Using the Source Reader in Asynchronous Mode

[Gawson]

As shown in MSDN https://msdn.microsoft.com/en-us/library/windows/desktop/gg583871(v=vs.85).aspx SourceReader is able to asynchonous sample read. How can it be achieved in Sharpdx?

1. How to create and set async callback? There is no IMFSourceReaderCallback interface, only the SourceReaderCallback class but when class inherits it you cant override methods and base class requires native pointer (to what?).

2. Following docs in MSD all out parameters in ReadSample method of SourceReader should be null to use callback and async mode but out parameters can't be set null. Is this inconsistent mapping? In MediaFoundation .Net there is separate ReadSampleAsync method.

Both of problems seems like potetnial bugs.
Am I missing something?

I don't remember exactly why it was not mapped, buy many things from MF have not been mapped, typically callback interfaces. Also, I think that I have avoided implementing any async from DirectX methods, as it is easier to implement them in C# (unless the implementation is doing some special things when using Async native mode)
