[asterisk-dev] How about to support multi video tracks of the webrtc sfu?

[Xiemin Chen]

I just made it works with multi video tracks of the echo stream demo by a
few lines of source code change in apps/app_stream_echo.c:

249c249
<                       // continue;
---
>                       continue;
278c278
<               } while (0);
---
>               } while (--n);


Mean while I have a little change in native client code to have two video
tracks in one stream at the same time.

So I think it's not a lot of code change if needs to do this task. I want
to know your ideas, thanks very much.

Sincerely
Xiemin
