  GStreamer | gst-plugins-bad | Ver: HEAD CVS
           Summary: [qtmux] Dirac stream has wrong duration and initial
                    timestamps
           Product: GStreamer
           Version: HEAD CVS
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-bad
        AssignedTo: gstreamer-bugs at lists.sourceforge.net
        ReportedBy: manauw at skynet.be
         QAContact: gstreamer-bugs at lists.sourceforge.net
     GNOME version: Unspecified
   GNOME milestone: Unspecified


Assumption:
schroenc's initial buffer can have dts (= OFFSET_END) < 0
[seems to be possible given the present code path that exists for this
contingency, and so confirmed by test]

In the above case, when processing first buffers, scaled_dts is calculated < 0,
and then also scaled_duration < 0 (or "equivalently" >> 0).
This is passed to lower layers, leading to a first "delta" >> 0, and therefore
wrong duration overall (and timestamp).
