#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.
