Rename chapters when converting

[StefanDorschu]

I would like to rename the chapters instead of using the original file names.

Simple as

Chapter 1 Chapter 2 Chapter 3

Is that possible?

@HabelStefan Unfortunately this is not possible by a simple step or parameter... However, with tone you could write your own little JavaScript tagger, that should do what you like:

1. Create a backup of the original file (before you change something you did not intend)

2 . Create a file reindexChapters.js:

// reindexChapters.js 
function reindexChapters(metadata, parameters) {
  var count = metadata.Chapters.Count;
  var newChapters = [];
  console.log("found " + count + " chapters to reindex");
  for(var i=0;i<count;i++) {
    metadata.Chapters[i].Title = "Chapter " + (i+1);
  }
}

tone.RegisterTagger("reindexChapters");

3. Run the following command to check the results are to your liking

   tone tag "my-audiobook.m4b" --taggers="reindexChapters" --script="reindexChapters.js" --dry-run

4. Run the command without --dry-run to actually perform the changes

   tone tag "my-audiobook.m4b" --taggers="reindexChapters" --script="reindexChapters.js"

Thank you, give it a try !

Works as expected. How can i run it for every file within a directory?

[sandreas]

Should work... just try with --dry-run to check if it works as expected:

tone tag "./my-audiobook-folder" --taggers="reindexChapters" --script="reindexChapters.js" --dry-run

I'm running into an issue which large audiobooks (do know if its the file size (all are bigger than 1GB) or the chapter number).

found 563 chapters to reindex
Error: Object reference not set to an instance of an object.

Any ideas?

Best regards,

Stefan
