I'm trying to broadcast audio over RTP. If I use SoundManager to compress the audio to the MPEG-4 audio format, I can successfully stream and play the audio using the aac-hbr format in my SDP file.
However, if I capture and compress the audio using CoreAudio APIs, the option for MPEG-4 audio is not available. Instead, I get the AAC option. This option seems to generate a different kind of audio packets though, which I can't seem to play successfully.
There doesn't seem to be anything wrong with the base code. When I write the compressed audio data into a Quicktime file, it plays just fine... I just don't know what the difference is between the old MPEG-4 audio and the new AAC format. Can anyone help me?
