|---|---|
| ActivateObject | Creates the object associated with this activation object. |

Hinweise
Typically, the application calls some function that returns an IMFActivate pointer and then passes that pointer to another component. The other component calls ActivateObject at a later time to create the object. In the protected media path (PMP), the IMFActivate pointer might be marshaled to the protected process, so that the object can be created in that process.
