Hi All,

As the media mixer is not available at this point of time and i have  
50+ multiparty joining the conference call.

Can we dynamically add and delete streams at run time? I am sure there will  
be some delay associated with it, but theoretically is it possible?

The other problem with 50+ participants is we cannot open so many connects,  
my browser will die, firstly it cannot handle so many DOM objects and the  
bandwidth required will be very high (i guess 2 extra connections  
(peerConnection: video, audio) for each new participant.

Please correct me if my assumptions are wrong. Also suggest me kind advise.  
Thanks.

Regards  
-Milind

Hi,

as Licode is designed each participant sends it media only one time, it has  
a peerconnection for publish its stream and a peerconnection for each  
subscribe stream. So for each new participant in the room a client only  
adds one peerconnection. So, 50 participants implies 50 peerconnection in  
each client. There are much less than in a p2p scenario without Licode, but  
probably there are so many for a browser. However you can try it and tell  
as the results.

About dynamic streams adding and deletion, it is possible publishing and  
subscribing them.
