Because C data types are signed by default, with the MSB being the sign indicator. So if you subtract 1 from 0 you get -1, or in binary
Code:
  0000 0000 (0)
- 0000 0001 (1)
-----------
  1111 1111 (-1)

mlib_videocoloruyv444int_to_argbint

mlib_VideoColorUYV444int_to_ARGBint(3MLIB)		    mediaLib Library Functions			mlib_VideoColorUYV444int_to_ARGBint(3MLIB)

NAME

       mlib_VideoColorUYV444int_to_ARGBint - color convert UYV interleaved to ARGB interleaved

SYNOPSIS

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

       void  mlib_VideoColorUYV444int_to_ARGBint(mlib_u32 *ARGB, const mlib_u8 *UYV, 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 UYV pixel stream is converted into an ARGB pixel stream. All pixel components are 8-bit unsigned integers. All buffers have	dimensions
       w and h.

       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:

       ARGB	       Pointer to output buffer.

       UYV	       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.
