           Summary: [ffmpegcolorspace] AYUV->RGB is broken
           Product: GStreamer
           Version: HEAD CVS
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins
        AssignedTo: gstreamer-bugs at lists.sourceforge.net
        ReportedBy: algernon at bonehunter.rulez.org

Test case:

gst-launch videotestsrc ! alpha ! ffmpegcolorspace ! ximagesink

Result:

Observe that the picture is half the expected width (the rest being black), and
the colors are rather weird.

Expected result:

The normal videotestsrc result.

Workaround:

Converting to another YUV format, and then to RGB seems to fix the problem.

Eg, this works:

gst-launch videotestsrc ! alpha ! ffmpegcolorspace !
video/x-raw-yuv,format=(fourcc)AYUV ! ffmpegcolorspace ! ximagesink
