NAME
mlib_VideoInterpAveY_U8_U8 - half-pixel interpolation in the Y direc‐
tion and averaging for reference block
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_VideoInterpAveY_U8_U8(mlib_u8 *curr_block,
const mlib_u8 *ref_block, mlib_s32 width, mlib_s32 height,
mlib_s32 frm_stride, mlib_s32 fld_stride);
DESCRIPTION
The mlib_VideoInterpAveY_U8_U8() function performs half-pixel interpo‐
lation 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-compensated reference block becomes the current block.
Thus, the stride applies to both the input reference block and the cur‐
rent block.
PARAMETERS
The function 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.
width Width of the blocks.
height Height of the blocks.
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
The function returns MLIB_SUCCESS if successful. Otherwise it returns
MLIB_FAILURE.
