NAME
       mlib_VideoColorYUV2ARGB420 - YUV to RGB color conversion

SYNOPSIS
       cc [ flag... ] file... -lmlib [ library... ]
       #include <mlib.h>

       mlib_status mlib_VideoColorYUV2ARGB420(mlib_u8 *argb, 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_VideoColorYUV2ARGB420()  function  performs  YUV  to  RGB color conversion 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 horizon-
       tal and vertical directions in respect to the luminance component.

PARAMETERS
       The function takes the following arguments:

       argb	     Pointer to the destination packed ARGB 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 destination image.

       y_stride      Stride, in bytes, between adjacent rows in the Y component 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.
