info != chapter

info can be stored at 2 places
1. global & constant & repeated after every main/stream headers
2. local in an info stream

info SHOULD be stored in global packets instead of info streams if possible
and the amount of data is not large

noone wants 50mb of info packets at the file start nomatter what they contain
