NAME
     mlib_VideoInterpY_S16_U8 - half-pixel interpolation in the Y
     direction

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

     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.
