WebRTC screen share not working Wayland KDE Nvidia

revolution · 2023-01-27 21:32:32

Hello, Screen share/capture works perfectly fine on OBS Studio. However, on Chrome and Firefox, it just shows a black screen with a cursor that can be moved around, neither window share nor screen share is working properly on WebRTC. I am using pipewire and wireplumber.

OS: Arch Linux x86_64

CPU: AMD Ryzen 5 7600X (12) @ 4.700GHz

GPU: NVIDIA GeForce RTX 3070 | Nvidia DKMS drivers with DRM modeset enabled.

Chrome Debug (when launched from terminal):

Chrome has both WebRTC pipewire support enabled and Ozone set to wayland.

I have my SDDM also set to Wayland. Metadata API and dbus support are enabled in wireplumber. I am using pipewire-git version, same result using stable normal version.

I have been pulling my hair out for 3 days.
If you want any other logs, tell me. I can also post a video if you want.

EDIT 0: I have set my intergrated amd gpu off by using modprobe config
EDIT 1: I first thought the problem would be Nvidia Graphics, but OBS works fine. There are also not any latest questions about this on the internet, so might not be a bug in the given software. Probably something stupid I am looking pass.

I am encountering the same issue, did you manage to resolve it?

No, the issues are open at GitHub Nvidia and Pipewire Gitlab. No resolution thus far, Nvidia is going to remain like Nvidia.
