           Summary: v4l2src Missing Some Controls
    Classification: Platform
           Product: GStreamer
           Version: 0.10.28
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-good

     GNOME version: ---


The v4l2src element probes the device to decide which controls to expose via
it's GstColorBalance interface. There are a lot of V4L2 parameters that would
be nice to control via GStreamer that we do not expose. Adding them to the
switch statement in gst_v4l2_fill_lists() in sys/v4l2/v4l2_calls.c would expose
them to GStreamer and make the underlying V4L2 control parameters useful. Good
ones to add include:

V4L2_CID_EXPOSURE_AUTO
V4L2_CID_EXPOSURE_ABSOLUTE
V4L2_CID_EXPOSURE_AUTO_PRIORITY
V4L2_CID_FOCUS_ABSOLUTE
V4L2_CID_FOCUS_RELATIVE
V4L2_CID_FOCUS_AUTO
V4L2_CID_ZOOM_ABSOLUTE
V4L2_CID_ZOOM_RELATIVE
V4L2_CID_ZOOM_CONTINUOUS
