IDvdInfo2 interface (strmif.h)
[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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.]
The IDvdInfo2 interface reports attributes of a DVD disc or the current state of DVD playback and navigation. The DVD Navigator filter implements this interface. IDvdInfo2 is the companion interface to IDvdControl2 interface. IDvdInfo2 groups the DVD Navigator's "get" methods and IDvdControl2 groups the "set" methods. Together they provide DVD navigation and playback functionality beyond the DVD Annex J specification.
Note The information provided by some of these methods can also be obtained through event notifications sent from the DVD Navigator to the application's message loop. For example, to get the current DVD domain, you can call IDvdInfo2::GetCurrentDomain or you can handle the EC_DVD_DOMAIN_CHANGE event in your application's message loop and extract the new domain from the event's lParam1 parameter.
