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 Sylwester Nawrocki (3): V4L: Add JPEG compression control class V4L: Add JPEG compression control class documentation gspca: zc3xx: Add V4L2_CID_JPEG_COMPRESSION_QUALITY control support Documentation/DocBook/media/v4l/biblio.xml | 20 +++ Documentation/DocBook/media/v4l/compat.xml | 10 ++ Documentation/DocBook/media/v4l/controls.xml | 161 ++++++++++++++++++++ Documentation/DocBook/media/v4l/v4l2.xml | 9 + .../DocBook/media/v4l/vidioc-g-jpegcomp.xml | 16 ++- drivers/media/video/gspca/zc3xx.c | 45 ++++-- drivers/media/video/v4l2-ctrls.c | 24 +++ include/linux/videodev2.h | 24 +++ 8 files changed, 292 insertions(+), 17 deletions(-) -- 1.7.4.1 -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
