Spectator View: failed to record my voice #71

i used opencv and a Logitech webcam to capture the video, i can record the video, but i can not record my voice through the webcam. I checked the ENCODE_AUDIO is TRUE. I do not known where is wrong.

Spectator view does not currently support recording ambient audio. ENCODE_AUDIO will only record audio from Unity. For now, you can record your ambient audio with an external program and overlay in post-production.

I am not sure if OpenCV directly supports getting audio frames from webcams. DeckLink and Elgato do retrieve audio frames over HDMI, but that data is not plumbed through to the video output.

Changing this to a feature request.
