Some man pagers do not reflow the text/graphs on resize
and the graphs did not fit the traditional 80cols due

an additional step between decoding and encoding:
@example
- _________ __________ ______________
-| | simple | | | |
-| decoded | fltrgrph | filtered | encoder | encoded data |
-| frames | ----------> | frames | ---------> | packets |
-|_________| |__________| |______________|
+ _________ ______________
+| | | |
+| decoded | | encoded data |
+| frames |\ /| packets |
+|_________| \ / |______________|
+ \ __________ /
+ simple \ | | / encoder
+ filtergraph \| filtered |/
+ | frames |
