Audio & Video Codec Change

Hi Team,

We are developing a conferencing solution on top of licode.

We want a better quality audio so we want to change the codec of licode to PCMU(default) to Opus. and for the video, we are planning to go for VP9 rather than VP8.

What is the reason we selected PCMU as default?

Will these changes cause any problems? Do these configurations have any dependencies with other features like recordings?

Thanks & Regards
Nibin Thomas
