IConfigAsfWriter2 Interface
The IConfigAsfWriter2 interface extends the IConfigAsfWriter interface, which configures the WM ASF Writer filter. The ConfigAsfWriter2 interface provides additional methods to support the capabilities introduced in the Windows Media Format 9 Series SDK, such as two-pass encoding and support for interlaced output.
In addition to the methods inherited from IConfigAsfWriter, the IConfigAsfWriter2 interface exposes the following methods.
| Method | Description |
| GetParam | Retrieves the current value of the specified filter configuration parameter. |
| ResetMultiPassState | Resets the filter when a preprocessing encoding pass is canceled before it is completed. |
| SetParam | Sets the value of the specified filter configuration parameter. |
| StreamNumFromPin | Retrieves the stream number associated with the specified input pin. |
