DESCRIPTION

36       Each of these functions performs  half-pixel  interpolation  in  the  Y
37       direction  and averaging for a reference block of data type mlib_u8 and
38       a current block of data type mlib_u8. In this mode, the  motion-compen‐
39       sated  reference  block  becomes  the  current  block. Thus, the stride
40       applies to both the input reference block and the current block.
41

PARAMETERS

43       Each of the functions takes the following arguments:
44
45       curr_block    Pointer to the current block. curr_block must  be  8-byte
46                     aligned.
47
48
49       ref_block     Pointer to the reference block.
50
51
52       frm_stride    Stride,  in  bytes,  between  adjacent rows in a frame in
53                     both  the  current  block  and   the   reference   block.
54                     frm_stride must be a multiple of eight.
55
56
57       fld_stride    Stride,  in  bytes,  between  adjacent rows in a field in
58                     both the current block and  reference  block.  fld_stride
59                     must be a multiple of eight.

61

RETURN VALUES

63       Each  of the functions returns MLIB_SUCCESS if successful. Otherwise it
64       returns MLIB_FAILURE.
