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.
Does 'power' in this case mean cpu usage or something else? How about memory- does a filter chain hold all the intermediate frames or discard them (deallocate the memory) once a particular filter has executed.
(Or point me to a place in the code to look at this; I'm not afraid of reading the code if I know where to start.)
