You could try to go into the camera's settings and double-check which 
stream(s) are activated to ensure RTSP stream is on, that you're using 
the correct address for that stream, and that there is no authentication 
required. I wouldn't even write a single line of C code until you can 
access it using gst-launch on the command line.
