     mlibVideoInterpAveYU8U88x16,

     mlibVideoInterpAveYU8U88x4 - half-pixel interpolation in
     the Y direction and averaging for reference block

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

     mlibstatus mlibVideoInterpAveYU8U816x16(mlibu8 *currblock,
          const mlibu8 *refblock, mlibs32 frmstride, mlibs32 fldstride);


     mlibstatus mlibVideoInterpAveYU8U816x8(mlibu8 *currblock,
          const mlibu8 *refblock, mlibs32 frmstride, mlibs32 fldstride);


     mlibstatus mlibVideoInterpAveYU8U88x16(mlibu8 *currblock,
          const mlibu8 *refblock, mlibs32 frmstride, mlibs32 fldstride);


     mlibstatus mlibVideoInterpAveYU8U88x8(mlibu8 *currblock,
          const mlibu8 *refblock, mlibs32 frmstride, mlibs32 fldstride);


     mlibstatus mlibVideoInterpAveYU8U88x4(mlibu8 *currblock,
          const mlibu8 *refblock, mlibs32 frmstride, mlibs32 fldstride);


DESCRIPTION
     Each of these functions performs half-pixel interpolation in
     the  Y direction and averaging for a reference block of data
     type mlibu8 and a current block of data  type  mlibu8.  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
     Each of the functions takes the following arguments:

     currblock    Pointer to the current block. currblock  must
                   be 8-byte aligned.


     refblock     Pointer to the reference block.

     frmstride    Stride, in bytes, between adjacent rows  in  a
                   frame in both the current block and the refer-
                   ence block. frmstride must be a  multiple  of
                   eight.


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


RETURN VALUES
     Each of the functions returns  MLIBSUCES  if  successful.
     Otherwise it returns MLIBFAILURE.
