Hi, I'm running a webradio and I was using aacplusenc as an external encoder to crreate AAC streams.
Since NeroAacEnc is supposed to be superior in quality, and supports ABR streams, I'd like to use that.
Problem is, NeroAacEnc encapsulates the AAC+ data into an MP4 container, which is unsuitable for streaming.

Since I'd use it as external encoder, that reads and writes into pipes, I make NeroAacEnc write to /dev/stdout. I'm struggling to find a solution, how to get the data out of the MP4 container, while streaming live, maybe even encapsulating it in a MPEG2 container, so I can feed a streaming server with that data.

Does anybody know a trick how to do this?
I stumbled upon mpeg4ip which is so old (1997) that the code won't compile, I'm debugging it, so maybe I could use it to extract the AAC stream from the MP4 container on the fly.

Anyway, it would be nice to have an option in NeroAacEnc to inhibit it from putting the AAC stream into the MP4 container and write to STDOUT.

External encoders/decoders work with pipes when used in my radio software.

I f you happen to know anything that might be helpful, please answer!

I think mp4box can export raw aac streams out of MP4.
Just out of curiosity. Can you give more details about your setup?
Is it on windows? How are you feeding files to encode etc?
