Hello, I am trying to stream H.263 video whose clock rate is different from 90000. In such a case gst-launch rtspsrc location=<RTSP URL> ! rtph263pdepay ! ffdec_h263 ! ximagesink does not work, with the warning: "pad rtpdec0:sinkrtp returned caps that are not a real subset of its template caps". However, if I go and change the clock rate from 90000 to the range [1, 2147483647] in gst_rtp_h263p_depay_sink_template (gstrtph263pdepay.c), and rebuild and reinstall the gst-plugins-good-0.10.3, the video plays, but not at the correct rate. Where is the correct place in the code to set the clock rate from the SDP? (I can see that gst_rtp_h263p_depay_setcaps() can actually set the caps, and gst_rtspsrc_media_to_caps() can convert the SDP to caps, but how should I link all these to make the thing work, either by changing existing plugin code, or in the gst-launch command line?) Thanks, Deeptendu
