[webkit-dev] Safari browser on Mac OSX complains "AudioContext.createMediaStreamSource" is undefined !

[Chris Dumez]

Jer or Eric would know more about this but AudioContext.createMediaStreamSource() is behind a MEDIA_STREAM compile-time flag. It appears the mac port does not turn this flag on so Safari does not currently support the Media Stream API.

It's not able to create Audio source node. So I am not able to get the audio sample from microphone in the OnAudioProcess event handler.
