Planar or 3-Plane Format
An image is described by 3 pointer values (Py, Pu, Pv). Each pointer points to a 2D
array of Y, U and V values as shown in
Semi-Planar or 2-Plane Format
An image is described by 2 pointer values (Py, Puv). The Y pointer points to a 2D
array of Y values. The Puv pointer points to a 2D array of UV pair values. Note that
the U value of a UV pair always has the lower byte address. See
