SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_VideoColorJFIFYCC2RGB420(mlib_u8 *rgb0,
mlib_u8 *rgb1, const mlib_u8 *y0,
const mlib_u8 *y1, const mlib_u8 *cb0,

DESCRIPTION
The mlib_VideoColorJFIFYCC2RGB420() function performs color space conversion from YCbCr to RGB together with sampling rate conversion when used in the JPEG File Interchange Format (JFIF).
PARAMETERS
The function takes the following arguments:
rgb0
-
Pointer to upper destination RGB multi-component row. rgb0 must be 8-byte aligned.
rgb1
-
Pointer to lower destination RGB multi-component row. rgb1 must be 8-byte aligned.
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.
cb0
-
Pointer to source upper Cb component row. cb0 must be 8-byte aligned.
cr0
-
Pointer to source upper Cr component row. cr0 must be 8-byte aligned.
cb1
-
Pointer to source middle Cb component row. cb1 must be 8-byte aligned.
cr1
-
Pointer to source middle Cr component row. cr1 must be 8-byte aligned.
cb2
-
Pointer to source lower Cb component row. cb2 must be 8-byte aligned.
cr2
-
Pointer to source lower Cr component row. cr2 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 RGB multi-component row must be 3*n.
RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
