How to programmatically generate an audio podcast file with chapters and text track?

Question

Hi

Anybody know how to programmatically generate audio podcast files with bookmarks that can be used in iTunes / iPod / iPhone / iPod touch? Specifically text bookmarks (bookmarks with titles) that the listener can skip to a specific point in time in the audio file. Also how to add the text transcription of the podcast's content.

Even better if you have an example Cocoa code or library to write the audio file.

Thanks.

Answer 1

You could generate an XML file for Chapter Tool and then run that on your file.

As for adding a transcription, simply use any meta-data writing library (Quicktime, iTunes via Apple Events) to put the transcription in the lyrics field. I'd recommend the lyrics field over description or summary, because only the lyrics field can be viewed on an iPhone/iPod.
