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. Dimen‐
sions 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.
