 Summary of the bug: I try to stabilize various videos and I am checking
 different vidstabdetect options.

 First I stabilized video with shakiness=1 and stepsize=1 (min values),
 then I stabilized the same video with shakiness=10 and stepsize=6 (max
 value). Finally I compared two videos with kdenlive "difference"
 transition and there was no difference (black screen). Therefore, my
 conclusion is that shakiness and stepsize options do not work.

 How to reproduce:
 {{{
 % ffmpeg -i input -vf
 vidstabdetect=shakiness=1:stepsize=1:result=video.xml -f null out.null
 ffmpeg version N-77953-gcc83177
 built with gcc 5.2.0 (GCC)
 ffmpeg-20160119-git-cc83177-win64-static.7z
 }}}
 Patches should be submitted to the ffmpeg-devel mailing list and not this
 bug tracker.
