Hinweise
This interface is exposed by media-type handlers.
- For media sources, get the media-type handler from the stream descriptor by calling IMFStreamDescriptor::GetMediaTypeHandler.
- For media sinks, get the media-type handler by calling IMFStreamSink::GetMediaTypeHandler.
If you are implementing a custom media source or media sink, you can create a simple media-type handler by calling MFCreateSimpleTypeHandler, or you can provide your own implementation.
This interface is available on the following platforms if the Windows Media Format 11 SDK redistributable components are installed:
- Windows XP mit Service Pack 2 (SP2) und höher.
- Windows XP Media Center Edition 2005 with KB900325 (Windows XP Media Center Edition 2005) and KB925766 (Oktober 2006 Updaterollup für Windows XP Media Center Edition) installed.
