[Asterisk-video] CPU Utilization of H.264 Conference with MCU

[Sergio Garcia Murillo]

Hi Kiran,

The CPU utilization is something that we cannot reduce, it is bound to 
the encoding process, which is something expensive if using h264.

You can do one of the following things, reduce the video quality (either 
going to QCIF, or H263 or reducing fps) or increase the CPU power of 
your server. I have made test with up to 8 participants using HD(720P) 
video at 30fps.

Also, the mcu allows you have more than one mixer configured to be able 
to use more than one server at a time.

Best regards
Sergio
