IMFMediaEvent interface (mfobjects.h)
Represents an event generated by a Media Foundation object. Use this interface to get information about the event.
The IMFMediaEvent interface inherits from IMFAttributes. IMFMediaEvent also has these types of members:
The IMFMediaEvent interface has these methods.
Retrieves the extended type of the event.
Retrieves an HRESULT that specifies the event status.
Retrieves the event type. The event type indicates what happened to trigger the event. It also defines the meaning of the event value.
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.
If you are implementing an object that generates events, call the MFCreateMediaEvent function to create a new event object.
