I wouldn't have recommend that anyway, honestly using the parser here
is a whole lot more code than just parsing it manually.
I was only trying to suggest that since the table is already in a
suitable format parsing the strings is not much more effort than only
parsing the ints.

Ok, that's not really a feature but a hack.
The filter will by default adjust the aspect (by adjusting the final
display size), however if the user explicitly said "I want the output
to be x by y pixels" that obviously shouldn't be done.
I have no idea how, if at all, libavfilter handles this.
