NAME
       mlib_VideoInterpY_S16_U8 - half-pixel interpolation in the Y direction

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

       mlib_status mlib_VideoInterpY_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_VideoInterpY_S16_U8() function performs half-pixel interpolation in the Y direction 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 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.
