           Summary: qtdemux causes soup to request seeks past the end of
                    the range
    Classification: Desktop
           Product: GStreamer
           Version: git
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-good
        AssignedTo: gstreamer-bugs at lists.sourceforge.net
        ReportedBy: sjoerd at luon.net

Running:

totem
'http://trailers.apple.com/movies/independent/thegirlwhokickedthehornetsnest/girlwhokickedthehornetsnest-tlr1_480p.mov'

Results in souphttpsrc throwing a seek error: ``Server does not support
seeking.''

This turns out to be caused by a seek past the end of the content (as reported
by the Content-Length header in http headers). Looking more closely it seems
the simplified pipeline looks like this:

souphttpsrc ! queue2 ! qtdemux

qtdemux loops over all state headers untill gst_pad_pull_range returns
UNEXPECTED, queue2 seems to transform get_range calls into seeks on its source
pipeline. Which causes qtdemux to trigger a seek to paste the end of the file,
causing it all to go horribly wrong :/
