You mean the centerpoint chroma location (top-left, top-middle, middle-middle, etc.) respective to the set of luma pixels? If that's all, that's a mere few seconds to implement in swscale, correctly for all cases (you just offset the start of the filter). You don't need special filters just for that. I bet Michael or me could do this in 15 minutes.
