virtual HRESULT Transform(
IMediaSample* pSample
) PURE;
Parameters

Return Values
Returns an HRESULT value that depends on the implementation. HRESULT can be one of the following standard constants, or other values not listed.

Remarks
You must supply this member function in the derived class to perform the actual work of your filter. This member function is called by CTransInPlaceFilter::Receive before passing the sample on to the downstream filter. Transform can return S_FALSE to indicate that the sample should not be delivered downstream.
