           Summary: [regression] outgoing buffer durations aren't correct
    Classification: Desktop
           Product: GStreamer
           Version: git
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: blocker
          Priority: Normal
         Component: gst-ffmpeg
        AssignedTo: gst...@li...

The buffer timestamp/offset reordering code isn't taking into account the
buffer duration, resulting in outgoing buffers having the proper timestamp...
but not the proper duration.

The following shows the problem (before is before the decoder and after is
after the decoder). Notice the duration of the first buffer coming in and the
first buffer going out.
