Ogg index and Skeleton 4.0
...of all active tracks. Thanks to Benjamin for
pointing out the need for this.
* I've removed the requirement in my spec that a keypoint must index
the first keyframe in their page only, and reworded my validity
conditions.
The new spec can be found here:
http://github.com/cpearce/OggIndex/blob/master/Skeleton-4.0-Index-Specification.txt
If anybody thinks anything else should be added to Skeleton 4.0, please
speak up now!
I'm going to create a new wiki page for Skeleton 4.0 to replace the
existing Skeleton 3.0 xiph wiki page, and I'll produce a patch for
ffmpeg2...

Indexing Ogg files for faster seeking
...an
index so that seeking only takes 1 HTTP request.
Using an index of keyframes also makes it easier to seek without visual
artifacts - though of course robust players should be able to do that in
the absence of an index.
You can download the source code for my indexer here:
http://github.com/cpearce/OggIndex
My specification for the index track is stored in that repo, here:

I'd appreciate comments on the spec...
To see how it improves network seeking performance, you can download a
version of Firefox which can take advantage indexes here:

[PATCH] oggz: limit seeking to specified range
...469408 which makes these changes, and it means
that seeks into regions which are buffered are almost instantaneous - which
is a big improvement! I had to change liboggz, so I wonder if you guys would
accept the change in your repository?
My patch to liboggz is below.
All the best,
Chris Pearce (:cpearce)
