Re: [webrtc-extensions] Should there be an extension to enable voice activity detection for a PeerConnection? (#76)

@fippo There are two distinct questions here.  One is whether whether a particular audio content type (e.g. silence, voice or music) is detected.  The second question is what to do when a given content type is detected.  For example, when silence is detected, the encoder can switch to sending the CN codec until voice is detected again. 

It is worth noting that some codecs have their own algorithms for content type detection.  For example, see:
Opus: https://github.com/xiph/opus/issues/131

Apparently, Opus VAD is better than the VAD algorithm currently supported in libwebrtc.
