Hi, This patchset is a follow up of an RFC which can be found here: http://www.mail-archive.com/linux-media@xxxxxxxxxxxxxxx/msg39012.html It creates a new JPEG control class with a tiny amount of four controls in it. It also adds V4L2_CID_JPEG_COMPRESSION_QUALITY control to two gspca sub-devices: sonixj and zc3xx, as these where drivers I had the hardware handy for. The gspca patches have been tested with v4l2ucp and v4l2-ctl. The compression quality control together with other controls on a panel is quite convenient. It allows to improve image quality instantly, without a need for using additional application that handles VIDIOC_S/G_JPEGCOMP.
