I got one step further. I was able to set the Power Line frequency without a problem. I could read the current values of 'White Balance Temperature' and Exposure (Absolute) but setting them to the windows value failed: ./uvcdynctrl -s 'White Balance Temperature' 7322 [libwebcam] Unknown V4L2 control ID encountered: 10094851 ERROR: Unable to set new control value: A Video4Linux2 API call returned an unexpected error 5. (Code: 12) ./uvcdynctrl -s 'Exposure (Absolute)' 160 [libwebcam] Unknown V4L2 control ID encountered: 10094851 ERROR: Unable to set new control value: A Video4Linux2 API call returned an unexpected error 5. (Code: 12) Getting (and setting) the value of Exposure, Auto Priority failed as well. ./uvcdynctrl -g 'Exposure, Auto Priority' [libwebcam] Unknown V4L2 control ID encountered: 10094851 ERROR: Unknown control specified.
