Dear All,
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?
