for months we are using OBS Studio with a Green Screen behind me at Red Hat. with Firefox, Zoom, Teams ect… the “virtual OBS Cam” shows up and I can work, so no problem here. But with Chrome, I only can see the external physical Logitech 930e Cam and my internal laptop cam (IBM Thinkpad 480s). I neither can see the Cam in the Chrome settings itself nor in my meet.google.com settings. I have been plowing through a lot of community article without success. The Cam does not appear in google-chrome. Chrome is the Standard Browser at Red Hat, can’t use Firefox for some stateless apps.
As mentioned, with all other apps/browsers I can chose between the three cams, only with Chrome I can’t.
Is this possibly Selinux or fire jail restrictions that need to be adjusted to allow access? I know I have firejail which would not allow this to work. For me firejail would block this it even blocks the simple screen recorder.
I would test renaming your config and cache file .config/google-chrome .cache/google-chrome to.config/google-chrome~ .cache/google-chrome~ with browser closed to back it up and see if a fresh chrome sees the cam as a test? If that failed I would be asking on Googles support.
