Sure, that would be very easy to implement (a couple lines of code).

Note that http://git.videolan.org/?p=x264.git;a=commit;h=f7bfcfaa36ac3f04447f668f94db73801ca86e4d
made motion estimation code significantly more complicated (for
optimization purposes); feel free to roll it back locally if it makes
things easier.
