This class implements the output pin of a simple transform filter. It is the class assigned to the m_pOutput data member of the CTransformFilter class.
Typically, you can create objects of a class derived from CTransformFilter without modifying the CTransformOutputPin class.
To override this class and derive a class from CTransformFilter, use the class and then override the CTransformFilter::GetPin member function to create pins of your derived class.
Protected Data Members
| Member | Description |
|---|---|
| m_pTransformFilter | Pointer to the owning CTransformFilter object. |
Public Data Members
| Member | Description |
|---|---|
| m_pPosition | Pointer to a CPosPassThru object that implements the IMediaPosition interface to pass media position commands on to the upstream filter. |
Member Functions
| Member function | Description |
|---|---|
| CTransformOutputPin | Constructs a CTransformOutputPin object. |
| CurrentMediaType | Retrieves the media type currently assigned to the filter. |
Overrideable Member Functions
| Member function | Description |
|---|---|
| BreakConnect | Informs the derived class when the connection is broken. |
| CheckConnect | Informs the derived class when the connection process is starting. |
| CheckMediaType | Determines if the pin can use a specified media type. |
| CompleteConnect | Informs the derived class when the connection process has completed. |
| DecideBufferSize | Determines the number and size of buffers required. |
| GetMediaType | Returns the media type that the output pin uses. |
| SetMediaType | Informs the derived class when the media type is established for the connection. |
Implemented IQualityControl Methods
| Method | Description |
|---|---|
| Notify | Receives a quality-control notification, typically from a downstream filter. This method is inherited from the IQualityControl interface through the CBasePin class. |
Implemented IPin Methods
| Method | Description |
|---|---|
| QueryId | Retrieves an identifier for the pin. |
Implemented INonDelegatingUnknown Methods
| Method | Description |
|---|---|
| NonDelegatingQueryInterface | Returns an interface and increments the reference count. |
Requirements
