@anon89812132 — I had mentioned this in the other thread.
So, below is the output for the command
[werunom@thinkpad ~]$ v4l2-ctl --list-devices
Droidcam (platform:v4l2loopback_dc-000):
/dev/video0
Integrated Camera: Integrated C (usb-0000:00:14.0-8):
/dev/video1
/dev/video2
(As a temporary workaround, I installed droidcam. that is why you see that also in the output.)
Anyways, looks like this problem is not related to an isolated problem. Given that 3 people have it, looks like the recent update broke something
