mlib_VideoColorARGB2JFIFYCC420(3MLIB)			    mediaLib Library Functions			     mlib_VideoColorARGB2JFIFYCC420(3MLIB)

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 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.

       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 RGB multi-
		       component row must be 3*n.

RETURN VALUES

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