Planar
I420
In I420, you have luma "luminance" planes Y and chroma samples U V.
In I420, chroma planes (blue and red) are subsampled in both the horizontal and vertical dimensions by a factor of 2.
For a 2x2 group of pixels, you have 4 Y samples and 1 U, 1 V sample.
YV12
YV12 is exactly like I420, but with U and V reversed.
