OBS and Wayland, Missing Video Sources

Issues & Assistance KDE
1

Hi, I've been having an issue with OBS not displaying any sources (no monitors, no active windows) to select from. The output is current black as nothing is selected.

I've searched for fixes but the issues do not seem resolved. I've also seen that OBS has native Wayland support but I cannot get it working under my setup.

I don't use wayland, so my ability to help here will be limited. I'll assume you have qt5-wayland installed.

You should see Screen Capture (PipeWire) in add source dialog.

While looking into this a bit, the mention of QT_QPA_PLATFORM was thrown around. It seems in the code, they're attempting to set this, but can you confirm any attempt to manually set this if that source is not available?

If not, could you try in terminal export QT_QPA_PLATFORM=wayland
and then run obs in the same terminal?

If the source is still not there, or you already tried this, then pasting the output of the obs initialization may provide some clues as to what's going on.

I noticed firejail running in the output. I decided to run "firecfg --clean" to remove OBS from being firejailed. After that everything was fixed. Thank you for the heads up with running OBS in the terminal.

No problem, glad you figured it out. Happy streaming/recording to you.
