Could it be possible to keep the already spawned outputs as long as we don't
know what kind of data we have in the new stream.
That way we won't introduce any delays if the outputs are already loaded and
don't need to be spawned.
And if we need to respawn a new output then we would use a synchronisation
mechanism to be sure that all the needed outputs are ready before decoding
anything (and thus introduce a delay for the end-user).
It looks like a good compromise to me (although I don't know if it's possible
or easy enough to do).
