Note that this option is global, since a complex filtergraph by its nature
cannot be unambiguously associated with a single stream or file.
+The @option{-lavfi} option is equivalent to @option{-filter_complex}.

A trivial example of a complex filtergraph is the @code{overlay} filter, which
has two video inputs and one video output, containing one video overlaid on top
of the other. Its audio counterpart is the @code{amix} filter.
@example
ffmpeg -filter_complex 'color=c=red' -t 5 out.mkv
@end example
+
+@item -lavfi @var{filtergraph} (@emph{global})
+Define a complex filter graph, i.e. one with arbitrary number of inputs and/or
+outputs. Equivalent to @option{-filter_complex}.

As a special exception, you can use a bitmap subtitle stream as input: it
