NAME
       mlib_VideoColorARGB2JFIFYCC420 - ARGB to JFIF YCbCr color conversion

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

       mlib_status mlib_VideoColorARGB2JFIFYCC420(mlib_u8 *y0,
	    mlib_u8 *y1, mlib_u8 *cb, mlib_u8 *cr, const mlib_u8 *argb0,
	    const mlib_u8 *argb1, mlib_s32 n);

DESCRIPTION
       The  mlib_VideoColorARGB2JFIFYCC420()  function	performs  color space conversion from ARGB to YCbCr together with sampling rate conversion
       when used in the JPEG File Interchange Format (JFIF).

PARAMETERS
       The function takes the following arguments:

       y0	Pointer to upper destination Y component row. y0 must be 8-byte aligned.

       y1	Pointer to lower destination Y component row. y1 must be 8-byte aligned.

       cb	Pointer to destination Cb component row. cb must be 8-byte aligned.

       cr	Pointer to destination Cr component row. cr must be 8-byte aligned.

       argb0	Pointer to upper source ARGB multi-component row. argb0 must be 8-byte aligned.

       argb1	Pointer to lower source ARGB multi-component row. argb1 must be 8-byte aligned.

       n	Length of Y component row. n must be even. The length of Cb and Cr component rows must be n/2. The length of the ARGB multi-compo-
		nent row must be 4*n.

RETURN VALUES
       The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
