Camera model
UTHAI DM20(?) cheap cam from aliexpress (1.91€ 71% OFF|UTHAI D01 Stick freies 1080P 720P 480P netzwerk teaching USB kamera live computer kamera| | - AliExpress)
What is the problem?
I get only noise. The cam work on PC.
What did you already try to solve it?
Changed resolution and frame rate. Added the -y param.
Seems like the pi detect the cam:

Additional information about your setup
Hi,
I'm trying to connect a webcam to my OctoPrint, and I get noise (regardless of the resolution I choose).
The cam work perfect with a PC.
I tried to add the -y param, but then the daemon won't start.
There's no log for the webcam daemon in /var/log.
I found in that folder a file named daemon.log with the following:
