Media Detector (MediaDet)
[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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.]
Note
[Deprecated. This API may be removed from future releases of Windows.]
The Media Detector (MediaDet) object retrieves format information and still frames from file sources. The Media Detector does not require the Filter Graph Manager to function. To create this object, call CoCreateInstance. The class identifier is CLSID_MediaDet.
To read Windows Media™ files, the application must provide a software certificate, also called a key. Register the application as a key provider through the Media Detector's IObjectWithSite interface. For more information, see Unlocking the Windows Media Format SDK.
