Hi Ross,

Thank you for your answer. I think I have to tell something more about 
the application I have to make. It is not only just a simple proxy 
server, but it has also to deal with unicast streams from network A 
which has to be forwarded as unicast or multicast streams at network B. 
Or multicast streams from network A which has to be forwarded as unicast 
or multicast streams at network B. So I really have to modify the RTSP 
URLs in my proxy server. There is a little more functionallity which 
make it necessary to build my own proxy server, but this is not 
important here.

So my main questions remain:

- In which way can I receive the RTSP messages?
- Which classes do I have to use?
- Can I install a callback method when RTSP messages are received?
- Which test programs can I use to test this locally?

Thanks in advance.
