Represents an event generated by a Media Foundation object. Use this interface to get information about the event.
To get a pointer to this interface, call IMFMediaEventGenerator::BeginGetEvent or IMFMediaEventGenerator::GetEvent on the event generator.
Inheritance

Methods
The IMFMediaEvent interface has these methods.
| IMFMediaEvent::GetExtendedType Retrieves the extended type of the event. |
| IMFMediaEvent::GetStatus Retrieves an HRESULT that specifies the event status. |
| IMFMediaEvent::GetType Retrieves the event type. The event type indicates what happened to trigger the event. It also defines the meaning of the event value. |
| IMFMediaEvent::GetValue Retrieves the value associated with the event, if any. The value is retrieved as a PROPVARIANT structure. The actual data type and the meaning of the value depend on the event. |
Remarks
If you are implementing an object that generates events, call the MFCreateMediaEvent function to create a new event object.
