#include <mlib.h>

void mlib_VideoColorUYVY422int_to_ARGBint(mlib_u32 *ARGB,
     const mlib_u32 *UYVY, const mlib_u8 *A_array,
     mlib_u8 A_const, mlib_s32 w, mlib_s32 h,
     mlib_s32 dlb, mlib_s32 slb, mlib_s32 alb);

Description

The UYVY pixel stream is converted into an ARGB pixel stream. All pixel components are 8-bit unsigned integers. The UYVY buffer has dimensions w/2 and h. The ARGB buffer has dimensions w and h. Dimension w is assumed to be even.

The alpha values for this function work in the following fashion:

• If A_array pointer is not NULL, the values are taken from there. It has to have the same dimensions as the Y buffer.

• 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:

ARGB

Pointer to output buffer.

UYVY

Pointer to 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.

slb

Linebytes for input buffer.

alb

Linebytes for alpha buffer.

Return Values

None.
