Recording AAC in ADTS transport instead of MP4

Rob_W · August 30, 2012, 9:24pm

I am streaming AAC-encoded audio into Wowza, which is wrapping it in a MP4 container before re-streaming/recording.

I’m fine with onward live streaming in MP4 format but I would like to record to disk in a plain ADTS wrapper. Is this possible to achieve?

No, your options are flv or mp4 files.

Ok, I thought so - thanks.

Is it possible to extract the AAC from the MP4 container without re-encoding? What would the ffmpeg command be for this?

Hi

I believe that you can do this with ffmpeg and the command is :

ffmpeg -i [file name] -acodec copy outputfile.aac
