Ross,

Ok...that makes sense. Any idea how Proxy Server would handle the following
url?

rtsp://<ip>:<port>/axis-media/media.amp?resolution=480x270&fps=3&compression=40&videokeyframeinterval=18

>From debug I can see ProxyServer handles the new subsession like this:

ProxyServerMediaSession["rtsp://99.58.86.198:11031/axis-media/media.amp/"]

Proxy Server DESCRIBE on registered stream returns sdp:

a=control:rtsp://<ip>:<port>/axis-media/media.amp?resolution=480x270&fps=3&compression=40&videokeyframeinterval=18
a=control:rtsp://<ip>:<port>/axis-media/media.amp/trackID=1?resolution=480x270&fps=3&compression=40&videokeyframeinterval=18

>From the client side I have tried DESCRIBE against the Proxy Server using
all possible suffix's with no success.

Seems I might have to handle this differently. Either way I am much further
along with understanding how to implement this feature.


Thanks,

Bob
