mlib_VideoColorJFIFYCC2RGB420(3MLIB)			    mediaLib Library Functions			      mlib_VideoColorJFIFYCC2RGB420(3MLIB)

NAME

       mlib_VideoColorJFIFYCC2RGB420 - JFIF YCbCr to RGB color conversion

SYNOPSIS

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

       mlib_status  mlib_VideoColorJFIFYCC2RGB420(mlib_u8  *rgb0,  mlib_u8  *rgb1, const mlib_u8 *y0, const mlib_u8 *y1, const mlib_u8 *cb0, const
       mlib_u8 *cr0, const mlib_u8 *cb1, const mlib_u8 *cr1, const mlib_u8 *cb2, const mlib_u8 *cr2, mlib_s32 n);

DESCRIPTION

       The mlib_VideoColorJFIFYCC2RGB420() function performs color space conversion from YCbCr to RGB together with sampling rate conversion  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.

       cb0	       Pointer to source upper Cb component row. cb0 must be 8-byte aligned.

       cr0	       Pointer to source upper Cr component row. cr0 must be 8-byte aligned.

       cb1	       Pointer to source middle Cb component row. cb1 must be 8-byte aligned.

       cr1	       Pointer to source middle Cr component row. cr1 must be 8-byte aligned.

       cb2	       Pointer to source lower Cb component row. cb2 must be 8-byte aligned.

       cr2	       Pointer to source lower Cr component row. cr2 must be 8-byte aligned.

       n	       Length of Y component row. The length of Cb and Cr component rows must be n. 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.
