parse userdata field of all key frames of MPEG header from rtp video stream using GStreamer

How to parse MPEG stream using GStreamer..? I need to process all userdata field of only key frames(not P-Frames) of MPEG stream.

MPEG stream is coming through rtp protocol. I am able to display the video using GStreamer pipeline, but, my final requirement is to parse userdata field of all key frames and overlay that info into the display video.
