No, I've never worked with it.

I've searched online a bit and couldn't find a
specification/description of the codec internals, I guess it is
because of patents. I don't know exactly what a "frame parser" is, so
I am clueless about how to start it. However, I'm interested in giving
it a try if you could point a way to help me develop the task.
