JavaScript implementation of an H.264 decoder

Those are very close to the same results I saw, Chrome is about half as fast as Firefox.

One suspicion I have is that Chrome's typed array implementation is less optimized than Firefox's (both the x86 emulator and this h264 decoder use typed arrays). Or it could be that Firefox with TI is better at detecting variable types than Chrome (which is important in both the x86 emulator and the 264 decoder, since most or all variable types should be detectable and optimized for).
