NAME
     mlibVideoColorYUV420seqtoYUYV422int - convert YUV sequen-
     tial to interleaved

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

     void mlibVideoColorYUV420seqtoYUYV422int(mlibu32 *YUYV
          const mlibu8 *Y, const mlibu8 *U, const mlibu8 *V,
          mlibs32 w, mlibs32 h, mlibs32 dlb,
          mlibs32 ylb, mlibs32 uvlb);


DESCRIPTION
     The Y, U, V pixel streams are combined  into  a  YUYV  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/2 and h/2. Dimensions w and h are assumed
     to be even. Successive rows of the output  buffer  YUYV  use
     successive rows of Y and the same rows of U and V.


     The following equation is used:

       YUYV[r][c/2]   = (Y[r][c]     << 24) 
                        (U[r/2][c/2] << 16) 
                        (Y[r][c]1]   << 8) 
                        (V[r/2][c/2])

       YUYV[r]1][c/2] = (Y[r]1][c]   << 24) 
                        (U[r/2][c/2] << 16) 
                        (Y[r]1][c]1] << 8) 
                        (V[r/2][c/2])



     where r = 0, 2, 4, ..., h-2; and c = 0, 2, 4, ..., w-2.

PARAMETERS
     The function takes the following arguments:

     YUYV    Pointer to output buffer.


     Y       Pointer to Y input buffer.


     U       Pointer to U input buffer.
