NAME
       mlib_VideoP64Loop_S16_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_S16_U8(mlib_s16 mc_block[64],
	    const mlib_u8 *ref_block, mlib_s32 stride);

DESCRIPTION
       The  mlib_VideoP64Loop_S16_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  coeffi-
       cients  are  0,	1,  0.	In this mode, the output must be added to the IDCT output to reconstruct the block in the current frame. Thus, the
       stride applies only to the input reference block. This function requires the motion-compensated block to be 8-bit aligned.

PARAMETERS
       The function takes the following arguments:

       mc_block     Pointer to the motion-compensated reference block.

       ref_block    Pointer to the reference block.

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

RETURN VALUES
       The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
