NAME
     mlib_VideoP64Loop_U8_U8 - applies a 2-dimensional  (2D)  3x3
     spatial filter on the reference block

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

     mlib_status mlib_VideoP64Loop_U8_U8(mlib_u8 *curr_block,
          const mlib_u8 *ref_block, mlib_s32 stride);


DESCRIPTION
     The  mlib_VideoP64Loop_U8_U8()   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:

     curr_block    Pointer to the current block.


     ref_block     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 MLIB_SUCCESS if  successful.  Otherwise
     it returns MLIB_FAILURE.
