So why am I getting this error message in webcamd.log?

Not sure how to help with this, there is a thread about this particular camera here:
https://community.octoprint.org/t/octoprint-logitech-c270/5309/4

[cp2004]

The reason you have the error is because the camera is in this list:

OctoPi/src/modules/octopi/filesystem/home/root/bin/webcamd

Line 18 in f5ed20c

brokenfps_usb_devices=("046d:082b" "1908:2310" "0458:708c" "0458:6006" "1e4e:0102" "0471:0311" "038f:6001" "046d:0804" "046d:0825" "046d:0994" "0ac8:3450")

You can try editing that file (/root/bin/webcamd, requires sudo) and removing the ID, and seeing what happens. It might break something, but that's an experiment you can perform 🙂

removing the ID has helped with me.
My video was delayed over 30 seconds in places and hung constantly.
But what is the exact reason why the camera id is listed in this list.
I didn't find any hint in the list of cameras working with Octopi.
