NAME
     mlibVideoP64LoopU8U8 - applies a 2-dimensional  (2D)  3x3
     spatial filter on the reference block

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

     mlibstatus mlibVideoP64LoopU8U8(mlibu8 *currblock,
          const mlibu8 *refblock, mlibs32 stride);


DESCRIPTION
     The  mlibVideoP64LoopU8U8()   function   applies   a   2-
     dimensional  (2D) 3x3 spatial filter on the reference block.
     The filter is separable  into  1D  horizontal  and  vertical
     functions,  where  the  filter  coefficients  are 0.25, 0.5,
     0.25, except at the block edges where the  coefficients  are
     0,  1,  0.  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.


     refblock     Pointer to the reference block.


     stride        Stride, in bytes,  between  adjacent  rows  in
                   both  the  current  block  and  the  reference
                   block.


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