```mlib_VideoColorYUV411seq_to_YUYV422int(3MLIB)		    mediaLib Library Functions		     mlib_VideoColorYUV411seq_to_YUYV422int(3MLIB)

NAME
mlib_VideoColorYUV411seq_to_YUYV422int - convert YUV sequential to interleaved

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

void  mlib_VideoColorYUV411seq_to_YUYV422int(mlib_u32  *YUYV, 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 YUYV 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/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 following equation is used:

YUYV[r][c/2]   = (Y[r][c]   << 24) |
(U[r][c/4] << 16) |
(Y[r][c+1] << 8) |
(V[r][c/4])

YUYV[r][c/2+1] = (Y[r][c+2] << 24) |
(U[r][c/4] << 16) |
(Y[r][c+3] << 8) |
(V[r][c/4])

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.

V	       Pointer to V input buffer.

w	       Image width in pixels.

h	       Image height in lines.

dlb	       Linebytes for YUYV buffer.

ylb	       Linebytes for Y buffer.

uvlb	       Linebytes for U and V buffers.

RETURN VALUES
None.

NAME
mlib_VideoColorYUV422seq_to_YUYV422int - convert YUV sequential to interleaved

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

void mlib_VideoColorYUV422seq_to_YUYV422int(mlib_u32 *YUYV,
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 YUYV 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_YUYV422int() except U and V are not sampled in the h direction.

The following equation is used:

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

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

V       Pointer to V input buffer.

w       Image width in pixels.

h       Image height in lines.

dlb     Linebytes for YUYV buffer.

ylb     Linebytes for Y buffer.

uvlb    Linebytes for U and V buffers.

RETURN VALUES
None.
