 It seems like there should be added a check for max value allowed by
 mplayer's boxblur filter, because otherwise it crashes.

 I have no debug ffmpeg build, so no gdb output.

 sws_param:
 [mp @ 01E63A20] This is a unholy filter, it will be purified by the ffmpeg

 which will change its syntax from dark -vf mp to light -vf.
 Thou shalst not make spells or scripts that depend on it
