            Bug ID: 783626
           Summary: openjpegdec doesn't handle grayscale or RGB frames
                    correctly
    Classification: Platform
           Product: GStreamer
           Version: unspecified
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gst-plugins-bad

        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

For grayscale, it tries to access three decoded components instead of one.
For RGB, there are artifacts when using the following pipeline:

 gst-launch-1.0 -v filesrc location=Bretagne1.jp2 ! typefind ! openjpegdec !
imagefreeze ! autovideosink
