IMFDXGIBuffer interface not found

IMFDXGIBuffer interface is missing on Windows Server 2016.
I have installed "Media Foundation" feature, but the problem still exists. Also latest DirectX is installed..

What could cause this issue?

The Media Foundation APIs are part of the Windows SDK. To develop a Media Foundation application, install the latest version of the Windows SDK. Have you installed Windows SDK?

Yes, SDK is installed and project is built with success. Note that this same project works fine on Windows 10.
On Server 2016 app crash when try to QueryInterfce ->QueryInterface(&bufferDxgi).

Also I got errors way before this QueryInterfce ,after this code:

await mediaCapture.InitializeAsync(new MediaCaptureInitializationSettings { VideoDeviceId = deviceId, StreamingCaptureMode = StreamingCaptureMode.Video // No audio });

Errors in console:

Exception thrown at 0x7440C562 (KernelBase.dll) in TestControl.exe: WinRT originate error - 0xC00D36B3 : 'The stream number provided was invalid.'.

Thanks for confirmation. Can you use this official sample with the following edition to see if it reproduces the same issue? If yes, I can use this sample to test on Windows Server 2016 for reproducing. After this line: hr = CopyBuffer->QueryInterface(__uuidof(IDXGISurface), (void **)&CopySurface); add the following code piece:

IMFMediaBuffer* mediaBuf; hr = MFCreateDXGISurfaceBuffer(__uuidof(ID3D11Texture2D), CopySurface, 0, TRUE, &mediaBuf); IMFDXGIBuffer* dxgiBuf; hr = mediaBuf->QueryInterface(__uuidof(IMFDXGIBuffer), (void**)& dxgiBuf);

@iz111 I can query IMFDXGIBuffer interface successfully with the official sample mentioned in my last comment on Windows Server 2016 Standard (Version 1607 OS Build 14393.3181)

Thanks for response. The official sample with this sample code works properly wih no errors.
I'm trying to use this to load 4K camera preview in WinForms using WPF hosting.

Glad to hear it works for you. Feel free ask new questions if you have any issue about using other Win32 APIs. For WinForms programming issue you can get more professional support at Microsoft Q&A - windows-forms. For WPF at Mircosoft Q&A - windows-wpf.

Hello,

IMFDXGIBuffer interface not found

Make sure you create this interface in right way like this: first create the DXGIsurface. Then call MFCreateDXGISurfaceBuffer. MFCreateDXGISurfaceBuffer returns IMFMediaBuffer object support IMFDXGIBuffer interface.

You can use this official sample: DXGIDesktopDuplication with the following edition to check if you can query IMFDXGIBuffer successfully:

After this line: hr = CopyBuffer->QueryInterface(__uuidof(IDXGISurface), (void **)&CopySurface); add the following code piece:

IMFMediaBuffer* mediaBuf; hr = MFCreateDXGISurfaceBuffer(__uuidof(ID3D11Texture2D), CopySurface, 0, TRUE, &mediaBuf); IMFDXGIBuffer* dxgiBuf; hr = mediaBuf->QueryInterface(__uuidof(IMFDXGIBuffer), (void**)& dxgiBuf);

Thank you!
