           Summary: [0.11] Requires width/height/framerate on template
                    caps but shouldn't
    Classification: Platform
           Product: GStreamer
           Version: 0.11.x
        OS/Version: Linux
            Status: NEW
          Severity: blocker
          Priority: Normal
         Component: gst-ffmpeg
        AssignedTo: gstreamer-bugs at lists.freedesktop.org
        ReportedBy: slomo at circular-chaos.org

     GNOME version: ---


The ffmpeg decoders require width/height/framerate on the sink template caps
but really shouldn't for most cases. The container format/parser might not know
these values but ffmpeg is still able to decode the stream.


In 0.10 this worked because there was only an intersection check between the
caps but in 0.11 there is a subset check. In 0.10 it could've happened that
caps without width/height/framerate were accepted although the template caps
required these fields.


NOTE: The same might be true for the audio decoders and possibly and possibly
in the encoders too
