OBSstudio: No creen capture device for pipewire XSHM only

Erdie

Within OBSstudio when I try to capture the screen, pipewire and XSHM are offered. XSHM works but when I try use pipewire, no screen are visible.

On my system pipewire is running. Is there any further configuration needed to use the screen sharing capabilities? Currently my sound system is running on pipewire flawless.

thanks
-Erdie

Maybe this only works with a wayland based desktop? I am not sure ..

This has been a bit of a mystery to me, too, even as the current maintainer of 'media-video/obs-studio'.

I haven't used PipeWire myself, so that's probably a part of the problem.

Looking around, it still don't seem like it has been clearly documented upstream either.

Also, trying it again now myself, I can't get any PipeWire sources to appear, audio or video. It does look like audio capture might be only available via an external plug-in, and indeed, video only on Wayland.

Here's a is a pull request regarding audio capture:

https://github.com/obsproject/obs-studio/pull/6207

In that particular PR, there is this comment:

"Note: Running OBS with OBS_USE_EGL=1 allows PipeWire capture being loaded under X11."

I already see 'info: Using EGL/X11' regardless, and adding that does not seem to have any effect here.

Here is a GitHub discussion regarding the overall status of OBS Studio PipeWire support:

https://github.com/obsproject/obs-studio/discussions/7998

In conclusion, I suppose I should add a 'wayland' dependency on 'pipewire' at least for the time being, unless someone else knows how to make use of it on X11...

Thank you! In the case that this doen´t work, it is not a big deal because I can do it without pipewire. But it would be exiting to give it a try if it would be possible. This is not a problem at all.
