>From a (very) quick look at the source, I don't think this 
is correct but it doesn't matter because defaults may 
change. Note that you should not assume FFmpeg plus 
external library behaves like external library plus raw 
input. This may be true for some cases but you must not 
rely on it and I don't think there is a bug if the 
library behaves differently (by default) with or without
