[Matroska-devel] Compression track 3

Hi (again),

Another addition for the coming days in Matroska is the new compression 
feature of each track. The idea is to strip the header of each frame in 
the track, because that header is always the same. It's then readded on 
playback.

This feature could seem like ridiculous if you only gain 1 byte per 
Block. But for a movie of 1h30 you could save 150 KB on an MP3 track. 
And for MPEG4 part 2 (25 fps, 4 bytes saved) it's 540 KB.

This feature is already working in Haali's experimental. We now have to 
implement it in mkvmerge and VLC.
