DESCRIPTION

41       Each of these functions performs  half-pixel  interpolation  in  the  X
42       direction  for  a  reference  block  of data type mlib_u8 and a current
43       block of data type mlib_s16. In this mode, the output of this  function
44       must  be  added to the IDCT output to reconstruct the block in the cur‐
45       rent frame. Thus, the stride applies only to the input reference block.
46

PARAMETERS

48       Each of the functions takes the following arguments:
49
50       mc_block      Pointer  to  the  motion-compensated   reference   block.
51                     mc_block must be 8-byte aligned.
52
53
54       ref_block     Pointer to the reference block.
55
56
57       frm_stride    Stride, in bytes, between adjacent rows in a frame in the
58                     reference block. frm_stride must be a multiple of eight.
59
60
61       fld_stride    Stride, in bytes, between adjacent rows in a field in the
62                     reference block. fld_stride must be a multiple of eight.
63
64

RETURN VALUES

66       Each  of the functions returns MLIB_SUCCESS if successful. Otherwise it
67       returns MLIB_FAILURE.
