The DoRenderSample method renders a sample.
virtual HRESULT DoRenderSample( IMediaSample *pMediaSample ) PURE;
Pointer to the sample's IMediaSample interface.
Returns an HRESULT value.
The derived class must implement this method. The behavior depends entirely on the type of filter being implemented. A video renderer, for example, would draw the video image contained in the sample.
