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.

So you are actually getting the video to come out though? I am not getting any outbound video RTP traffic at all. What settings do you have?
If I get a chance this weekend I will take a look at the implementation and see what I can see. The mosaic thing should be pretty easy actually (really, just a scaling of each incoming stream and tiling them), but that won't work well for anything bigger than a 2x2 matrix, considering the bandwidth limitations of most users.

That's one of the things that's been on our (1control, I have nothing to do with Digium) wishlist/"to do" list that just hasn't gotten done yet.
Currently, video in meetme is not supported. What we experience is the audio will conference with the other audio streams but the video just freezes. I was hoping to look into someday but I'm swamped with 1000 other things of higher priority. I have been thinking though, of some ways it could be supported, starting with the simplest and easiest:
1. First, if only 2 of the phones in the conference are video phones, allow them to exchange their video with each other, while having all of the audio streams conferenced as usual.
2a. The next step could be having each videophone "rotate" which stream it was showing for a few seconds (20 seconds maybe?). i.e. you could have 3 video calls mixed with several audio-only calls. Initially video call #1 would show #2's image, #2 would show #3's image, #3 would show #1's image for a few seconds, then rotate them by 1. Of course you don't need to show your own! :) Actually, ours has a picture-in-picutre in the corner so you can see yourself all the time anyway.
2b. The other option instead of time-rotating the images would be to try to show the image of whoever was talking. That kind of sounds like a pain to me, but maybe it's doable.
3. The really fancy thing would be to have Asterisk decode all of the video frames and create a 2x2 or 2x3 or 3x3 etc. mosaic, re-encode them and send them to each client. That REALLY sounds like a pain to me, but again, maybe it's doable.
Right now I'd be pretty happy with 2a though.

Hello All:
Has anyone configured a meetme conference to use video?>I have successfully used video phones to talk through *, but I cannot seem >to get video when those phones dial into a meetme conference. > >Is there something else that I need to be doing other than set the "v" flagon my extension for the meetme app?
