Using the logs to detect a problem with webcam on OBS-Studio

[Paul Smith]

Dear All,

After having upgraded from F33 to F34, my webcam was still detected by
OBS-Studio. However, it did not display any image -- only a black
rectangle.

It took me a lot of time to find out the cause: The resolution of my
webcam on OBS-Studio was configured as

"Leave unchanged"

and it should be

"1280x720".

So my question is: Could this problem have been spotted in some logs?

Thanks in advance,

Paul
