NAME
     mlib_VideoInterpAveY_U8_U8 - half-pixel interpolation in the
     Y direction and averaging for reference block

SYNOPSIS
     cc [ flag... ] file... -lmlib [ library... ]
     #include 

     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  interpolation  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 current
     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 refer-
                   ence 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.
