#include <mlib.h>
mlib_status mlib_VideoInterpXY_S16_U8_16x16(mlib_s16 *mc_block,

mlib_status mlib_VideoInterpXY_S16_U8_8x8(mlib_s16 *mc_block,
const mlib_u8 *ref_block, mlib_s32 frm_stride,
mlib_s32 fld_stride);
mlib_status mlib_VideoInterpXY_S16_U8_8x4(mlib_s16 *mc_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 and
Y directions for a reference block of data type mlib_u8 and a current
block of data type mlib_s16. In this mode, the output of this function
must be added to the IDCT output to reconstruct the block in the cur‐
rent frame. Thus, the stride applies only to the input reference
block.
PARAMETERS
Each of the functions takes the following arguments:
mc_block Pointer to the motion-compensated reference block.
mc_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 the
reference block. frm_stride must be a multiple of eight.
fld_stride Stride, in bytes, between adjacent rows in a field in the
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.
