The broadcom card is a commercial product that is well documented.
We are pretty lucky that it can do h264 at all. It is only through the hard work of the devs (Davilla et al) that they managed to reverse engineer the hardware decoding API as far as they have. Potentially the hardware has all the goodies to do other formats but Apple in their typically Apple way have gone all out to keep it a secret from evil people who try to sully the perfection of their products.
To be fair, it's not that they've gone out of their way to keep this info secret.. there's just no motivation for them to document and publish it.
