Comment (by reimar):
> matroska_read_seek creates it's index efficiently as far as I can tell
though.
It just reads the index from the file. For real-world cases that is the
most efficient way (though from a pure theory standpoint it is still O(n)
unless the writing application automatically culls the index which has its
own issues and is generally not allowed).
I saw that your files use Ogg skeleton v4, which means that they probably
contain an index, too, so you should be able to implement the same
approach - however it would be a good amount of work I expect.
