[Live-devel] Live555 RTSP Client never sees RTCP BYE message from Live555 Server

[Matt Schuckmann]

Ok, I'm feeling better now and I've determined that the server is 
attempting to send the RTCP BYE packet in the RTCPInstance destructor 
but by that time all the destinations have been removed from the 
GroupSocket so no data is actually sent (I've confirmed this with 
WireShark).

I had thought that the client could use the receipt of the BYE packet, 
for each stream, from the server as a signal that the session had been 
closed (either the video ended or the server had force-ably closed the 
session (my UI supports this) and the client could clean up and notify 
the user appropriately.
Now I'm not so sure anymore.

I did find a reference on the forums that the server will send the BYE 
packet if the source supports seeking. Why can't it send the BYE packet 
when the session is ending too? Seems like it would be the right thing 
to do.

The shutdown code for the streams is very confusing and I'm not sure how 
to proceed to get things working the way I'd like, can you make any 
suggestions?

Thanks,
Matt S.
