Public bug reported:
I keep getting these errors when trying to set parameters using
libwebcam and uvcdynctrl:
scott@feynman:/home/weather$ uvcdynctrl -d video0 -g 'White Balance
Temperature'=10000
[libwebcam] Unsupported V4L2_CID_EXPOSURE_AUTO control with a non-contiguous
range of choice IDs found
[libwebcam] Invalid or unsupported V4L2 control encountered: ctrl_id =
0x009A0901, name = 'Exposure, Auto'
[libwebcam] Unknown V4L2 private control ID encountered: 0x0A046D03
(V4L2_CID_PRIVATE_BASE + 33844483)
[libwebcam] Unknown V4L2 private control ID encountered: 0x0A046D04
(V4L2_CID_PRIVATE_BASE + 33844484)
ERROR: Unknown control specified.
Before upgrading to Ubuntu 11.10, I never saw any of these issues, so maybe
it's related to a kernel upgrade? I'll try the older kernel and see if that
fixes the problem.
I'm using a Quickcam Pro 9000
