[Asterisk-Users] Re: MeetMe Video option

[John Todd]

Tim -
   I'm actually quite fond of the 2b solution in the video conference 
tools I've used (notably, Polycomm) where the video switches or 
camera pans depending on audio energy.  This could work quite well 
with the existing features of "m" and "t".

   A combination of blending an audio-energy and 2x2 matrix would also 
be pretty slick, where maybe some callers would be "nailed-up" and 
never would leave the matrix, but the remaining panels would 
fluctuate based on last audio energy input.  It would lead to 
interesting shouting matches in circumstances outside of "corporate" 
use of videophone technology.  :-)

   It's a shame that * doesn't have Solaris as a well-supported (at 
all? anyone?) platform; there are the Sparc routines for fast video 
transforms built into the Sparc processor chipset that could do 
really cool and fast stuff for videoconferencing routines.

   So, I'm waiting for the iChat video client software to be supported 
via *; then I'll actually invest in the slick Apple firewire camera.
