[Asterisk-video] Videomixing in MeetMe

[Lorenzo Miniero]

Hi Klaus,

I've understood the problem, it's here:

> [h263 @ 0xb7eafca0]bitrate tolerance too small for bitrate
> CVM_CLI*> Error opening codec
> CVM_CLI*> Destination 4294967295 added to Session 4
> CVM_CLI*> Error 'Message: Invalid Port for destination'


It's a problem I fixed recently, when I updated ffmpeg I had this issue 
too. You basically need to increase the bit_rate_tolerance value in 
cvm_session.c which was 0, if I remember well. So change it as follows:

	OLD:
	peer->context->bit_rate_tolerance = 0;

	NEW:
	peer->context->bit_rate_tolerance = peer->context->bit_rate/5;

and recompile/reinstall the Confiance VideoMixer. This fixes the problem 
(at least it worked for me).
About QCIF/CIF, I can see from your log that H.263 is negotiated 
(payload type 34), which in Eyebeam's SDP is

	a=fmtp:34 QCIF=1 MaxBR=10485

So QCIF is used, I suppose.

Let me know if it works this way!

Cheers,
Lorenzo
