OS: Arch Linux

Great program. I was looking for a program that reproduces lists in gnu/linux but does not work the sound within OBS. (alsa, pulse, openAL they listen, but it doesn't work for the PipeWire transition)

Make with:

  cmake -B build \
  -DCMAKE_BUILD_TYPE=None \
  -DCMAKE_INSTALL_PREFIX='/usr' \
  -DCMAKE_INSTALL_LIBDIR=lib \
  -DLINUX_PORTABLE=OFF

But don't work pipewire...

Can you post a full obs log? Also you might need to restart the playback after changing to pipewire.

b4zz4 commented

Yeah, reboot many times. The video (OBS) appears in Pulse Audio and don't play or recorded in the transmission. Not even the level changes.
Player windows don't allowed to interact.

The interaction not working is an issue with libmpv, nothing I can do about it. I also still need an obs log. Also I meant restarting the playback, not rebooting, like this:

s.mp4

But the audio capture is done using the Desktop audio?

univrsal commented

It's the same when I use the builtin source:

s2.mp4

Sure, that with pipewire isn't working on me. It's mute.

univrsal commented

What do the source properties look like after loading the file? Can you select a different audio track in there?

b4zz4 commented

It seems deactivated in the "interact" but in the source it is chosen.

Maybe it's a mistake in my compilation that parameters use in cmake

univrsal commented

does it happen with all video files? Do you have one that you could upload?

I did tests with many, it seems he's trying to connect with jack only …

It is heard by the speakers but not within OBS

No clue what the issue is then
