direction and averaging for reference block
SYNOPSIS

#include <mlib.h>
mlib_status mlib_VideoInterpAveY_U8_U8_16x16(mlib_u8 *curr_block,

mlib_status mlib_VideoInterpAveY_U8_U8_8x16(mlib_u8 *curr_block,

mlib_status mlib_VideoInterpAveY_U8_U8_8x8(mlib_u8 *curr_block,
const mlib_u8 *ref_block, mlib_s32 frm_stride, mlib_s32 fld_stride);
mlib_status mlib_VideoInterpAveY_U8_U8_8x4(mlib_u8 *curr_block,
const mlib_u8 *ref_block, mlib_s32 frm_stride, mlib_s32 fld_stride);
DESCRIPTION
Each of these functions performs half-pixel interpolation in the Y
direction and averaging for a reference block of data type mlib_u8 and
a current block of data type mlib_u8. In this mode, the motion-compen‐
sated reference block becomes the current block. Thus, the stride
applies to both the input reference block and the current block.
PARAMETERS
Each of the functions takes the following arguments:
curr_block Pointer to the current block. curr_block must be 8-byte
aligned.
ref_block Pointer to the reference block.
frm_stride Stride, in bytes, between adjacent rows in a frame in
both the current block and the reference block.
frm_stride must be a multiple of eight.
fld_stride Stride, in bytes, between adjacent rows in a field in
both the current block and reference block. fld_stride
must be a multiple of eight.
RETURN VALUES
Each of the functions returns MLIB_SUCCESS if successful. Otherwise it
returns MLIB_FAILURE.
