 Replying to [comment:8 cehoyos]:
 > Works even better with "-cpuflags -sse2 -vf deshake=rx=63:ry=64"

 But it is not even close from what the proposed link shows. Also, this
 configuration makes it very slow to be used on realtime.

 A good deshake filter should add the possibility to crop the image instead
 of filling it with surrounding pixels.

 Try adding "crop=600:400" after the deshake filter to see a better result.
 This will crop in the middle while the deshake filter could manage to crop
 in the right places.

 BTW, in the ffmpeg-devel list, there's a proposal to include a binding for
 vid.stab (https://github.com/georgmartius/vid.stab and
 http://public.hronopik.de/vid.stab/) library.

 The results seems to be superior. Why can't the library be included
 directly in ffmpeg?
