MP4 container writer in Java

Question

I would like to find a FREE MP4 (container) writer for Java. I do not need an encoder, only something which can write the correct atoms given their expected values. Bonus

Answer 1

Even though my answer comes very late you could have a look into my MP4 Parser/Unparser at Github. You can parse MP4 files, modify them and write the result. You can even start from scratch creating boxes programatically and write your object representation to some sink.
