ms939085.tsip03(en-us,MSDN.10).gif

This is an abstract base class that provides support for a simple transform filter with a single input and a single output.

It is derived from the CUnknown class, and supports the IBaseFilter interface, the IMediaFilter interface, and two pins.

Each pin supports the IPin interface and uses the shared memory transport based on the IMemInputPin interface.

The filter uses classes derived from the CBaseMediaFilter class to support IBaseFilter and IMediaFilter.

The input pin is derived from the CBaseInputPin class, and the output pin is derived from the CBaseOutputPin class.
