc, mpv, cmus,
mpg123, ogg123 …

Now many apps don't. Some (like cmus) produce output, but e.g. vlc and
mpv do not. The only difference I could determine is using pipewire.
The effect is that the first video frame is shown, then the
application freezes/stops.

Examples:
helge at twentytwo:~/download/Video/View$ mpv Cher\ -\ If\ I\ Could\ Turn\ Back\ Time\ \(Official\ Video\)\ \[9n3A_-HRFfc\].webm
 (+) Video --vid=1 (*) (vp9 1920x1080 23.980fps)
 (+) Audio --aid=1 --alang=eng (*) (opus 2ch 48000Hz)
AO: [pipewire] 48000Hz stereo 2ch floatp
VO: [gpu] 1920x1080 yuv420p
AV: 00:00:00 / 00:04:05 (0%) A-V: -0.078 Dropped: 1
Exiting... (Quit)

pavucontrol only shows a dummy output.

I tried downgrading pipewire to the stable version, but this is not
possible (maybe rebuilding works, did not try).

To get mpv to work again, I read its man page and found the following
working command line:
mpv --audio-device=alsa/plughw:CARD=Generic_1,DEV=0 Cher\ -\ If\ I\ Could\ Turn\ Back\ Time\ \(Official\ Video\)\ \[9n3A_-HRFfc\].webm

Please tell me which additional information you need to track this
down.
