Possible audio codecs for mic streaming

[Guest]

We are currently developing a Flash app to capture user's video from webcam and audio from mic and stream to a media server. Flash version 11.6

In our scenario, the best way would be to stream h264+aac in f4v

In NetStream I set h264.

However for Microphone SoundCodec I only have these options: NELLYMOSER|PCMA|PCMU|SPEEX

This would force us to do the transcoding, which is troublesome. Both mp3 and aac would be viable to stream from a client, yet those available in SoundCodec are not really preferable in our case.

If mp3/aac audio encoders are not built-in, then is this possible to create such encoder to make it work with live video rtmp push from the Flash app? Do such (third-party) encoders exist?

I believe that there are many people who wish they could publish microphone audio from a NetStream using the AAC audio codec. This isnt yet supported in the ActionScript AIR, Flash runtimes, so lets add our votes to the Adobe bugbase to get the AAC publish feature implemented.

By doing so, we could stream audio from any AIR supported device to any other AIR supported device with conjunction of StageVideo, hardware acceleration, etc.
