[x264-devel] About the interpolation process in x264

[zhihang wang]

I have asked the question here about the following comments in x264 in the
function
 void x264_frame_expand_border_filtered( x264_t *h, x264_frame_t *frame, int
mb_y, int b_end )

     /* during filtering, 8 extra pixels were filtered on each edge,
      * but up to 3 of the horizontal ones may be wrong.
        we want to expand border from the last filtered pixel */
 I don't think there are some errors in the interpolation process
 So I don't know the meaning of the second line of the comments
 I dump out the interpolation results of h, v, c, to 3 files
 It verifies my results.
the three files are here
 Would someone like to explain?
