            Bug ID: 783549
           Summary: splitmuxsink: Sink does not recover well after skew
                    reset
    Classification: Platform
           Product: GStreamer
           Version: 1.10.4
                OS: Windows
            Status: NEW
          Severity: normal
          Priority: Normal

     GNOME version: ---

I have a pipeline that gets video from RTSP and saves it using splitmuxsink.  
Pipeline: rtspsrc ! rtph264depay ! h264parse ! splitmuxsink

Occasionally, if the connection to the video source is not very good I start
seeing skew issues.  When this happens I see the warning message "rtp delta too
big, reset skew."  If the jitter buffer decides it is time to reset the skew
the splitmuxsink gets confused and stops splitting files at the correct time
for a while.  
I tracked it down to the call handle_mq_input.  From what I can tell before the
function will call check_completed_gop it first does a check on the running
time with the max running time.  In the case of resetting timestamps caused by
the skew reset, the running time doesn't seem to update until the frame
timestamps catch up to the running time timestamps.  Until then no splits are
made and the video buffer is held on to and grows.  Eventually either the
pipeline shuts down or the timestamps catch up and a large file is written.
