NAME
       mlib_VideoColorJFIFYCC2RGB420_Nearest - JFIF YCbCr to RGB color conversion

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

       mlib_status mlib_VideoColorJFIFYCC2RGB420_Nearest(mlib_u8 *rgb0,
	    mlib_u8 *rgb1, const mlib_u8 *y0,
	    const mlib_u8 *y1, const mlib_u8 *cb,
	    const mlib_u8 *cr, mlib_s32 n);

DESCRIPTION
       The  mlib_VideoColorJFIFYCC2RGB420_Nearest() function performs color space conversion from YCbCr to RGB together with sampling rate conver-
       sion when used in the JPEG File Interchange Format (JFIF).

PARAMETERS
       The function takes the following arguments:

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

       rgb1    Pointer to lower destination RGB multi-component row. rgb1 must be 8-byte aligned.

       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 source Cb component row. cb must be 8-byte aligned.

       cr      Pointer to source Cr component row. cr 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-compo-
	       nent row must be 3*n.

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