Filters have two interrelated purposes:

They allow applications to enumerate and list DirectShow video capture and preview pins or
streams (each with different settings) as named entries in their video device select list. You
can set up the driver to show 1 to 10 filters per device. Each filter has one preview pin and
one capture pin. Standard applications can access a particular filter without any custom
programming specialized for Osprey devices.

Each filter has independent settings for cropping, default output size, logos, and captions
that can be stored between sessions. Compared to the previous pin-based method, there
are no requirements for a particular startup order, in order to associate settings with
instantiations.
