video not displayed with the use of rtp

[gagankumarnigam]

Hi all,

i have taken demo-send.cpp(from net which is given below) example compiled
and run on one system .It is Running successfully without any error and also
showing display. 

however on client i gave cmd line argument which is running well but not
given any display: It is like that

[arcgis at localhost Desktop]$ gst-launch -v udpsrc port=8999
caps="application/x-rtp,payload=96,encoding-name=H264"  ! rtph264depay !
h264parse ! ffdec_h264 ! autovideosink

and o/p is 

Pipeline is live and does not need PREROLL ...
Setting pipeline to PLAYING ...
New clock: GstSystemClock

but no display..................

Can any one suggest me what is the errrrrrrrrrrrrrrrrrrrrrrrrrrr here??
Server side code is given below
