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 coefficients 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.
