I get rtp stream via VLC but not with gstreamer pipeline

Question

I'm trying to get the rtp stream from a DM365 Board.

With VLC there is no problem. Stream can be opened with sdp file. It is a camera view encoded with TI specific h264 encoder (TIVidenc1 codecName=h264enc) and sound. I'm developing an application and i want to use gstreamer. I build a gstreamer pipeline to embedd later video in my app. but I can't open the stream with this pipeline. on ubuntu client pipeline

gst-launch -v gstrtpbin name=rtpbin latency=200 \
udpsrc caps="application/x-rtp,media=(string)video,clock-rate=(int)90000,encoding-name=(string)H264" port=5000 ! rtpbin.recv_rtp_sink_0 \
rtpbin. ! rtph264depay ! decodebin ! xvimagesink \
udpsrc port=5001 ! rtpbin.recv_rtcp_sink_0 \
rtpbin.send_rtcp_src_0 ! udpsink port=5005 host=192.168.231.14 sync=false async=false \
udpsrc caps="application/x-rtp,media=(string)audio,clock-rate=(int)8000,encoding-name=(string)PCMA" port=5002 ! rtpbin.recv_rtp_sink_1 \
rtpbin. ! rtppcmadepay ! decodebin ! audioconvert ! audioresample ! alsasink \
udpsrc port=5003 ! rtpbin.recv_rtcp_sink_1 \
rtpbin.send_rtcp_src_1 ! udpsink port=5007 host=192.168.231.14 sync=false async=false

Sender is DM365 the pipeline is as follow :

SENDER

gst-launch-0.10     gstrtpbin name=rtpbin 

v4l2src always-copy=FALSE input-src=composite ! queue ! 
TIVidResize contiguousInputFrame=FALSE ! 'video/x-raw-yuv,width=608,height=384,format=(fourcc)NV12,bitRate=48100' !

I solved it One need to tell udp caps information from sender side to the updsrc on client side. When you generate a pipeline to send video you get caps information from your sender udp element on the terminal. Just add this to your udpsrc caps="...." and it works.
