           Summary: [mpegtsdemux] Confused when receiving segment updates
                    from upstream
    Classification: Platform
           Product: GStreamer
           Version: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-bad
        AssignedTo: gstreamer-bugs at lists.freedesktop.org

     GNOME version: ---


I'm working on implementing DLNA time based fast forward. The idea is to
implement fast forward in dlnasrc by requesting smaller parts of the file to
the HTTP server. Dlnasrc then sends segment updates for each fragment of the
file to play (for example, if rate=2 and we use chunk of 1 second we could have
something like [00:00, 00:01] then [00:02, 00:03] then [00:04; 00:05]).

This works fine with mpegpsdemux but not so much with mpegtsdemux. With 1.4
playback just stops when starting the fast forward.
With this patch
http://cgit.freedesktop.org/~bilboed/gst-plugins-bad/commit/?h=trickmodes&id=bcde22f243a4cc6e053b7d89a435ee021d237214
playback is fine but the reported time is wrong (the position slider in
playback-test is always stuck between the 2 same values).
