Expected Behavior
The Pipewire screen capture source should be working.
Current Behavior
After installing my new GPU, a Radeon RX 7900 XT, screen capture sources are not showing any images at all. I can select and move it in the UI, but it's a fully transparent rectangle.
Steps to Reproduce
- Open up OBS on a scene with a Pipewire screen capture source.
- Look at the scene preview.
Anything else we should know?
I reproduced this issue with both the OBS packaged by Arch Linux as well as with the Flatpak (both obs-studio-29.0.0 using mesa-22.3.3 and llvm-libs 15.x). I'm on Wayland, my compositor is Sway 1.8.
The relevant error message is:
10:06:44.014: [pipewire] Renegotiating stream
10:06:44.030: Cannot create EGLImage: EGL failed to allocate resources for the requested operation.
This suggests that the issue might exist within Pipewire, Sway or somewhere else in the OpenGL stack. I double-checked Pipewire-based screensharing in my Jitsi instance (using both Firefox and the Webkit-based Qutebrowser), and that's working perfectly fine. But obviously, it's still possible that OBS is trying to capture the screen using a different set of parameters. Unfortunately, the screen capture source does not offer me any configuration parameters to tinker with.
Can reproduce, same GPU. I'm running LLVM 15 with mesa 22.3.2 and on Hyprland instead of Sway (still wlroots).
I'm not using the flatpak version
edit: Void Linux (glibc)
Screen capture doesn't work for me either. I am using Arch Linux with mesa-git, hyprland-git and the xdg-desktop-portal-hyprland-git. Webcord can use pipewire screen sharing without issue. Opening obs from a terminal I get the following error message:
error: Cannot create EGLImage: EGL failed to allocate resources for the requested operation.
info: [pipewire] Renegotiating stream
error: Cannot create EGLImage: EGL failed to allocate resources for the requested operation.
info: [pipewire] Renegotiating stream
...
@simvux @Teddy-Kun Thanks for your confirmations! Since all of us are on wlroots compositors, I have tested with other another Wayland compositor now. And sure enough, screen capture into OBS via PipeWire works fine in a Plasma session.
I'm only speaking as a user, so don't take this as me saying that wlroots is at fault here, but I think it makes sense to make the wlroots devs aware as well. I tried opening an issue in their tracker, but my user account needs to be approved first. If one of you has an account there that works, please report this issue over there as well. Otherwise I'll do it when my account gets approved.
mesa-22.3.3 and llvm-libs 15.x
As far as I understand, that MESA driver requires LLVM 15, and the KDE 6.4 runtime uses LLVM14 and cannot switch to LLVM15. We would need to wait for a KDE runtime that uses LLVM15 to be available.
i cannot replicate this with intel (old/new) on sway. Please provide an obs log if you are affected instead of trying to give a description of your hardware.
Also just a note, for the continual renegotiation that presents as:
error: Cannot create EGLImage: EGL failed to allocate resources for the requested operation.
info: [pipewire] Renegotiating stream
error: Cannot create EGLImage: EGL failed to allocate resources for the requested operation.
info: [pipewire] Renegotiating stream
This suggests that OBS and your compositor are unable to agree on a dmabuf format. On AMD there may be hundreds of formats to check which might take some time at 60fps. You should probably try and extract the full set of modifiers offered by your compositor against what obs can load. If you can run obs with PIPEWIRE_DEBUG=4 ./obs that should provide sufficient logging to diagnose the negotiation failure. This log will be extremely large.
If I launch chromium (native wayland version) then I seem to also get EGL errors that may or may not be related.

Chromium does work fine however. So it's probably fallbacking to some alternate form of rendering.
But I'm thinking this could be some bug in libglvnd or mesa or something causing these errors, not necessarily OBS.
Could someone who gets EGL errors in OBS try to replicate this?
I have the same issue on the same hardware. 7900XT on Fedora 37. I use the flatpak version. I cannot spot anything in the logs:

@columbarius Just tried compiling your branch from the PR of obs and master of xdg-desktop-portal-wlr and can confirm this works! Big thanks.
side note; to get OBS to compile, i had to comment out the line obs-studio/plugins/obs-ffmpeg/obs-ffmpeg-mpegts.c:214. Because the property codec is deprecated and OBS's build has -Werror=deprecated-declarations
Hm, interestingly the error still appears 3 or 4 times when the stream starts. But then stops and visually everything works.
Going into settings does cause a segmentation fault but I suspect that's because of the hack I did to get it to compile mentioned above :p

Those errors are expected. Format negotiation has options which can only be fixed by testing. As such OBS tries to import a buffer and if that fails it will send this information back to the producer. Those are the errors you see.

If this happens again, please provide a trace :)
The upgrade to xdg-desktop-portal-wlr-0.7.0 resolves this issue for me, so I'm going to assume that https://github.com/emersion/xdg-desktop-portal-wlr/pull/260 was what did the trick. @columbarius Thank you very much for your help!
