ID3: CHAP frame support

[GoogleCodeExporter]

Hi,

I'm trying to implement Chapter support in my application, as per:
http://www.id3.org/id3v2-chapters-1.0

However, it's unclear how to do this or even if it is supported.

Thanks!

No, Mutagen doesn't (yet) support CHAP. The tag as a whole is a really horrible
design, since it keeps raw byte offsets into the file and allows arbitrary deep 
nesting.

Audio books and full podcasts of magazines (e.g. The Economist) make use of M4A
format audio files with internal chapter marks.  When there are ~100 chapters 
(every
article in a 100page magazine) being able to edit the chapter tags becomes quite
relevant.  Anyway, this is all just to justify my vote.  With some pointers, 
I'd be
able to commit a few days to implementing this.

This is specifically about CHAP support, which has nothing to do with MP4/M4A. 
That
being said, mutagen.mp4 is only 460 lines of code, so I don't know what kind of
pointers you'd next.

(p.s. There's no votes. This isn't a democracy.)

Just wanted to ask again for MP3 chapters support.
In the german podcasting scene this format is already used by many people and 
displayed by podcatchers on Androind (the open-source AntennaPod, 
https://github.com/danieloeh/AntennaPod) and iOS (e.g. the popular instacast 
http://vemedio.com/products/instacast).

It really makes sense for podcasts, audiobooks etc. - most of the time you have 
to provide an MP3 format (because all old cheap players support it) and with 
the ID3 chapter extension it's possible to add chapters too, which is 
especially useful for long podcasts.

We (auphonic.com) support these chapters too - if you need some code or audio 
examples, just let me know, I would be happy to send them to you!
We will maybe also build a simple tool, but I think these chapters should go 
into a major library, so that as many people as possible can use it!

Have a nice day,
LG
Georg

FYI: this is now also integrated in the python eyeD3 tagging library:
