[Red5devs] Ideas?

Youre not being ignored, you now understand why I wasnt able to finish
this.. not enough time in the day :)
The samples dont have to equal the chunks, to get a deeper understanding of
the atom structure of this format you will want to read this doc:
refs/qtff.pdf page 81. It will help you a great deal. (the refs directory is
in the branch)
