Ogg explicitly supports empty pages with the EOS flag set for
precisely this purpose. At least in theory (i.e. according to spec); I
haven't actually tested this with real applications. So codecs don't
need zero-length packets to tag this case. I'm not sure whether zero
length packets would work, but I see no obvious reason why they
couldn't; I think they probably do.
