Hi all,

As Lorenzo has said, my mediamixer is available on http://sip.fontventa.com/svn/mcu

The software consist in a mixer server with an xml rpc interface and a client library wrapper
ready to use. (xmlrpc-c 1.1 is needed)

The conference creation, participate adding and removing, rtp parameters (send and recevie address)
, encoding paramaters can be controlled with this api.

The video mixing capabilities are the following:

-H263-1996,H263-1998/2000,MPEG4 decoding
-H263-1998,MPEG4 encoding
-Dedicated encoder for each participant, allowing each parameter to have its own encoding
parameter (fps,bandwith, and next week i hope also size).
-Continous presence for four participants (2x2 ), more participants can be added but only shown the first four.


Audio is much simpler and just encoding gsm/pcmu/pcma and audio mixing.

To do:
    -Different composition types
    -Different modes for each participant
    -Mutes
    -VAD and changing position 
    -Forcing participant positioning in composition
    -Define xml protocols calls
    -bug fixes.. :)

It would be great (for Lorenzo and for me) if all the people that were interested in the bounty get a mor detailed 
compromise with the project. It's not for the money, but if you're going to pay some money after all you'll get
more involved in defining all the use cases and functionalities you may need (which would be a great start point
for us).

Greetings
Sergio
