 Summary of the bug:\\
 \\
 If you apply the "sharpen_npp" filter to a 1080p video, the resolution
 will be output at 1088p (a green bar will appear at the bottom of the
 video)\\
 \\
 It looks similar to the problem below, but in my environment it looks like
 a "shapen_npp" problem.
 This is because the problem does not occur if "shapen_npp" is not used.
