The only one I know of is the Hardh.264 encoder also known as the Zexia.
This is on sourceforge, but only a handful of people have downloaded it. Unfortunately my Uni project scope is so much bigger than compression so I can't allow it to consume all my time.
Unless someone can help, for the time being I have to back burn this until i attack the rest of my scope.
Note there is a big difference between decoders and encoders. Encoders are far more complex.
Doddy. I've replied to your PM and can send you all the fruits of my compression research. This is avaliable for anyone else if they wish, it should definately give you a leg up. As stated i'll be able to support you through your work, i just can't put all my time to it thats all.
