There's your answer. YUV is a planar format. You get a whole frame of 
brightness at full resolution, and then you get a whole frame of one 
color channel at one quarter resolution, and you get a whole frame of 
the other color channel at one quarter resolution. Data from the three 
different channels comes sequentially, not interspersed. It really, 
truly, is reading 8-bit data.
