IMFMediaEventGenerator interface (mfobjects.h)

Retrieves events from any Media Foundation object that generates events.

Inheritance

The IMFMediaEventGenerator interface inherits from the IUnknown interface. IMFMediaEventGenerator also has these types of members:

Methods

The IMFMediaEventGenerator interface has these methods.

 
IMFMediaEventGenerator::BeginGetEvent

Begins an asynchronous request for the next event in the queue.
IMFMediaEventGenerator::EndGetEvent

Completes an asynchronous request for the next event in the queue.
IMFMediaEventGenerator::GetEvent

Retrieves the next event in the queue. This method is synchronous.
IMFMediaEventGenerator::QueueEvent

Puts a new event in the object's queue.

Remarks

An object that supports this interface maintains a queue of events. The client of the object can retrieve the events either synchronously or asynchronously. The synchronous method is GetEvent. The asynchronous methods are BeginGetEvent and EndGetEvent.
