Why would the instruction set used by the kernel matter, when video encoding
is done in userspace?  You would get more improvement if you recompiled
the software that does the video encoding - and as I mentioned, it won't help
unless the compiler knows about the opcodes *and* can recognize the spots
in the userspace code where those opcodes would be useful.
