SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_VideoColorBGR2JFIFYCC422(mlib_u8 *y, mlib_u8 *cb,
mlib_u8 *cr, const mlib_u8 *bgr, mlib_s32 n);
DESCRIPTION
The mlib_VideoColorBGR2JFIFYCC422() 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:
y Pointer to destination Y component row. y 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.
bgr Pointer to source BGR multi-component row. bgr 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.
