Hi Wim, As you said, I have edited the TIVidenc1 (mpeg4 encoder element) to include the missing headers. Now, the caps are properly set for the rtpmp4vpay and the udpsink, but I am still unable to see the video via UDP. For RTSP, I am able to see the first few frames only (Actually I see a constant image which corresponds to a frame for some time) and the output ends with a Bus error. I am also attaching a GST_DEBUG=2 output. Thanks in advance. Regards, Neel. Syntax 1: gst-launch-0.10 -v filesrc location=foreman_422_vga._swap.yuv !
