            Bug ID: 753869
           Summary: DASH streams using avc1 format fail to display
                    correctly after ABR bitrate switch
    Classification: Platform
           Product: GStreamer
           Version: git master
                OS: Windows
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gst-plugins-bad
          Assignee: gstreamer-bugs at lists.freedesktop.org
          Reporter: bugzilla at ashley-family.net
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

Using the following pipeline:
        gst-launch-1.0 uridecodebin name="uribin"
uri="http://rdmedia.bbc.co.uk/dash/ondemand/bbb/2/client_manifest-avc1.mpd
" \
                caps="video/x-h264, alignment={ au }; audio/mpeg,
mpegversion=4" ! \
                video/x-h264 ! h264parse ! \
        queue ! \
        avdec_h264 ! \
        autovideoconvert ! \
        ximagesink sync=true max-lateness=1000000000 \
                uribin. ! audio/mpeg ! queue ! \
                aacparse ! avdec_aac ! audioconvert ! \
                alsasink max-lateness=1000000000

When the bitrate switch occurs, the display window goes black and the following
errors appear on the console:

** (gst-launch-1.0:7341): CRITICAL **: gst_video_frame_map_id: assertion
'info->width <= meta->width' failed

Trying the same pipeline with an AVC3 stream works correctly:
gst-launch-1.0 uridecodebin name="uribin"
uri="http://rdmedia.bbc.co.uk/dash/ondemand/bbb/2/client_manifest-common_init.mpd"
                caps="video/x-h264, alignment={ au }; audio/mpeg,
mpegversion=4" !                 video/x-h264 ! h264parse ! queue ! avdec_h264
! autovideoconvert ! ximagesink sync=true max-lateness=1000000000              
  uribin. ! audio/mpeg ! queue !                 aacparse ! avdec_aac !
audioconvert !                 alsasink max-lateness=1000000000
