Sure, but even still coreavc is still a good bit faster, and with
h264, every little bit helps.

Here you go, not a lot of difference though:
640x360_no_b.avi:      AVC:  11.6083 FFh264:  15.1547 Diff:  23.40%
640x360_no_b_t2.avi: AVC:  11.1777 FFh264:  15.2310 Diff:  26.61%
640x360_no_b_t4.avi: AVC:  11.2170 FFh264:  15.4130 Diff:  27.22%

I guess this has left the mplayer domain now, but if there is any
information I can provide that will help make ffh264 better, I'll be
happy to help.  I'd love to see ffh264 perfomance on par with CoreAVC.
