If I'm reading the chain of message correctly, he is using Flash Player 
to encode his video. Flash Player can encode streams using H.264 (AVC1) 
for video, but doesn't have any iOS compatible audio encoding codecs. 
Therefore he is encoding using Flash Player, then wants to run his 
stream through ffmpeg to re-encode the audio using AAC.

Adobe's failure to include an MP3 or AAC audio encoder in Flash Player 
has had serious negative effects on a lot of developers, including me.
