SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_VideoColorBGR2JFIFYCC420(mlib_u8 *y0, mlib_u8 *y1,
mlib_u8 *cb, mlib_u8 *cr, const mlib_u8 *bgr0, const mlib_u8 *bgr1,
mlib_s32 n);
DESCRIPTION
The mlib_VideoColorBGR2JFIFYCC420() function performs color space con‐
version from BGR to YCbCr together with sampling rate conversion when
used in the JPEG File Interchange Format (JFIF).
PARAMETERS
The function takes the following arguments:
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.
bgr0 Pointer to upper source BGR multi-component row. bgr0 must be
8-byte aligned.
bgr1 Pointer to lower source BGR multi-component row. bgr1 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 BGR multi-com‐
ponent row must be 3*n.
RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns
MLIB_FAILURE.
