Ah yes, you're right.

I wish this could be enforced by the compiler... As I'm working on push 
filters, there are some classes of filters that will always output a 
single picture (converters), and some that may output more (deinterlacer 
and some video filters). Maybe we could have a particular video filter 
type for converters that would make this easier.
