The only way to make it work is downgrade the software to(2021-10-04 version) : sudo flatpak update --commit=dcb66cdec7db7aa9f84e7f33614d26d34ec1aa277fa12c1ca6c98b8e4a4a2c52 com.obsproject.Studio

This sounds the new PipeWire in the runtime being incompatible with 0.3.19, which was also mentioned here (and similar looking logs): https://github.com/flathub/org.chromium.Chromium/pull/161#issuecomment-936304040

Could OBS try to ensure backwards compatbility as discussed here?

[columbarius]

https://github.com/obsproject/obs-studio/pull/5585 was merged into OBS and will be available in the next release. If anyone wants to test it a followup MR containing these changes creates a flatpak bundle (https://github.com/obsproject/obs-studio/actions/runs/1513737886).

[develroo]

Just wanted to chime in here too. Debian 11 testing Pipewire 0.3.40 On Gnome 41.1 Wayland and video capture of applications/windows no longer is an option.

[vchernin]

@develroo could you please test OBS CI's Flatpak bundle? Go to https://github.com/obsproject/obs-studio/actions/runs/1513737886, download and unzip the OBS Studio artifact, and then install the Flatpak bundle there.

If that still doesn't work, the next thing to test would be: https://github.com/obsproject/obs-studio/pull/5616

[develroo]

I did that. No joy alas.

They seem to be asking for people with older versions of pipewire. As I described I am on Debian Testing with a relatively recent version of pipewire and still facing the same issues of no capture windows being present. The verbose output shows that pipewire-window-capture-source cannot be found but previously it could, otherwise I would not have been able to define it in the first place.

I don't mind testing builds or giving debugging data back. Just not sure were to begin with this as there are no obvious errors being shown.

[vchernin]

Ah, I mistakenly though you were using an older version of PipeWire, my bad sorry. Indeed 0.3.40 is recent and those PRs shouldn't really apply much.

Is this a recent regression? Did it work with 0.3.39? Are xdg-desktop-portal-gnome and xdg-desktop-portal installed?

I see:

info: [pipewire] No captures available
[...]
error: Source ID 'pipewire-window-capture-source' not found

but that doesn't help much...

[vchernin]

Another question, are you on Debian 11 or Debian Testing? You mentioned both, I believe 11 ships with 0.3.19?

[develroo]

Debian Testing. I am an IT consultant and run Debian professionally, but this is my personal laptop, and so I am happy to run testing and give feedback

So to reiterate.

5.15.0-2-amd64 #1 SMP Debian 5.15.5-1 (2021-11-26) x86_64 GNU/Linux Pipewire 0.3.40-2 Wayland 1.19.0-2+b1 Gnome 41.1-1 Flatpak 1.12.2

Anything else I can do to help diagnose the issue?

[columbarius]

@develroo Do you have xdg-desktop-portal{,-gnome,-gtk} installed? The log has an error that the portal interface doesn't announce screencast capabilities.

[develroo]

Ahha! Your hunch was correct. xdg-desktop-portal-gnome was not installed by default?! How odd. I installed it manually, and now the options to capture windows via v4l2 or pipewire appear.

I suspect this is an issue with the Debian packaging issue because even pulling in the distro version does not have that dependency.

I wonder how we can address this issue with the flatpak build? Is there a way to include it independent of the desktop environment?

Anyway, thanks. Seems to be working now so that is a relief and incidentally it fixed Kooah issue as well. So I will drop that pearl of wisdom in there too.

Thanks.
