Detailed Description

Defines constants for various color formats.

A color format is combination of color space, color depth, chroma subsampling, component layout and packing.

Enumerator
Unknown	The color format is not specified or unknown.
YV12	Planar Y, V, U (4:2:0) (note V,U order!)
NV12	Planar Y, merged U->V (4:2:0)
YUY2	Composite Y->U->Y->V (4:2:2)
UYVY	Composite U->Y->V->Y (4:2:2)
YUV411	Planar Y, U, V (4:1:1)
YUV420	Planar Y, U, V (4:2:0)
YUV422	Planar Y, U, V (4:2:2)
YUV444	Planar Y, U, V (4:4:4)
Y411	Composite Y, U, V (4:1:1)
Y41P	Composite Y, U, V (4:1:1)
BGR32	Composite B->G->R.
BGR24	Composite B->G->R.
BGR565	Composite B->G->R, 5 bit per B & R, 6 bit per G.
BGR555	Composite B->G->R->A, 5 bit per component, 1 bit per A.
BGR444	Composite B->G->R->A, 4 bit per component.
GRAY	Luminance component only.
YUV420A	Planar Y, U, V, Alpha.
YUV422A	Planar Y, U, V, Alpha.
YUV444A	Planar Y, U, V, Alpha.
YVU9	Planar Y, V, U The vertical subsampling interval is 4. The horizontal subsampling interval is also 4 This means that a single V and a single U sample are taken for each square block of 16 image pixels. Effectively this averages 9 bits per pixel (16 pixels => 16Y + 1V + 1U => 144bits => 9bits/pixel)
BGRA32	Composite B->G->R->A.
