cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_VideoColorABGR2JFIFYCC420(mlib_u8 *y0,
mlib_u8 *y1, mlib_u8 *cb, mlib_u8 *cr, const mlib_u8 *abgr0,
const mlib_u8 *abgr1, mlib_s32 n);
DESCRIPTION
The mlib_VideoColorABGR2JFIFYCC420() function performs color space conversion from ABGR to YCbCr together with sampling rate conversion
when used in the JPEG File Interchange Format (JFIF).
PARAMETERS

y0 Pointer to upper destination Y component row. y0 must be 8-byte aligned.
y1 Pointer to lower destination Y component row. y1 must be 8-byte aligned.
cb Pointer to destination Cb component row. cb must be 8-byte aligned.
cr Pointer to destination Cr component row. cr must be 8-byte aligned.
abgr0 Pointer to upper source ABGR multi-component row. abgr0 must be 8-byte aligned.
abgr1 Pointer to lower source ABGR multi-component row. abgr1 must be 8-byte aligned.
n Length of Y component row. n must be even. The length of Cb and Cr component rows must be n/2. The length of the ABGR multi-compo-
nent row must be 4*n.
