* the format FourCC as defined by ` ` drm_fourcc . h ` ` , e . g . NV12 is described as :
*
* YUV 4 : 2 : 0 image with a plane of 8 - bit Y samples followed by an
* interleaved U / V plane containing 8 - bit 2 x2 subsampled colour difference
* samples .
*
* So it would consist of a Y plane at ` ` offsets [ 0 ] ` ` and a UV plane at
