udp caps fail

[metind]

Dear all,

I am using this pipeline to send audio video (audio 5000 and video 5002);
gst-launch-0.10 -v audiotestsrc ! audioconvert ! ffenc_aac ! queue !
rtpmp4apay ! udpsink host=127.0.0.1 port=5000 videotestsrc ! ffenc_mpeg4 !
queue ! rtpmp4vpay send-config=true ! udpsink host=127.0.0.1 port=5002

and the debug text is;

New clock: GstSystemClock


And then to get only video part, i am using this pipeline;

GST_DEBUG=*:2 gst-launch-0.10  udpsrc port=5002 caps="application/x-rtp,
media=(string)video, clock-rate=(int)90000, encoding-name=(string)MP4V-ES,
profile-level-id=(string)1,
config=(string)000001b001000001b58913000001000000012000c48d8800f50a041e1463000001b24c61766335332e33352e30,
payload=(int)96, ssrc=(uint)475401716, clock-base=(uint)2048383010,
seqnum-base=(uint)16002" ! rtpmp4vdepay ! ffdec_mpeg4 ! xvimagesink

but it gives error as;

I think i used correct caps for video but couldnt play it. I need your
advice to solve this problem.

Best regards,
