SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_VideoColorYUV2RGB420(mlib_u8 *rgb, const mlib_u8 *y,
const mlib_u8 *u, const mlib_u8 *v, mlib_s32 width, mlib_s32 height,
mlib_s32 rgb_stride, mlib_s32 y_stride, mlib_s32 uv_stride);
DESCRIPTION
The mlib_VideoColorYUV2RGB420() function performs YUV to RGB color con‐
version used in MPEG1 and MPEG2 video compression in the 4:2:0
sequence.
The luminance component is stored in Y, the chrominance components are
stored in U and V, respectively. The size of the chrominance image
depends on the chroma format used by the sequence. In this sequence,
the chrominance components are subsampled 2-to-1 in both the horizontal
and vertical directions in respect to the luminance component.
PARAMETERS
The function takes the following arguments:
rgb Pointer to the destination RGB image.
y Pointer to the source Y component.
u Pointer to the source U component.
v Pointer to the source V component.
width Width of the image.
height Height of the image.
rgb_stride Stride, in bytes, between adjacent rows in the destina‐
tion image.
y_stride Stride, in bytes, between adjacent rows in the Y compo‐
nent image.
uv_stride Stride, in bytes, between adjacent rows in the U and V
component images.
RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns
MLIB_FAILURE.
