Handle the Windows camera privacy setting 06/07/2024 article windows 10, uwp csharp medium Windows allows users to grant or deny access to the device's camera in the Windows Settings app, under Privacy & Security -> Camera. Camera access can be disabled for the entire device, for all unpackaged apps, or for individual packaged apps. This article describes the best practices for checking whether your app has access to the camera and handling the case where access is denied by the user.Check for access before initializing the cameraFor packaged apps, you should check to see if your app has camera access before initializing the camera. Use the AppCapability class to determine if your app has access.C#bool cameraCapabilityAccess = false;private void CheckCameraAccessStatus(){ var status = AppCapability.Create("Webcam").CheckAccess(); if (status == AppCapabilityAccessStatus.Allowed) { cameraCapabilityAccess = true; cameraButton.IsEnabled = true; } else { cameraCapabilityAccess = false; cameraButton.IsEnabled = false; }}C++bool cameraCapabilityAccess;void MainWindow::CheckCameraAccessStatus(){ auto status = AppCapability::Create(L"Webcam").CheckAccess(); if (status == AppCapabilityAccessStatus::Allowed) { cameraCapabilityAccess = true; cameraButton().IsEnabled(true); } else { cameraCapabilityAccess = false; cameraButton().IsEnabled(false); }}Handle the access denied errorThe Windows camera capture APIs will return the error E_ACCESSDENIED when apps attempt to access the camera capture device if the user has disabled camera in the camera privacy Settings page. Apps should check for this error when initializing the capture device. If the initialization fails with this error, it is recommended that you direct the user to the camera privacy Settings page and potentially enable access for your app. The camera privacy Settings page can be launched using the URI ms-settings:privacy-webcam.The following example illustrates how to check for E_ACCESSDENIED when calling MediaCapture.InitializeAsync.C#try{ await mediaCapture.InitializeAsync(mediaCaptureInitializationSettings);}catch (System.UnauthorizedAccessException ex){ // E_ACCESSDENIED, 0x80070005 in hexadecimal, -2147024891 in decimal if (ex.HResult == -2147024891) { StatusTextBlock.Text = "Access to the camera has been denied." + "Click the Settings button to check the camera privacy settings"; } return;}...// Launch the camera privacy Settings pageprivate async void LaunchSettingsButton_Click(object sender, RoutedEventArgs e){ bool result = await Windows.System.Launcher.LaunchUriAsync(new Uri("ms-settings:privacy-webcam"));}C++try{ co_await mediaCapture.InitializeAsync(mediaCaptureInitializationSettings);}catch (winrt::hresult_error const& ex){ winrt::hresult hr = ex.code(); if (hr == 0x80070005) { StatusTextBlock().Text(L"Access to the camera has been denied. Click the Settings button to check the camera privacy settings."); } co_return;}The following example illustrates handling the E_ACCESSDENIED error returned from IMFActivate::ActivateObject when initializing an IMFMediaSource for a capture device.SetGUID( MF_DEVSOURCE_ATTRIBUTE_SOURCE_TYPE, MF_DEVSOURCE_ATTRIBUTE_SOURCE_TYPE_VIDCAP_GUID);if (FAILED(hr)){ goto done;}// Enumerate devices.UINT32 count;hr =

MFEnumDeviceSources(pAttributes, &ppDevices, &count);if (FAILED(hr)){ goto done;}if (count == 0){ hr = E_FAIL; goto done;}// Create the media source object.hr = ppDevices[0]->ActivateObject(IID_PPV_ARGS(&pSource));if (FAILED(hr)){ if (hr == E_ACCESSDENIED) { int response = MessageBox(hWnd, L"Access to the camera was denied. Open the camera privacy settings?", L"Error", MB_YESNO); if (response == IDYES) { ShellExecute(NULL, L"open", L"ms-settings:privacy-webcam", L"", L".", SW_SHOWDEFAULT); } } goto done;}">IMFMediaSource* pSource = NULL;IMFAttributes* pAttributes = NULL;IMFActivate** ppDevices = NULL;// Create an attribute store to specify the enumeration parameters.HRESULT hr = MFCreateAttributes(&pAttributes, 1);if (FAILED(hr)){ goto done;}// Source type: video capture deviceshr = pAttributes->SetGUID( MF_DEVSOURCE_ATTRIBUTE_SOURCE_TYPE, MF_DEVSOURCE_ATTRIBUTE_SOURCE_TYPE_VIDCAP_GUID);if (FAILED(hr)){ goto done;}// Enumerate devices.UINT32 count;hr = MFEnumDeviceSources(pAttributes, &ppDevices, &count);if (FAILED(hr)){ goto done;}if (count == 0){ hr = E_FAIL; goto done;}// Create the media source object.hr = ppDevices[0]->ActivateObject(IID_PPV_ARGS(&pSource));if (FAILED(hr)){ if (hr == E_ACCESSDENIED) { int response = MessageBox(hWnd, L"Access to the camera was denied. Open the camera privacy settings?", L"Error", MB_YESNO); if (response == IDYES) { ShellExecute(NULL, L"open", L"ms-settings:privacy-webcam", L"", L".", SW_SHOWDEFAULT); } } goto done;}Implement fallback behaviorApps should implement the previous steps to alert the user detect and alert the user that camera access is restricted due to privacy settings and to direct the user to the camera privacy Settings page to allow them to update their settings. After these steps, the app should retry camera initialization to see if access has been granted. If the user declines to update their settings to allow your app to access to the camera, consider providing alternative functionality. For example, you could disable camera features, switch to a different mode, or display a placeholder image in place of the camera preview.
