Well, if you're willing to write code, you can do anything with Mash!

:)

First, consider what you're asking.

If my understanding is correct, RTSP only initiates the stream.  The
stream is usually delivered through some other mechanism.

Mash includes a tool named recorder, which can record RTP streams.  I'm
not sure what limitations it may or may not have.  (Can it record
unicast?  Can it record any content type?)  Paul should be able to
answer these questions.

With RTSP, the streams don't have to be RTP streams though.  If they
are some other delivery mechanism, then we probably don't have any way
to handle it without writing code.

Beyond recording the streams, do you want to record the actual RTSP
exchange?  I would think not, because that would be about as useful as
recording an HTTP exchange.  You're probably only interested in the
content, not the negotiation.  If you are actually interested in the
RTSP exchange, you'd have to write code to do it.

So your first step is to figure out exactly what you want to record...
