IDvdCmd 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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 IDvdCmd interface waits for DVD commands to start or end.
The DVD Navigator creates synchronization objects that expose this interface. The application can use the object to block the DVD Navigator until the command starts or completes. For more information on using this interface, see Synchronizing DVD Commands. (This topic also discusses other ways to synchronize commands without using synchronization objects.)
