           Summary: rtpsource on receiver side can't get clock-rate for
                    h264, h263 or mpeg4
           Product: GStreamer
           Version: HEAD CVS
          Platform: Other
        OS/Version: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-good
        AssignedTo: gstreamer-bugs at lists.sourceforge.net
        ReportedBy: le.businessman at gmail.com
         QAContact: gstreamer-bugs at lists.sourceforge.net
     GNOME version: 2.21/2.22
   GNOME milestone: Unspecified


Please describe the problem:
normally, it is not necessary to specify payload type on the receiver side's
udpsrc caps for an rtp session. However, for h264, h263 and mpeg4 video
streams, if you don't specify payload-type, you get the following warning:

rtpsource rtpsource.c:865:calculate_jitter: cannot get clock-rate for pt 96


Steps to reproduce:
Setup a stream such as the one described here: 
http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-bad-plugins/html/gst-plugins-bad-plugins-gstrtpbin.html
using either h264, h263 or mpeg4, and set GST_DEBUG level to two

Actual results:
rtpsource rtpsource.c:865:calculate_jitter: cannot get clock-rate for pt 96

Expected results:
The payload type would not need to be specified and we would not get this
warning.

Does this happen every time?
Yes.

Other information:
I have not observed this behaviour for any audio codec/payloader/depayloader
combinations.
