SYNOPSIS

12       mlib_status mlib_VideoInterpY_U8_U8(mlib_u8 *curr_block,
13            const mlib_u8 *ref_block, mlib_s32 width, mlib_s32 height,

DESCRIPTION

18       The  mlib_VideoInterpY_U8_U8()  function performs half-pixel interpola‐
19       tion in the Y direction for a reference block of data type mlib_u8  and
20       a  current block of data type mlib_u8. In this mode, the motion-compen‐
21       sated reference block becomes  the  current  block.  Thus,  the  stride
22       applies to both the input reference block and the current block.
23

PARAMETERS

25       The function takes the following arguments:
26
27       curr_block    Pointer  to  the current block. curr_block must be 8-byte
28                     aligned.
29
30
31       ref_block     Pointer to the reference block.
32
33
34       width         Width of the blocks.
35
36
37       height        Height of the blocks.
38
39
40       frm_stride    Stride, in bytes, between adjacent rows  in  a  frame  in
41                     both  the  current  block and reference block. frm_stride
42                     must be a multiple of eight.
43
44
45       fld_stride    Stride, in bytes, between adjacent rows  in  a  field  in
46                     both  the  current  block and reference block. fld_stride
47                     must be a multiple of eight.

49

RETURN VALUES

51       The function returns MLIB_SUCCESS if successful. Otherwise  it  returns
52       MLIB_FAILURE.
