Warning

The script will fail if the file or directory name contains characters that ffpmeg does not like.

IE - ', ", `, Tab, &, #, * , /, !

I'm working on a function to report on these and possibly replace the offending characters.

Overview

A script to convert directories of mp3 files to a single m4b per directory and add metadata.

Features:

• Parse .json file from audiobookshelf if it exsits in the directory.
• If the ABS json file is not found
  • Pull tag data from the mp3 files if available.
  • Build chapter marker from mp3 file duration and tagging data.
  • If metadata is not available, the final filename will use the enclosing directory's names
• Add "Cover" to final file if cover.jpg is found.
• Combine all mp3s in a directory, sorted by name.
• Convert combined mp3s into m4b file with metata.
• Cleans up temp files created after each book folder is processed.

Note

This does not currently delete the old mp3 files, but I will add the feature in the near future.
