[PATCH/RFC v3 0/3] JPEG codecs control class



Hello,

this patch set adds new control class - V4L2_CID_JPEG_CLASS initially
containing four controls. It also adds V4L2_CID_JPEG_COMPRESSION_QUALITY
control to zc3xx gspca sub-device. The gspca patch has been tested with
v4l2ucp and v4l2-ctl.

The initial RFC can be found at
http://www.mail-archive.com/linux-media@xxxxxxxxxxxxxxx/msg39012.html

Changes since v2:
 - improved gspca/z3cxx patch according Jef's comments;
 - removed patch adding jpeg quality control to gspca/sonixj;
 - patches 1/3, 2/3 are unchanged;

Changes since v1:
 - removed trailing 'S' from V4L2_CID_JPEG_ACTIVE_MARKERS;
 - removed V4L2_JPEG_ACTIVE_MARKER_DAC and V4L2_JPEG_ACTIVE_MARKER_DNL
   definitions as these are normally controlled by higher level compression
   attributes and shouldn't be allowed to be discarded independently;


Thanks,
Sylwester
