DVD Event Notification Codes
[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
This section lists the event notification codes for DVD playback and navigation in DirectShow.
For information about receiving events in DirectShow, see Event Notification in DirectShow.
For other non-DVD event codes, see Event Notification Codes.
