Is the IMFMediaEngine support load customer source from Windows::Media::MediaExtensionManager RegisterSchemeHandler?

Question

Currently, I want to use a customer media source for IMFMediaEngine, I use Windows::Media::MediaExtensionManager::RegisterSchemeHandler to register a scheme. but after IMFMediaEngine::SetSource then invoke IMFMediaEngine::Load, the IMFMediaEngine can't load the customer source I have registerd in Windows::Media::MediaExtensionManager::RegisterSchemeHandler.  

]I found there has a IMFMediaEngineExtension interface which can load customer source, but this interface need inhert by my customer source and before create IMFMediaEngine, the pointer of this interface should pass to MF_MEDIA_ENGINE_EXTESION attribute. 

Is there any way can get the customer source in Windows::Media::MediaExtensionManager, or the Windows::Media::MediaExtensionManager only for MediaElement.

Thanks.

It's not clear exactly what you mean by a custom source, but I suspect you will need to implement IMFMediaEngineExtension. See the Media extensions sample for an example.

Thanks Rob,

The custom source is a IMFMediaSource interface impelment by myself.

The Media extension sample work fine with Windows::UI::Xaml::Controls::MediaElement, But the source register in Windows::Media::MediaExtensionManager can't be found by IMFMediaEngine(I modfiy the sample base on Media engine native C++ video playback sample ). So I suspect that source register in Windows::Media::MediaExtensionManager only can be found by Windows::UI::Xaml::Controls::MediaElement. The IMFMediaEngine only can use IMFMediaEngineExtension to find a custom source.

Thanks.
