I need to write some code that will let me query a m4a file and extract the chapter information out. Including:
- chapter name
- chapter start time
- chapter artwork
I did some quick searching and it seems this is viewed as proprietary information by Apple? I found some discussions, but most were from 2005. Also there have been some similar questions on here, but more for CREATING m4a files with chapters, not querying.
Is this just something I have to DIY, cause there isn't a nice apple API for me to use? Or am I missing something obvious?
Also, ideally I need whatever technique I end up using to work on the iPhone.
