Screen Capture Only Works On First Startup of The Graphical Session #10148

Expected Behavior

Every time I create a new screen capture source it should work.

Current Behavior

When I start up OBS for the first time for a graphical user session, screen capturing works as I would expect. If delete the screen capture source and try to recreate, or exit and start the OBS application again, all screen captures are a black screen.

Steps to Reproduce

In the attached OBS logs, I started OBS and screen capture works as expected, then I delete the source and recreate it and it is a black screen. The only fix is to log out of the graphical session and log back in.

Anything else we should know?

I am running hyprland/wayland.

Changing video encoder to "software" has no effect.

This happens on the Nixos OBS package or the OBS flatpak. The logs are from the OBS flatpak

The issue persists if I run with XWayland as well env -u WAYLAND_DISPLAY flatpak run com.obsproject.Studio. Screen capture with XWayland and using XSHM instead of pipewire will show the cursor, but the screen is still black.

tytan652 commented 9 months ago

There is a high chance that the issue is on the portal side sending a broken PipeWire stream.

Since you are using Hyprland, you should be using xdg-desktop-portal-hyprland to get a ScreenCast portal implementation and not xdg-desktop-portal-wlr.

For now I will just ask if you are actually using xdg-desktop-portal-hyprland and maybe check its issue tracker. If you are using xdg-desktop-portal-wlr, switch to xdg-desktop-portal-hyprland.

Yes I am using xdg-desktop-portal-hyprland

I did find that there is a broken pipe when trying to recreate the source
