[Asterisk-video] Playing with MCU

[Sergio Garcia Murillo]

Hi Emmanueal,

First, the app_mixer is just for playing and not much,  if you want to do
anything more you should give
mcuWeb a try, it worths it.

The xmlrpc version is 1.1 and the private files I'm using are the one form
the abyss server because on
that release that part was not very well integrated, so I had to do it on my
own.

I'll try to check your seg fault asap.

BR
Sergio
