NAME
       mlib_VideoInterpXY_S16_U8 - half-pixel interpolation in the X and Y directions

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

       mlib_status mlib_VideoInterpXY_S16_U8(mlib_s16 *mc_block,
	    const mlib_u8 *ref_block, mlib_s32 width, mlib_s32 height,
	    mlib_s32 frm_stride, mlib_s32 fld_stride);

DESCRIPTION
       The  mlib_VideoInterpXY_S16_U8()  function  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  recon-
       struct the block in the current frame. Thus, the stride applies only to the input reference block.

PARAMETERS
       The function 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.

       width	     Width of the blocks.

       height	     Height of the blocks.

       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
       The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
