[FFmpeg-user] hyperthreading support

[Joshua Grauman]

Thanks. Yes, you are right. I was thinking it might have an enhanced 
instruction set. But it's just improved in clock speed, L3 cache, and HT. 
So since I know what the improvement in clock speed looks like, I was 
trying to figure out the other improvements, but you guys answered it all. 
Thanks!
