NAME
     mlib_VideoColorYUV420seq_to_UYVY422int - convert YUV sequen-
     tial to interleaved

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

     void mlib_VideoColorYUV420seq_to_UYVY422int(mlib_u32 *UYVY,
          const mlib_u8 *Y,const mlib_u8 *U, const mlib_u8 *V,
          mlib_s32 w, mlib_s32 h, mlib_s32 dlb,
          mlib_s32 ylb, mlib_s32 uvlb);


DESCRIPTION
     The Y, U, V pixel streams are combined  into  a  UYVY  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  UYVY  use
     successive rows of Y and the same rows of U and V.


     The following equation is used:

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

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



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

PARAMETERS
     The function takes the following arguments:

     UYVY    Pointer to output buffer.


     Y       Pointer to Y input buffer.


     U       Pointer to U input buffer.
