Microsoft DirectX 9.0

IFilterInfo Object

The IFilterInfo object manages information about a filter. This object is a wrapper for a DirectShow filter object, because DirectShow filters are not Automation-compatible.


Include a reference in your project to "ActiveMovie control type library" (Quartz.dll).
