           Summary: v4l2src only exposes a limmited set of properties
           Product: GStreamer
           Version: HEAD CVS
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-good
        AssignedTo: gstreamer-bugs at lists.sourceforge.net
        ReportedBy: ensonic at sonicpulse.de

     GNOME version: Unspecified
   GNOME milestone: Unspecified


v4l2src currently exposes mandatory properties as gobject properties and uses
three interfaces for optional things:
  GstTuner
  GstColorBalance
  GstVideoOrientation
It also implements GstPropertyProbe (for probing device-names?)

The v4l2 standard defines many custom controls that would be useful to be
controlled from applications. drivers can also register own custom controls.

How to get the to the apps?
1.) Expose the fd. Ugly.
2.) For known properties define more interfaces. E.g. a PhotoCaptureInterface
for AutoWhiteBalance,AutoExposure,... . There are new control commin all the
time, so it needs constant maintenance.
3.) Create a control class on-the-fly and use it via ChildProxy
4.) <your idea here>
