Error when trying to decode .aaxc

[dfdy]

When trying to decode .aaxc files I receive the following error:

ERROR: Invalid File: filename.aaxc
Failed to set value 'dc6a163dd68dd1ba25ae3eb71fcd4421' for option 'audible_key': Option not found

Can you provide the output when you run the script with the -l 3 mode enabled? Please also provide the options you were attempting to use.

You probably have an old ffmpeg version, the support for decrypting aaxc files has been added in ffmpeg 4.4. You can check the version with ffmpeg -version
See issue #174

Ah, indeed. I have 4.2.4. Here I was blindly trusting that my repo would have the right version.

EDIT: Can confirm that upgrading ffmpeg to 4.4 worked.
