You can access a file by reading it the usual way (see removelogo for
an example). On the other hand if you want to do a multi-pass
filtering this may be more difficult, since a filter is not supposed
to read a file that way (unless you want to duplicate the movie source
functionality in the filter, which I would reject).

So the question is: what do you exactly want to achieve? Note: asking
on IRC may be faster.
