            Bug ID: 766732
           Summary: OpenJPEG Encoder doesn't manage MCT switch for RGB and
                    YUV frames
    Classification: Platform
           Product: GStreamer
           Version: git master
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gst-plugins-bad
          Assignee: gstreamer-bugs at lists.freedesktop.org
          Reporter: boxerab at gmail.com
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

MCT is the J2K transform to convert RGB to YUV.
If the frame is already in YUV format, then this transform does not need to be
performed.  

So, when setting up the encoder, MCT should be zero for YUV colour spaces, and
it should equal 1 for RGB colour spaces.
