+@item -dump_filtergraph @var{filename} (@emph{global})
+Set the output file name of filter graph for dump.
+
+It is "ASCII" format by default. for Graphviz DOT output format,
+you can convert it to png by GraphViz tool:
+@example
+dot -Tpng dump_fg_filename -o dump_graph.png
+@end example
+
+@item -dump_filtergraph_format @var{format} (@emph{global})
+Set the output format of filter graph for dump. Support format: "DOT", "ASCII".
+
+DOT is the text file format of the suite GraphViz, ASCII is the text file format
+of ASCII style.
