  GStreamer | gstreamer (core) | Ver: HEAD CVS
           Summary: gst_segment_set_newsegment does not accumulate correctly
           Product: GStreamer
           Version: HEAD CVS
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: Normal
         Component: gstreamer (core)
        AssignedTo: gstreamer-bugs at lists.sourceforge.net
        ReportedBy: julien at moutte.net
         QAContact: gstreamer-bugs at lists.sourceforge.net
     GNOME version: Unspecified
   GNOME milestone: Unspecified


When receiving a sequence of segments like this :

update 0 rate -1.0 start 0 stop Y last_stop Y (typical reverse playback)

and then

update 1 rate -1.0 start X stop Y last_stop X (closing reverse playback
segment, no flush)

update 0 rate 1.0 start X stop Z (duration) last_stop X (starting forward
playback again)

The segment accumulated duration is wrong. Indeed the closing/update of the
reverse playback segment is accumulating X when it should not accumulate
anything until the non update segment arrives and then accumulate Y - X which
is the duration we have played in reverse playback.
