Use %title% ID3-Tag as Chapter title.

[sizzleweet]

Hello!

I have a question on chapters.

I have all of my audiobooks in chapterized mp3s.

My mp3s are formatted like this:

• Filename:
  • 01 - Intro.mp3
  • 02 - Chapter 01.mp3
  • etc.
• Tags
  • %track% = 01, %title% = Intro
  • %track% = 02, %title% = Chapter 01
  • etc.

I'm trying to figure out how to use m4b tool within auto-m4b to use the title tag instead of the filename as a chapter title when merging the mp3s.

I saw that in the auto-m4b script it runs this command:

m4b-tool merge "$book" -n -q --audio-bitrate="$bit" --skip-cover --use-filenames-as-chapters --no-chapter-reindexing --audio-codec=libfdk_aac --jobs="$CPUcores" --output-file="$m4bfile" --logfile="$logfile"

I know that the --use-filenames-as-chapters switch is the one that is making it use the filenames, but I want it to use the %track% tag for ordering, and the %title% tag for the chapter name. Is this possible?

I'd also be interested in a way to just strip the first part of the file name when doing this, keeping in mind that some books get to 3 digits for the file number. (I'm looking at you Brandon Sanderson)

What's the best way to go about this and make sure that the setting is preserved even when I update the docker container?

Thanks!
