Pass the source unchanged to the output.
@section slicify
Pass the images of input video on to next video filter as multiple
slices.
@example
./ffmpeg -i in.avi -vfilters "slicify=32" out.avi
@end example
The filter accepts the slice height as parameter. If the parameter is
not specified it will use the default value of 16.
Adding this in the beginning of filter chains should make filtering
faster due to better use of the memory cache.
@section vflip
Flip the input video vertically.
