About a 20% speed gain by using coreavc in this case, quite noticable on our 
limited hardware. Even skipping inloop filter for ffh264 doesn't get it up 
anywhere near the speed of coreavc. I wonder what industry secret they are 
using. If you are interested in tests on specific samples let me know.
