 #!/bin/bash

 # This script has a few pre-requisites:
 #
 # 1. The audible-cli must be installed and available in the $PATH.
 #    https://github.com/mkb79/audible-cli
 #    e.g. export PATH=$PATH:/home/$(whoami)/.local/bin
 #
 # 2. The update_chapter_titles.py must also be present in the same 
 #    directory as this file. This also relies on python3 being in the $PATH
 #    https://github.com/mkb79/audible-cli/blob/master/utils/update_chapter_titles.py
 #
 # 3. The $activation_bytes variable must be set with your own Audible account activation
 #    bytes. You can get this using the audible-cli when logged in.
 #
 # 4. asins.txt should be a single-line space-delimited text file containing the ASINS of any
 #    audiobooks you wish to download and configure chapters. These MUST be audiobooks in
 #    your own collection.
 #
 # DESCRIPTION:
 #   This utilises both mkb79's audible-cli and mkb79's update_chapter_titles.py scripts
 #   in order to convert an Audible .AAX file into a DRM-free .m4b file. By default, 
 #   converting just the .AAX file will result in unnamed chapters, so this script
 #   will also grab the raw Audible chapters file and will convert it into a ffmpeg-friendly
 #   metadata format, which is injected in during the conversion step.
 #
 # USAGE:
 #   > ./convert_audible.sh <ACTIVATION_BYTES> <PATH_TO_asins.txt>
 #
 # NOTE:
 #   Some audiobooks advertise a different number of chapters compared to what the
 #   raw chapters JSON file contains. This will be flagged by mkb79's script. It is
 #   generally safe to hit 'y' when this occurs. Most of the time this is due to the
 #   Audible intro/outros being included in the chapter metadata.
 #
 #   Example:
 #     Missmatch between chapter numbers.
 #     Do you want to continue? [y/N]: y
 #
