NAME

mlib_VideoInterpX_U8_U8_16x16, mlib_VideoInterpX_U8_U8_16x8, mlib_VideoInterpX_U8_U8_8x16, mlib_VideoInterpX_U8_U8_8x8, mlib_VideoInterpX_U8_U8_8x4 - half-pixel interpolation in the X direction  

SYNOPSIS

cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>

mlib_status mlib_VideoInterpX_U8_U8_16x16(mlib_u8 *curr_block,
    const mlib_u8 *ref_block, mlib_s32 frm_stride,
    mlib_s32 fld_stride);

mlib_status mlib_VideoInterpX_U8_U8_16x8(mlib_u8 *curr_block,
    const mlib_u8 *ref_block, mlib_s32 frm_stride,
    mlib_s32 fld_stride);

mlib_status mlib_VideoInterpX_U8_U8_8x16(mlib_u8 *curr_block,
    const mlib_u8 *ref_block, mlib_s32 frm_stride,
    mlib_s32 fld_stride);

mlib_status mlib_VideoInterpX_U8_U8_8x8(mlib_u8 *curr_block,
    const mlib_u8 *ref_block, mlib_s32 frm_stride,
    mlib_s32 fld_stride);

mlib_status mlib_VideoInterpX_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 X direction 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 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 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.
