To turn off the auto-focus feature of my webcam, I used the following command:
v4l2-ctl -c focus_auto=0
However, recently, the same command returns the following:
# v4l2-ctl -c focus_auto=0 unknown control 'focus_auto' #
Any ideas?
What does
v4l2-ctl -l
return?
Do you more than one /dev/videoX device?
Thanks, Ed.

I have only one webcam. But I am using a virtual camera via OBS Studio.
