In this case, it is right. However, "movie" source doesn't have
duration option, and if set with loop=1, it will produce frames
forever. So to stop it, we would need to overlay it over something
having finite duration, e.g. "color" source, because "overlay" filter
has policy to return EOF when some input indicates EOF.
