           Summary: gstrtpbin fails to associate streams together for
                    lipsync
           Product: GStreamer
           Version: HEAD CVS
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-bad
        AssignedTo: gstreamer-bugs at lists.sourceforge.net

     GNOME version: Unspecified
   GNOME milestone: Unspecified


GstRtpBin will not associate streams together for lip-sync unless they have the
clock-rate set. The only way their clock-rate can be set it from the pad that
comes out of the ssrc demux, but this pad never has caps on it (the caps are
just set on the buffer later in the pt demuxer!). So the association never
happens.

I'm attaching a patch that uses the ptdemuxer's payload-type-changed signal to
signal what is the last pt that was received on that stream, this PT is then
used to request the pt-map and then get the clock-rate.
