NAME
     mlib_VideoColorYUV411seq_to_ARGBint  -  color  convert   YUV
     sequential to ARGB interleaved

SYNOPSIS
     cc [ flag... ] file... -lmlib [ library... ]
     #include 

     void mlib_VideoColorYUV411seq_to_ARGBint(mlib_u32 *ARGB,
          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  ARGB  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 dimen-
              sions 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:

     ARGB       Pointer to output buffer.


     Y          Pointer to Y input buffer.
