NAME
       mlib_VideoColorYUV422seq_to_UYVY422int - convert YUV sequential to interleaved

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

       void  mlib_VideoColorYUV422seq_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 dimen-
       sions  w  and  h.  The  U  and  V buffers have dimensions w/2 and h.  Dimensions w and h are assumed to be even.  Similar to mlib_VideoCol-
       orYUV420seq_to_UYVY422int() except U and V are not sampled in the h direction.

       The following equation is used:

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

       where r = 0, 1, 2, ..., h-1; 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.

       V	       Pointer to V input buffer.

       w	       Image width in pixels.

       h	       Image height in lines.

       dlb	       Linebytes for UYVY buffer.

       ylb	       Linebytes for Y buffer.

       uvlb	       Linebytes for U and V buffers.

RETURN VALUES
       None.
