CTransInPlaceFilteris 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 CUnknownclass, and supports the IBaseFilterinterface, the IMediaFilterinterface, and two pins. Each pin supports the IPininterface and uses the shared memory transport based on the IMemInputPininterface. The filter uses classes derived from the CBaseMediaFilterclass to support IBaseFilterand IMediaFilter. The input pin is derived from the CBaseInputPinclass, and the output pin is derived from the CBaseOutputPinclass.
Protected Data Members
| m_idTransInPlace | Performance-measuring identifier. |
Member Functions
| Copy | Retrieves a pointer to an identical copy of a media sample. |
| CTransInPlaceFilter | Constructs a CTransInPlaceFilterobject. |
| InputPin | Retrieves a pointer to the input pin associated with the filter. |
| OutputPin | Retrieves a pointer to the output pin associated with the filter. |
Overridable Member Functions
| CheckTransform | Verifies that the media type is supported by input and output pins. |
| CompleteConnect | Reconnects the input or output pin if necessary. |
| DecideBufferSize | Determines the size of the transport buffer. |
| GetMediaType | Returns the media type to be used by the output pin. |
| GetPin | Returns a pin if an index is specified. |
| Receive | Receives the sample, calls the derived class's Transformmember function, and then delivers the sample. |
| RegisterPerfId | Registers a performance measurement identifier (if PERF is defined). |
| Transform | Performs transformation operations in place on the IMediaSampleinterface (pure virtual). |
