IMediaEventEx interface

The IMediaEventEx interface inherits the IMediaEvent interface, which contains methods for retrieving event notifications and for overriding the filter graph's default handling of events. IMediaEventEx adds methods that enable an application window to receive messages when events occur.

The Filter Graph Manager implements this interface.

For more information about event notification, see Event Notification in DirectShow. For a list of system-defined event notifications, see Event Notification Codes.
