I'm trying to figure out how to create mp4 audio files (aac codec) that have chapter information that will work in iTunes, or on an iPod (for podcasting purposes). I've only found one linux program that claims to be able to add chapter info to an mp4 file: MP4Box, part of the GPAC package.

I know how to make the mp4 files (with faac, or MP4Box), without a problem, and they work fine on iTunes. However, I can't figure out how to get workable chapters. According to the GPAC website, there are four valid chapter file formats. I've tried them all, but they didn't work.

The chapters showed up properly when I type MP4Box -info File.mp4, but iTunes doesn't seem to support chapters like these. They didn't work in Totem or VLC either.

I also tried an xml format that I found on a tutorial specifically about making chapters for podcasting. But this tutorial was supposed to be for someone using Quicktime on a Mac. It didn't work.

Does anyone have any idea how I can add chapters to an mp4 file in Linux that will work in iTunes?
