That's what it _should_ do. What it will do is a bit less certain (the
code is not that obvious and I have not checked in detail.

Well, for the case of "stupidly implemented demuxers" I was thinking of
yes (it is 320 kB).
Not for all cases though, but that would be overkill to try to work
"perfectly" in all cases and would be a lot of effort (and rather
unrelated to midentify specifically).
