Much more useful version attached.

Simple demo demonstrating functionality currently missing in lavfi:

lavfi.log(0, "Lavfi script example", lavfi.script_name, lavfi.frame_count(0));
if (lavfi.frame_count(0) >= 50) then
    lavfi.filter({"aa"}, "vflip", nil, {"a"})
    lavfi.filter({"bb"}, "hflip", nil, {"b"})
else
    lavfi.filter({"aa"}, "negate", nil, {"a"})
    lavfi.filter({"bb"}, "vflip",  nil, {"b"})
end

lavfi.filter({"a", "b"}, "hstack", "2", {"out0"});
