Black screen on capturing screen with pipewire

zeio · Nov 20, 2023

Hey, I am using `gentoo` with `hyprland`, trying to set up screen capturing through `pipewire`. Here is a strange error I get when I add `screen capture pipewire` to the scene. The following message is repeatedly printed in the obs log:

Code:

info: [pipewire] Negotiated format:
info: [pipewire]     Format: 8 (Spa:Enum:VideoFormat:BGRx)
info: [pipewire]     Modifier: 0x0
info: [pipewire]     Size: 1366x768
info: [pipewire]     Framerate: 0/1

And 'wireplumber' log tail looks like this:

Code:

Where message 'script/restore-str restore-stream.lua:297:chunk: <WpNode:40:0x55a50fc02720> saving stream props for obs' is printed repeatedly. I've successfully run OBS on gnome with the same pipewire installation. My guess is that the problem may be related to wireplumber not being able to get permissions for capturing the screen. Is it possible to somehow give wireplumber this permission through OBS settings or config file?

I recently had the exact same issue, I solved this by recompiling 3 packages with the USE="screencast" use flag.
I created a file in /etc/portage/package.use/plasma

kde-plasma/kwin screencast
kde-plasma/plasma-workspace screencast
kde-plasma/plasma-desktop screencast

And then update packages with.

emaint --auto sync
emerge --ask --verbose --update --deep --newuse @world
