NAME
       mlib_VideoColorARGB2JFIFYCC422 - ARGB to JFIF YCbCr color conversion

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

       mlib_status mlib_VideoColorARGB2JFIFYCC422(mlib_u8 *y, mlib_u8 *cb,
	    mlib_u8 *cr, const mlib_u8 *argb, mlib_s32 n);

DESCRIPTION
       The  mlib_VideoColorARGB2JFIFYCC422()  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:

       y       Pointer to destination Y component row. y 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.

       argb    Pointer to source ARGB multi-component row. argb 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.
