* Luma MC is not bitexact because of rounding issues (i.e. you can't replace
filtering with separate vertical and horizontal passes).
See JVT document Q15-J-08 for details.
* P-frame filter invoking is still a bit wrong, but the edges chosen for
filtering are filtered correctly.
* Motion vector prediction in B-frames is not correct.
