1. The RTSP protocol establishes the server (the code is C, but look at my client-side code to see how the API is quite straightforward) I modified the code URL

# Copyright (c) 2012 enthusiasticgeek# RTSP demo for Stack Overflowsample: gcc -Wall -I/usr/include/gstreamer-0.10 rtsp.c -o rtsp `pkg-config --libs --cflags gstreamer-0.10 gstreamer-rtsp-0.10` -lglib-2.0 -lgstrtspserver-0.10 -lgstreamer-0.10

Once you have built the binary, simply say it ./rtsp then open another tab in the terminal to test the following pipeline. Test the decoding pipeline. It works very well!
