           Summary: theoradec: Sets video-meta width/height from padded
                    values
    Classification: Platform
           Product: GStreamer
           Version: git
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: blocker
          Priority: Normal
         Component: gst-plugins-good
        AssignedTo: gstreamer-bugs at lists.freedesktop.org
        ReportedBy: nicolas.dufresne at collabora.co.uk
         QAContact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

It looks like theoradec is setting width/height in the GstVideoMeta to padded
width and height, which leads to assertion in VideoFrame when mapping. Width an
and height should be the same as caps in GstVideoMeta, non-padded.

** (gst-launch-1.0:4595): CRITICAL **: gst_video_frame_map_id: assertion
'info->height == meta->height' failed

Program received signal SIGTRAP, Trace/breakpoint trap.
