Full Version: raw AAC add ADTS headers?

Hello All,

I'm currently on the process to build a simple encoder that appends ADTS headers to a raw AAC stream...

I'm in the first step to understanding how to do such thing... First, how can I tell the start of a aac block from a raw aac file?

I'm not too sure how to begin such task but I'm determined to figure it out and hopefully I can get some wise pointers, url links, whatever it takes! smile.gif


Thanks for your help in advance!

You need to decode the frame to know its length

Thanks again Menno!

So I was able to add ADTS headers and also wrap the AACPlus data on a m4a file type...

My question is: how can I move the moov data to the start of the file? Is there a program that does that? or what are the rule of thumb to move this manually to the start of the file for streaming using home HEX editor?

Thanks!
