[FFmpeg-user] Converting Audible AAX

[Paul W]

Hi,

I am trying to use to new  ffmpeg Audible AAX decoder.

The ffmpeg docs mention the  -activation_bytes option, but ffmpeg keeps
throwing an error when I use it.

http://ffmpeg.org/ffmpeg-all.html#Audible-AAX

I have tried ffmpeg 2.7, 2.8.4 and the latest snapshot. None seem to work.

What am I doing wrong?

This is an example of the error I get

$ ffmpeg -activation_bytes xxxxxxxx -i example.aax -vn -c:a copy
example.mp4a
