DESCRIPTION
Each of these functions performs half-pixel interpolation in
the Y direction and averaging for a reference block of datatype 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
Each of the functions 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.

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 referenceblock. fld_stride must be a multiple of eight.
RETURN VALUES
Each of the functions returns MLIB_SUCCESS if successful.
Otherwise it returns MLIB_FAILURE.
