Our proxy server already ‘modifies URLs’. Or more precisely, it acts as a RTSP
server of its own, and therefore provides its own RTSP URLs to ‘front-end’
clients. These differ from the URLs that the proxy server uses to access the
‘back-end’ streams.
I suggest that you begin by familiarizing yourself with the existing “LIVE555
Proxy Server” application, described in
http://www.live555.com/proxyServer/
<http://www.live555.com/proxyServer/>
This appears to already do most of what you want. Note, in particular, that
the proxy server’s ‘back end’ streams (i.e., the streams that it receives) can
be either unicast or multicast. (Note, however, that the proxy server’s
‘front-end’ streams are unicast only, which is not quite what you want; you
noted that you want the front-end streams to be either unicast or multicast.
It would be possible to modify the code to support this, and I could assist you
with this - but some of this assistance would likely be beyond what I can
provide ‘for free’ on this mailing list.)
In any case, I suggest that you first familiarize yourself with the existing
“LIVE555 Proxy Server”.
