NAME
mlib_VideoColorYUV411seq_to_ABGRint - color convert YUV sequential to ABGR interleaved
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
void mlib_VideoColorYUV411seq_to_ABGRint(mlib_u32 *ABGR, const mlib_u8 *Y, const mlib_u8 *U, const mlib_u8 *V, const mlib_u8 *A_array,
mlib_u8 A_const, mlib_s32 w, mlib_s32 h, mlib_s32 dlb, mlib_s32 yalb, mlib_s32 uvlb);
DESCRIPTION
The Y, U, V pixel streams are converted into an ABGR 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/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 alpha values for this function work in the following fashion:
o If A_array pointer is not NULL, the values are taken from there. It has to have the same dimensions as the Y buffer.
o If A_array pointer is NULL, the alpha values for every pixel are set to A_const.
The following equation is used:
|R| |1.1644 0.0000 1.5966| [|Y| | 16.0000|]
|G| = |1.1644 -0.3920 -0.8132| * [|U| - |128.0000|]
|B| |1.1644 2.0184 0.0000| [|V| |128.0000|]
PARAMETERS
The function takes the following arguments:
ABGR Pointer to output buffer.
Y Pointer to Y input buffer.
U Pointer to U input buffer.
V Pointer to V input buffer.
A_array Array of alpha values.
A_const Constant alpha value.
w Image width in pixels.
h Image height in lines.
dlb Linebytes for output buffer.
yalb Linebytes for Y and alpha buffers.
uvlb Linebytes for U and V buffers.
RETURN VALUES
None.
