There are plenty of examples to look at. in the RTSP server you can look 
at how rtsp-media-factory-uri.c derives from
rtsp-media-factory.c, for example, and overrides the create_element method.

There is not much other than to understand how subclassing works for 
GObject derived objects, which is explained in the
GObject docs.
