Detailed Description

getID3() by James Heinrich info@.nosp@m.geti.nosp@m.d3.or.nosp@m.g //

@tutorial http://www.matroska.org/technical/specs/index.html

Todo:

Rewrite EBML parser to reduce it's size and honor default element values

After rewrite implement stream size calculation, that will provide additional useful info and enable AAC/FLAC audio bitrate detection
