NAME
       mlib_VideoColorYUV2RGB420 - YUV to RGB color conversion

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.
