Well, there are different things. On the muxer part when a chapters are
added, they should be mentioned in the Meta Seek. And there really should
always be a meta seek (at least without the clusters).
Then on the playback there should be a simple option like "fast load" that
will only load the "meta" informations (cue, chapters, tags, etc) only if
they are before the first cluster... Maybe a secondary option (when fast
load is selected) would be "load more meta" which would load usefull "meta"
data (cue, chapters, tags, etc) when they are specified in a Meta Seek
When fast load is not enabled, it should work the way Gabest does it right
now. But IMO it shouldn't be the default (too basic) behaviour.
