            Bug ID: 748893
           Summary: RTSP clock jumps after a lunch break
    Classification: Platform
           Product: GStreamer
           Version: git master
                OS: Mac OS
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: don't know
          Assignee: gstreamer-bugs at lists.freedesktop.org
          Reporter: vivia at ahiru.eu
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

Only tried on OSX so far.

Sender pipeline: ./test-launch "videotestsrc is-live=true pattern-18 !
timeoverlay font-desc=\",48\" !
video/x-raw,width=1280,height=720,framerate=30/1 ! x264enc ! h264parse !
rtph264pay name=pay0 pt=96"
Receiver pipeline: Just play the above using gst-play.

Steps to reproduce: Start the above, go to lunch or otherwise leave the Macbook
intact for maybe half an hour, come back, wake up the Macbook.

Symptom: Both the bouncy ball from videotestsrc and the clock from timeoverlay
will be jumping forward - they play back for maybe about a second, then jump
forward for a couple of seconds, etc etc.

Lame screen capture (from phone) available at

Will test on Linux and report back.
