Hi Team,
I have used two pipelines on two different ports.
5001  - for audio
5000 -  for video

audiopipeline = gst_parse_launch("udpsrc port=5001 caps=\"audio/x-raw,
rate = 8000, format=S16LE, channels=2\"  !audioconvert ! audioresample !
autoaudiosink sync=false", &error);


pipeline =  gst_parse_launch("udpsrc port=5000 ! application/x-rtp,
payload=96 ! rtph264depay ! avdec_h264 ! autovideosink sync=false
text-overlay=false", &error);
