Comment (by elkq):

 I apologize if I am not using the correct format to report this issue.
 Please correct me so I might learn the appropriate approach.

 In https://lists.ffmpeg.org/pipermail/ffmpeg-user/2012-May/006601.html
 Dapp Geotz asks for an option to set V4L2_CID_AUTO_WHITE_BALANCE false,
 and an option to set V4L2_CID_FOCUS_AUTO false.

 In addition would very much like to have options to set V4L2_CID_EXPOSURE
 to zero, V4L2_CID_AUTOGAIN to false, V4L2_CID_CHROMA_AGC to false,
 V4L2_CID_HUE_AUTO to false, V4L2_CID_AUTOBRIGHTNESS to false.
