           Summary: qtdemux does not detect orientation
    Classification: Platform
           Product: GStreamer
           Version: 1.4.3
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-good
        AssignedTo: gstreamer-bugs at lists.freedesktop.org
        ReportedBy: jpakkane at gmail.com
         QAContact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---


Attached is a video file that has orientation info but gstreamer's qtdemux does
not detect it properly. Running mediainfo on the file says this:

Rotation   : 90°

but if you run gst-play-1.0 with debug level 3, GStreamer says the following:

qtdemux qtdemux.c:7212:qtdemux_inspect_transformation_matrix:<qtdemux0>
Unhandled transformation matrix values

Because of this you can't use the videoflip element with automatic
reorientation.
