            Bug ID: 752413
           Summary: dashdemux: add support for parsing UTCTiming elements
    Classification: Platform
           Product: GStreamer
           Version: git master
                OS: All
            Status: NEW
          Severity: enhancement
          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: ---

Unless the DASH client can compensate for the difference between its clock and
the clock used by the server, the client might request fragments that either
not yet on the server or fragments that have already been expired from the
server. This is an issue because these requests can propagate all the way back
to the origin

ISO/IEC 23009-1:2014/PDAM 1 defines a new UTCTiming element to allow a DASH
client to track the clock used by the server generating the DASH stream.

This bug ticket is a request to implement this feature in dashdemux. Given that
this is a DASH specific feature, I think it belongs in dashdemux rather than
adaptivedemux.
