NAME
       mlib_VideoColorBGR2JFIFYCC422 - BGR to JFIF YCbCr color conversion

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

       mlib_status mlib_VideoColorBGR2JFIFYCC422(mlib_u8 *y, mlib_u8 *cb,
	   mlib_u8 *cr, const mlib_u8 *bgr, mlib_s32 n);

DESCRIPTION
       The  mlib_VideoColorBGR2JFIFYCC422() function performs color space con‐
       version from BGR to YCbCr together with sampling rate  conversion  when
       used in the JPEG File Interchange Format (JFIF).

PARAMETERS
       The function takes the following arguments:

       y      Pointer  to  destination	Y  component  row.  y  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.

       bgr    Pointer to source BGR multi-component row. bgr  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 BGR  multi-com‐
	      ponent row must be 3*n.

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