If that is the case, and there is no solution, is there some other way to set the video capture device to use shared rather than exclusive mode? The above code sample uses IMFCaptureEngine. Do the above #ifs mean that the definitions for IMFSensorDevice/Group are only available for Windows Store apps? I don’t want to create a windows store app, and I want to stick to a classic win32 app. The above project is a classic win32 project. #if WINAPI_FAMILY_PARTITION(WINAPI_PARTITION_APP | WINAPI_PARTITION_GAMES) #pragma region Application or Games Family When I look at this header file, I find this around line 18670, above the definitions for IMFSensorDevice/IMFSensorGroup: #if (WINVER >= _WIN32_WINNT_WINTHRESHOLD) However, this doesn’t compile, and I am getting the following errors in visual studio (community edition 2019): 1>Capture.cpp(250,11): error C3861: 'MFCreateSensorGroup': identifier not foundġ>Capture.cpp(275,21): error C2027: use of undefined type 'IMFSensorGroup'ġ>C:Program Files (x86)Windows KitsInclude.0.(821): message : see declaration of 'IMFSensorGroup' I then added code to call MFCreateSensorGroup using the sym link, to get an IMFSensorGroup* which would then allow me to get an IMFSensorDevice* on which I could call SetSensorDeviceMode to put the device into shared mode. Since IMFAttributes inherits from IMFActivate I added code to call GetAllocatedString() for MF_DEVSOURCE_ATTRIBUTE_SOURCE_TYPE_VIDCAP_SYMBOLIC_LINK so I can get the device symbolic link. The above sample code enumerates devices using MFEnumDeviceSources, which returns an array of IMFActivate* for the devices. My application does not need to be able to control the camera exclusively, as long as I can read from the camera while other applications are also reading from it, I’m happy. One of my goals is to make my application run simultaneously with other video applications. I am building a video capture application using media foundation and started with this example – 14th September 2021 c++, ms-media-foundation, winapi, windows
