In case someone is wondering why their decklink device doesn't work (green screen) with the current obs-studio 26.1.0 from the repo, there is some bug that is now fixed in 26.1.1: https://github.com/obsproject/obs-studio/releases/tag/26.1.1
For some reason this isn't updated for days in the repo. Building obs from PKGBUILD with adapted version string and md5sums worked for me.

I finally had time to investigate the issue. It looks like that as of 11.5, the
DesktopVideoHelper.service
has to be running for the capture card to work properly.
