Libavfilter is at least linear in the number of filters for each single
step of the filtering. That means a filter graph with 2000 filters will
take at least 200 times as much power than a graph with 10 filters.
Really a lot more, because larger graphs tend to be deeper too.

This is not unavoidable, this part would be rather easy to optimize.
