A dirty script to convert Overdrive audiobooks to a single m4b file. Use at your own peril.

brew tap pflouret/tap
brew install overdrive-m4b

or, if you want to use the official ffmpeg without libfdk_aac codec

brew tap pflouret/tap
brew install overdrive-m4b --without-fdk-aac

• https://github.com/chbrown/overdrive Bash script to download overdrive books.
• https://bendodson.com/projects/itunes-artwork-finder Better artwork than the one supplied by overdrive. Put the downloaded 600x600bb.jpg in the same folder as the mp3s.
• User-agent switchers (to get around the OS X Catalina block)

By default, all actions will be run (merge, add metadata tags, add chapters, add cover). Specifying one or more specific action, will only run those.

Author and title will be pulled out of the mp3 tags if available. Override with options.

An <author> - <title>.m4b file will be left in the directory the command is run.
