Another example: If [videobox] was not in the picture, and a 640x480 image was
formatted at YUV420P, it seems clear that the color planes should have the
following dimensions:
  Y = 640x480
  U = 320x240
  V = 320x240

But what if it had been 641x480 image ?
  Y = 641x480 (or should it be 2-byte or 4-byte aligned to 642 or 644 ??)
  U = 320x480 (or should it have been 320, 322 ???)
  V = 320x480 (or should it have been 320, 322 ???)

There must be a specification somewhere for the YUV420 color scheme that defines
how to derive the dimensions of U & V planes when the Y play has odd dimensions.
 It must also say whether/not the dimensions need to be aligned to 1/2/4-bytes.

Then the allocation and population of the YUV420 buffer can be made the same in
[videobox] and [ffcolorspace]
