Sure, we already have "two" lavf demuxers, one quite at the end, that
one could reasonable use a larger buffer or even the open file function.
I didn't mean to imply that MPlayer would by design have any issue with
probe functions that need more data, it just hasn't been necessary so far
to implement something more advanced.
