Pointer to the sample's IMediaSample interface.
Returns an HRESULT value. Possible values include those shown in the following table.
|S_FALSE||Do not deliver this sample.|
The derived class must implement this method. Transform the sample data in place. If the filter is using two allocators, it copies the data from the input sample to a new sample, and passes the copy to this method.
If the filter should not deliver this sample (for example, to support quality control), the method should return S_FALSE.
