NAME
     mlib_VideoColorABGR2JFIFYCC422 - ABGR to  JFIF  YCbCr  color
     conversion

SYNOPSIS
     cc [ flag... ] file... -lmlib [ library... ]
     #include 

     mlib_status mlib_VideoColorABGR2JFIFYCC422(mlib_u8 *y, mlib_u8 *cb,
          mlib_u8 *cr, const mlib_u8 *abgr, mlib_s32 n);


DESCRIPTION
     The mlib_VideoColorABGR2JFIFYCC422() function performs color
     space  conversion  from ABGR to YCbCr together with sampling
     rate conversion when used in the JPEG File Interchange  For-

             8-byte aligned.


     cr      Pointer to destination Cr component row. cr must  be
             8-byte aligned.


     abgr    Pointer to source  ABGR  multi-component  row.  abgr
             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 ABGR multi-component row must be 4*n.
