The format is very simple. For each pixel you have two bytes (even: Y and U)
or (odd: U and V). So for an image of 4x4, you have 32 bytes

 0: YU YV YU YV
 8: YU YV YU YV
16: YU YV YU YV
24: YU YV YU YV

This is very simple but i've not (yet) found a good algorithm when resizing
and converting to other colorspace. You see vertical line. One line will be
blue, the other line will be green.
