  GStreamer | don't know | Ver: git
           Summary: rtsp/rtp streaming fails when skipping explicit PAUSED
                    state change
           Product: GStreamer
           Version: git
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: don't know
        AssignedTo: gstreamer-bugs at lists.sourceforge.net
        ReportedBy: mail at renestadler.de
         QAContact: gstreamer-bugs at lists.sourceforge.net
     GNOME version: Unspecified
   GNOME milestone: Unspecified


Attaching a pygst test program. Run it without arguments to get this:
0:00:01.166385865 19608      0x1058c40 WARN               rtpsource
rtpsource.c:925:calculate_jitter: cannot get current time
0:00:01.371305072 19608      0x1058c40 WARN               rtpsource
rtpsource.c:925:calculate_jitter: cannot get current time
0:00:01.591286913 19608      0x1058c40 WARN               rtpsource
rtpsource.c:925:calculate_jitter: cannot get current time
[...]

and no playback. If you comment in the intermediate state change to PAUSED, it
works:
    ## p.set_state (gst.STATE_PAUSED)
    p.set_state (gst.STATE_PLAYING)
-->
    p.set_state (gst.STATE_PAUSED)
    p.set_state (gst.STATE_PLAYING)

Doesn't make much sense at all; I debugged it a little and it seems that the
pipeline clock isn't distributed correctly for some reason...
