AndroidYuv420_888

Three-Plane YUV 420 format commonly used by Android. See AIMAGE_FORMAT_YUV_420_888.

This format consists of three image planes. The first is the Y (luminocity) plane, with 8 bits per pixel. The second and third are the U and V (chromaticity) planes, respectively. Each 2x2 block of pixels share the same chromaticity value, so a given (x, y) pixel's chromaticity value is given by 

u = UPlane[(y / 2) * rowStride + (x / 2) * pixelStride];
v = VPlane[(y / 2) * rowStride + (x / 2) * pixelStride];

IosYpCbCr420_8BiPlanarFullRange

Bi-Planar Component Y'CbCr 8-bit 4:2:0, full-range (luma=[0,255] chroma=[1,255]) commonly used by iOS. See kCVPixelFormatType_420YpCbCr8BiPlanarFullRange.

This format consists of two image planes. The first is the Y (luminocity) plane, with 8 bits per pixel. The second plane is the UV (chromaticity) plane. The U and V chromaticity values are interleaved (u0, v0, u1, v1, etc.). Each 2x2 block of pixels share the same chromaticity values, so a given (x, y) pixel's chromaticity value is given by 

u = UvPlane[(y / 2) * rowStride + (x / 2) * pixelStride];
v = UvPlane[(y / 2) * rowStride + (x / 2) * pixelStride + 1];
pixelStride is always 2 for this format, so this can be optimized to 
u = UvPlane[(y >> 1) * rowStride + x & ~1];
v = UvPlane[(y >> 1) * rowStride + x | 1];
