been talking to michael on irc, so here are some updates:

bad and not useful.

scratch this and replace them with a "Disposition" tag in the info
packet. possible values for audio are orig/dub/com[mentary] and
possibly other additions. for text, sub/com/karaoke and possibly
others.

to make sure the player can actually get this information at startup
time, require info packets to immediately follow headers.

plus, a couple more:

- specify rules for header repetition:

working rule so far: demuxer SHOULD look for headers at beginning and
end of file, and beginning at offsets 2^n (for each n) in the file,
and stop upon finding the first startcode.

- specify subtitle stream header and muxing

- specify guidelines for max_distance and max_short_distance

so far, defaults should be 4k and 32k, and should not exceed double
that without good reason.
