Scripting issue with very large files / very many chapters

[sandreas]

The following script runs into an error:

// 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");

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

Original report: sandreas/m4b-tool#216 (comment)

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

Any news on this?

[sandreas]

Still on it. Currently I'm on a nother project taking all of my time... will try to give you an update as soon as it's fixed or I have a workaround.

[StefanDorschu]

Ok. Thank you for all your effort!

@StefanDorschu

tone 0.1.6 is out. Since it is the first release after a long time, this issue may have been fixed with the new jint release. I would love to get feedback, please backup your files.

[StefanDorschu]

Works like a charm! Problem solved!

[sandreas]

Great, closing this issue then :-) Have a nice day.
