           Summary: RTSP pipeline freezes when set to a resume after a
                    pause (PLAYING->PAUSED->PLAYING), with Jitterbuffer in
                    Buffering Mode
    Classification: Platform
           Product: GStreamer
           Version: 1.1.3
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: Normal
         Component: gst-plugins-good
        AssignedTo: gstreamer-bugs at lists.freedesktop.org

The RTP timestamp gap induced (nearly equal to the time the server/source has
spent in PAUSED state), currently makes the jitter-buffer completely reset
itself. This leads to freezing of the pipeline, due to the RTP-TS difference
(equal to the time spent in PAUSED state) between the first RTP packet received
after the the source/server has been set to PLAYING and the packet that was
last received during the PAUSED state. This leads to a huge gap (TS
discontinuity) between the first outgoing buffer from the jitter-buffer
post-PAUSED (PLAYING before PAUSED) state and the last buffer that was sent
pre-PAUSED (PLAYING after PAUSED) state. This leads to a long halt at the sink
depending upon the time spent in PAUSED state . i.e long freeze of the
pipeline.
