Registering a SchemeHandler with IMFMediaEngine

Question

Hi,

I have a an implementation of MediaEngine that I use to play video by directly drawing on a D2D texture. Now I want to play a streaming video over a network using the same.

I've been trying to follow the SimpleCommunication sample from Windows 10 Universal samples github. As I understand, the scheme handler simply hast be registered using MediaExtensionsManager and then when the Source property is set for a MediaElement, it will all come together nicely.

How can I achieve the same behavior with MediaEngine? That is after I register a SchemeHandler, if I call MediaEngine->SetSource(BSTR url) will it work? I tried to write code for this, but it didn't work.

Hope it can help you.

Thanks for the threads. I especially find the last one interesting. It seems he was able to register a scheme handler for IMFMediaEngine, and that's exactly what I want to do.

So if I register a scheme handler, and then call IMFMediaEngine->SetSource(url), will the scheme handler get invoked and set the correct source for MediaEngine?

Yes, I think so.
