>> I was told that it's not support by asterisk to have multi video tracks of one client in the following post. How about if I want to achieve this functionality? Is there any technical limitation?<br>
<br>
I think Josh's response on the community forums implied that there<br>
probably *are* going to be technical limitations. I don't think<br>
anybody's tried to prototype a single client with multiple resolutions<br>
of the same stream from the same endpoint at this point.<br>
<br>
So I guess maybe trying to build a browser app prototype that can<br>
produce that scenario first would be a good start. Then you'll need<br>
to see how that's represented in SDP, to figure out how that lines up<br>
with Asterisk's multi-stream capabilities and make sure that it tries<br>
to do the right thing from its side.<br>
<br>
As Josh mentioned, there's gonna be a bit of work to make things happy<br>
inside of Asterisk. It sounds like a really fun project though, and<br>
if you manage to get somewhere on it I'd love to hear about your<br>
progress.<br>
<br>
Good luck and best wishes!<br>
