destination= address in transport header

[Sudipta]

Hi,

I am using Darwin Streaming Server to play some video clips
with my client application issuing RTSP commands.
In my application, I need to specify different IP
address as a recipient of Audi/Video RTP streams
that the IP address where RTSP commands/requests are
sent. I read in the RTSP RFC 2326bis and found that
it can be specified in the Transport hdr field of
SETUP request. But it is not working. Is this
feature supported in Darwin at all?
If so how do I make it work?

Thanks
