Expanded Audio Codec Support

[jodycwilliams]

AAC is pretty sad, as many cameras do not support AAC encoding.

G.722.1
G.711.ulaw
G.711.alaw
MP2L2
G.726

G711 alaw/ulaw is supported on Windows only for the moment. At this point it isn't clear whether and when this will happen for MacOS.

+100. I have mainly Hikvision cameras and it can't capture the audio from these. I've had to resort to the Windoze software rather than use Mac OSX which in my opinion is a far more resilient platform to be running a mission critical application.
