Planar/interleaved

Planar and interleaved are YUV pixel formats. Firstly, clarify that YUV pixel formats have 3 planes: Y (luma) – like gray scale, U and V (croma) – colors. These formats have various plane ordering.

The YUV components in planar format are grouped together. For example, the I420 format has the next group of components Y₁ … Y_n U₁ … U_n/4 V₁ … V_n/4.

In the interleaved format only the Y component is the same as in planar, but U and V are interleaved: Y₁ … Y_n U₁V₁ … U_n/4V_n/4 (NV12 format).

In addition, component order depends on subsampling.
