Implement Support for Chapter Extension for VorbisComment

[hirnbloggade]

Over at xiph.org a specification for VorbisComment for Chapter Extensions can be found: https://wiki.xiph.org/Chapter_Extension

Quite a lot of podcasts I listen to already have these comments in their ogg-files (mainly because of auphonic.com) and I'd love to see support for these chapter marks in VLC.

Thanks in advance for considering!

This specification is too stupid for us to implement.

For example, it allows overlapping chapters... Or parts without chapters.
It allows infinite tree of chapters, etc...

[hirnbloggade]

A pity. I'm no programmer who can judge whether a spec is "stupid" or not. I'm just a user who would like to see support for this.

Thanks for thinking about it, though.

Because of the objections, we started a new discussion about the Vorbis Comments chapter extension and reworked it (see this thread: http://lists.xiph.org/pipermail/vorbis- ... 20292.html).

Now the hierarchical chapters support is removed, as you suggested, and it should be straight forward to implement.

Here is an example in the new format:

Code: Select all

CHAPTER001=00:00:00.000 CHAPTER001NAME=Chapter 1 CHAPTER002=00:05:00.000 CHAPTER002NAME=Chapter 2 CHAPTER003=00:07:35.500 CHAPTER002NAME=Chapter 3 ...

Here is the official recommendation: http://wiki.xiph.org/Chapter_Extension

This is especially intersting because also the new Opus format uses these chapters - and Opus is especially intersting for podcasts etc.

Would be great if you can integrate that - if you have any further objections, just let me know!

Note that there is also already a ticket for that in your trac: https://trac.videolan.org/vlc/ticket/6895

Do you have a sample?

[auphonic]

Yes - I attached it to the ticket:
