DESCRIPTION

18       The mlib_VideoP64Loop_U8_U8() function applies a 2-dimensional (2D) 3x3
19       spatial  filter on the reference block. The filter is separable into 1D
20       horizontal and vertical functions, where the  filter  coefficients  are
21       0.25,  0.5,  0.25, except at the block edges where the coefficients are
22       0, 1, 0. In this mode, the motion-compensated reference  block  becomes
23       the current block. Thus, the stride applies to both the input reference
24       block and the current block.
25

PARAMETERS

27       The function takes the following arguments:
28
29       curr_block    Pointer to the current block.
30
31
32       ref_block     Pointer to the reference block.
33
34
35       stride        Stride, in bytes, between adjacent rows in both the  cur‐
36                     rent block and the reference block.

RETURN VALUES

40       The  function  returns MLIB_SUCCESS if successful. Otherwise it returns
41       MLIB_FAILURE.
