Hi Ross,
> The "ProxyServerMediaSession" class was intended to be a self-contained, > fully-featured class that could be used 'as is' to build RTSP proxy > servers. For now at least, it is not intended to be customizable.

At least until this moment it seems to work... :-D Is this the correct way to do it? There's another better, more direct way to be notified so i don't need to create the two new child classes? However, as you noted, we don't want the 'back-end' server to be streaming > data when it's not needed. Our implementation accomplishes this not by > closing the connection when the last client leaves, but instead by > automatically sending a RTSP "PAUSE" command to stop the stream. (Later, > if a new client arrives, the proxy will automatically resume the streaming > by sending another RTSP "PLAY" command.) > This are REALLY great news! :-D I was thinking about to close the connection checking the ProxyServerMediaSession referenceCount, but if this is done internally by the proxy and in a better way (pause the stream instead of close the connection) i think is a great improve :-) Thanks! :-D P.D.: As a side note, to put just a single line on the Doxygen explain what each method is intended for would be a huge imprevent... ;-) -- Jesús Leganés Combarro <jesus...@vaelsys.com> Software developer at Vaelsys <http://www.vaelsys.com>
