31 
           YYYY UU YYYY UU   even lines
32 
           YYYY VV YYYY VV   odd lines
33 
           U/V data is subsampled by 2 both in horizontal
34 
           and vertical directions, and intermixed with the Y values.

   420p = "4:2:0 planar"

40 
           U/V is again subsampled, but all the Ys, Us and Vs are placed
41 
           together in separate buffers. The buffers may be placed in
42 
           one piece of contiguous memory though, with Y buffer first,
43 
           followed by U, followed by V.

   yuyv = "4:2:2 interlaced"

           The U/V data is subsampled by 2 in horizontal direction only.

   bgr24 = 3 bytes per pixel, in the order Blue Green Red (whoever came up
50 
           with that idea...)
51 
   rgb24 = 3 bytes per pixel, in the order Red Green Blue (which is sensible)
52 
   rgb32 = 4 bytes per pixel, in the order Red Green Blue Alpha, with
53 
           Alpha really being a filler byte (0)
54 
   bgr32 = last but not least, 4 bytes per pixel, in the order Blue Green Red
55 
           Alpha, Alpha again a filler byte (0)
