Planar
YUV 4:2:0 (I420/YV12)
I420
In I420, you have luma "luminance" planes Y and chroma planes 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 and 1 V sample.
YV12
YV12 is exactly like I420, but with U and V order reversed.
NV12/NV21
NV12
Related to I420, in NV12, you have one luma "luminance" planes Y and one plane with U and V data interleaved. NV12 is considered as semiplanar.
In NV12, 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 and 1 V sample.
NV21
NV21 is like NV12, but with U and V order reversed: it starts with V
