NAME
       mlib_VideoColorRGB2JFIFYCC420 - RGB to JFIF YCbCr color conversion

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

       mlib_status  mlib_VideoColorRGB2JFIFYCC420(mlib_u8  *y0,  mlib_u8  *y1, mlib_u8 *cb, mlib_u8 *cr, const mlib_u8 *rgb0, const mlib_u8 *rgb1,
       mlib_s32 n);

DESCRIPTION
       The mlib_VideoColorRGB2JFIFYCC420() function performs color space conversion from RGB to YCbCr to 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.

       rgb0	       Pointer to upper source RGB multi-component row. rgb0 must be 8-byte aligned.

       rgb1	       Pointer to lower source RGB multi-component row. rgb1 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 RGB multi-
		       component row must be 3*n.

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