Additional feature python scripts for post extracted libby .mp3s

[hoodedrobin1]

First I want to state that I probably didn't read directions well enough and there is a good chance I didn't know what the heck I was doing - so this might not be useful for you. This is my first time writing python code for a pre-existing project so its a little rough.

I was not able to keep chapters when converting to .m4b so I wrote the following. I did use chatgpt for a couple parts as I didn't know all of the ffmpeg settings and also I wanted messages if there were errors while running the scripts. (they are attached in a zip file, I don't know how to add ,py scripts to a post)

The first script I created was to add all of the .mp3 files in a directory to a .m4b file (I was only able to do 1 mp3 at a time and not convert into 1 .m4b):
convertToM4bFULL.py

I wanted to be able to count the number of chapters a .m4b file had - which seem to be lost when converting the .mp3 to .m4b (see above):
countchapters.py

I created a python script to convert the .json file to a chapters.txt file for ffmpeg to add chapters to a .m4b:
json_to_chapters_txt.py

lastly I wanted to add the chapters from chapters.txt to the .m4b:
chapterize.py

here are the python scripts: extra_libby_scripts.zip
