Thanks. I solved the problem. There is a script for grabbing the activation code from the registered audible account. That is, you have to have an Audible login account, and books in your library.
The original has a small error, so I forked it from Github, and applied the patch. Well, the patch is already there, but not synched…. and I can see no way of contacting the author?
So I forked my own copy.
This is not my code - and it’s simple Python code, and easy to run from the command line.
and then 1.
ffmpeg -activation_bytes xxxxxxxx -i Volume1.aax -vn -c:a copy -v debug Voume1.mp4
