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.h>

       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.
