-Note that the image buffers saved in `raspistillyuv` are padded to a horizontal size divisible by 16 (so there may be unused bytes at the end of each line to make the width divisible by 16). Buffers are also padded vertically to be divisible by 16, and in the YUV mode, each plane of Y,U,V is padded in this way.
