[Freeswitch-users] Video conferencing in freeswitch

[Ken Rice]

How would this work in the real world for the end users especially ones
behind nat where concievably this would allow for splitting the video mixing
off onto another server...

When you get into using things like Polycom Video phones that natively
support h264 and h263 they are looking for the RTP streams as per the SDP...
I can see it being possible that we feed the ip/port combos back to switch
some how but that would be pretty specific to something like sip or h323 and
would leave out any other protocols that can support video but don't operate
using rtp as the media carrier...
