NAME
     mlibVideoInterpAveYU8U8 - half-pixel interpolation in the
     Y direction and averaging for reference block

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

     mlibstatus mlibVideoInterpAveYU8U8(mlibu8 *currblock,
          const mlibu8 *refblock, mlibs32 width, mlibs32 height,
          mlibs32 frmstride, mlibs32 fldstride);


DESCRIPTION
     The  mlibVideoInterpAveYU8U8()  function  performs  half-
     pixel  interpolation  in the Y direction and averaging for a
     reference block of data type mlibu8 and a current block  of
     data  type  mlibu8.  In  this  mode, the motion-compensated
     reference block becomes the current block. Thus, the  stride
     applies  to  both  the input reference block and the current
     block.

PARAMETERS
     The function takes the following arguments:

     currblock    Pointer to the current block. currblock  must
                   be 8-byte aligned.


     refblock     Pointer to the reference block.


     width         Width of the blocks.


     height        Height of the blocks.


     frmstride    Stride, in bytes, between adjacent rows  in  a
                   frame in both the current block and the refer-
                   ence block. frmstride must be a  multiple  of
                   eight.


     fldstride    Stride, in bytes, between adjacent rows  in  a
                   field  in both the current block and reference
                   block. fldstride must be a multiple of eight.


RETURN VALUES
     The function returns MLIBSUCES if  successful.  Otherwise
     it returns MLIBFAILURE.
