[Live-devel] RTCPInstance questions

[Rawling, Stuart]

Hi all,

I am connecting a client to an RTP server.  I instantiate the groupsocks,
and the RTPSources and the RTCP instance all fine, and the stream comes in
great.  However, I have a couple of questions about the RTCPInstance class.
 
1. Should we be sending RTCP messages when the connection is in a paused
state.  My initial thoughts were no, but then I thought that without the
RTCPInstance running and sending messages, how would a server know the
client has not gone away.

2.  I have debug turned on and I see RTCP messages being received from
myself.  Ie: saw incoming RTCP packet (from address 10.221.224.6, port
7999).  The client is running on 10.221.224.6, and the server is on a
separate box.  It looks to me like the client is receiving its own messages,
but is not chomping them like I would expect.   I think the call to see if
the packets was from ourselves (RTCVP.cpp line 336) is failing for some
reason.  I have no other live555 processes running on the same box, and so
would expect the packet to be ignored.

3.  Occasionally, I will see the sudden the RTCPInstance schedule function
get called in a tight loop.  I am unsure what the cause is, I will be
investigating further, but was curious to see if anyone has seen this one
before.  

Regards,
Stuart
