I am facing some other problem in RTP Streaming... I am sending the rtp data over the UDP and playing it on the other end. I am recording the data from v4l2src @ 10 fps  and  voice data from alsasrc to send it across. The transmission starts well as well as i can see the video on the other end. Now in between i starts to take the data from a file. I decode the data and encode again to send it using the same rtpbin and udpsink. Enc, Pay gstrtpbin and udpsink are the element kept common...means i will use these elements in both the cases. the packets goes well and on the other end i can see the AV fine in both the cases.... Now when i again switch back to v4l2src the packets on the receiver end come but the decoder (ffdec_mpeg4) gives error.......and there is no updates on display........ The file i am using is @25fps...... also when i increase the FPS of v4l2src the whole system works well.....@20 fps..... Please let me know if i am missing something or i am doing something wrong way.... Also i tried using different enc and pay elements in both the case..but i i unlink and link to gstrtpbin, there is no data at all..even in the first switch to file transfer.............. :( Please help...i have tried every possible thing to fix this issue....but i am stuck with the same for last couple of days now..... Any input will be appreciated from bottum of heart.......

Run the sender pipeline with -v, then copy the caps on the RTP udpsink to the receiver udpsrc caps (and yes, they are huge and they are needed). Wim<o:p></o:p> <div> <div> > > Any suggestion?
