No, it really isn't.  There is a world of difference between implementing something and making an API to it public or available.  Good grief.

> Whether you need to implement a new API or simply expose existing an implementation, it takes months for users to upgrade to this new version and for it to actually work as expected (initial releases tend to be unstable or missing features). Furthermore, there is no guarantee that Apple will release said API anytime soon. For these reasons, I stand by my comment that real-time H.264 support does not exist (for developers outside of Apple).
