[gst-devel] rtp transmit occur "not-negotiated (-4)" error

[guodecn]

citywolf,
    Because I still don't sovle the problem, I can't help you to test it,I
suggest you modify the client as below:
gst-launch-0.10 -v udpsrc port=40000
caps="application/x-rtp,media=(string)video,clock-rate=(int)90000,encoding-name=(string)H264,payload=(int)96"
! rtph264depay ! ffdec_h264 ! ffmpegcolorspace ! ximagesink.

you can have a test.
