NAME
       mlib_VideoColorYUV411seq_to_ABGRint - color convert YUV sequential to ABGR interleaved

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

       void mlib_VideoColorYUV411seq_to_ABGRint(mlib_u32 *ABGR,
	    const mlib_u8 *Y, const mlib_u8 *U, const mlib_u8 *V,
	    const mlib_u8 *A_array, mlib_u8 A_const,
	    mlib_s32 w, mlib_s32 h, mlib_s32 dlb,
	    mlib_s32 yalb, mlib_s32 uvlb);

DESCRIPTION
       The  Y,	U,  V  pixel  streams  are converted into an ABGR pixel stream. All pixel components are 8-bit unsigned integers. The Y buffer has
       dimensions w and h. The U and V buffers have dimensions w/4 and h. Dimension w is assumed to be a multiple of 4. In each  row,  every  4  Y
       values use the same U and V values.

       The alpha values for this function work in the following fashion:

	   o	  If A_array pointer is not NULL, the values are taken from there. It has to have the same dimensions as the Y buffer.

	   o	  If A_array pointer is NULL, the alpha values for every pixel are set to A_const.

       The following equation is used:

	 |R|   |1.1644	0.0000	1.5966|   [|Y|	 | 16.0000|]
	 |G| = |1.1644 -0.3920 -0.8132| * [|U| - |128.0000|]
	 |B|   |1.1644	2.0184	0.0000|   [|V|	 |128.0000|]

PARAMETERS
       The function takes the following arguments:

       ABGR	  Pointer to output buffer.

       Y	  Pointer to Y input buffer.

       U	  Pointer to U input buffer.

       V	  Pointer to V input buffer.

       A_array	  Array of alpha values.

       A_const	  Constant alpha value.

       w	  Image width in pixels.

       h	  Image height in lines.

       dlb	  Linebytes for output buffer.

       yalb	  Linebytes for Y and alpha buffers.

       uvlb	  Linebytes for U and V buffers.

RETURN VALUES
       None.
