Based on the last error... mind running nix-shell -p libva-utils --run vainfo?

thanks for the response @eclairevoyant! here's the result:

eclairevoyant commented 3 months ago

probably a config error then, look into https://wiki.archlinux.org/title/Hardware_video_acceleration#Configuring_VA-API etc.

n-sweep commented 3 months ago

@eclairevoyant thanks for the documentation, any insight into what changed from 23.11 to 24.05 that would lead to this? aside from the channel, my config hasn't changed since the package worked.

fpletz commented 3 months ago

But why would obs show no UI if there is no VAAPI support? This is a weird issue.

n-sweep commented 3 months ago

the config steps at https://wiki.archlinux.org/title/Hardware_video_acceleration#Configuring_VA-API unfortunately didn't affect the behavior

But why would obs show no UI if there is no VAAPI support? This is a weird issue.

I also cannot kill the obs processes once started, they can only be stopped by rebooting
