Osprey-300 User’s Guide
Both filters and pins may have associated
“Properties”. Properties are control parameters
that can be read from or written to the
component. As a user, you interact with them
as visual “Property Sheets”, or “Property Pages”,
or “Tabs” that are part of a tabbed dialog. If
you are a programmer, you might set properties
directly from the code of your application.
The block labeled “Osprey-300 Device 1” in the
center of the filtergraph is the Osprey capture
filter, and the “Filter Properties” about to be
described are the properties and controls for
that component. On the o300avs cap filter there
are four pins. Two of these pins, Capture and
Preview, have associated user-settable properties
that are described below in the section entitled
“Pin Properties”.
The block labeled “Osprey Crossbar” performs
input selection for the driver. The main Osprey
capture filter has an “Input” property sheet that
performs the same input selection function.
