Vorbis Comment Chapter Extension
More and more people (especially in the german speaking podcasting scene) use the new chapter extension in ogg containers or flac files, see: http://wiki.xiph.org/Chapter_Extension
This enables chapter marks for all fileformats, which use the vorbis comments metadata system (ogg vorbis, flac, speex, the new upcoming opus/celt, etc.).
It would be really cool, if VLC could support this new standard - as it is already possible to show chapters in MP4/M4A files. This is especially interesting for podcaster, audiobooks, lecture recordings, etc.
Furthermore it should be quite easy to implement. If you need any further information or some example files, let me know and I will provide them!
