I got some more problems.

Is index per stream or not?... There's just a SINGLE index, for a SINGLE 
stream in the file?

What about subtitles? There's no defined way in the spec to write them. I 
think they should basically be a stream header and a 2 letter language... 
Something like that. Perhaps encoding too?

What does 'metadata' mean?..
stream_class
        0       video
        1       audio
        2       subtiles
        3       metadata

Also, I have a request - add a last_pts field in the index. so we can know 
the precise total length of the video without weird hacks like seeking to 
last frame...

I'm almost done with my muxer implementation. Stuck on index because of 
this, still haven't implemented info packets, and it has one slight 
disadvantage, it reuiqres the caller to be quite smart (all timestamp 
handling is done by caller).
