NAME
     mlibVideoInterpYS16U8 - half-pixel interpolation in the Y
     direction

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

     mlibstatus mlibVideoInterpYS16U8(mlibs16 *mcblock,
          const mlibu8 *refblock, mlibs32 width, mlibs32 height,
          mlibs32 frmstride, mlibs32 fldstride);


DESCRIPTION
     The mlibVideoInterpYS16U8() function performs  half-pixel
     interpolation  in  the  Y direction for a reference block of
     data type mlibu8 and a current block of data type mlibs16.
     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:

     mcblock      Pointer to  the  motion-compensated  reference
                   block. mcblock must be 8-byte aligned.


     refblock     Pointer to the reference block.


     width         Width of the blocks.


     height        Height of the blocks.


     frmstride    Stride, in bytes, between adjacent rows  in  a
                   frame  in the reference block. frmstride must
                   be a multiple of eight.


     fldstride    Stride, in bytes, between adjacent rows  in  a
                   field  in the reference block. fldstride must
                   be a multiple of eight.


RETURN VALUES
     The function returns MLIBSUCES if  successful.  Otherwise
     it returns MLIBFAILURE.
