I am trying to

1. read a RTSP stream from an IP camera
2. take the audio signal
3. process it and stream it with mp3cast~.

Number 3 is done, but I just cannot figure out how to read a RTSP stream. Even worse: It should be able to run on Windows 7!

pdgst seemed to be a possiblity, but I couldn't compile it yet.

Can anybody point me to a direction how to go on with this problem?
