NAME
       mlib_VideoColorRGB2JFIFYCC422 - RGB to JFIF YCbCr color conversion

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

       mlib_status mlib_VideoColorRGB2JFIFYCC422(mlib_u8 *y, mlib_u8 *cb,
	    mlib_u8 *cr, const mlib_u8 *rgb, mlib_s32 n);

DESCRIPTION
       The  mlib_VideoColorRGB2JFIFYCC422() function performs color space conversion from RGB to YCbCr together with sampling rate conversion when
