Question

0.00/5 (No votes)

See more:

we have build an application on winui3. using MediaCapture we are fetching the camera stream. we are enabled SharingMode as "SharedReadOnly" we expect other applications like teams can access the same stream. It was working fine. No we are facing issue like teams grabbing the camera in exclusive mode.

C#

var settings = new MediaCaptureInitializationSettings
    {
        SourceGroup = mediaFrameGroup,
        SharingMode = MediaCaptureSharingMode.SharedReadOnly
        StreamingCaptureMode = StreamingCaptureMode.Video,
        MemoryPreference = MediaCaptureMemoryPreference.Cpu,
        MediaCategory = MediaCategory.Communications
    };

How can use shareReadOnly?

Teams accessing camera feed as exclusive mode it should not happen.

winui-3

What I have tried:

Tried by upgrading

Microsoft.Windows.SDK.BuildTools

and

Microsoft.WindowsAppSDK

to latest version in windows 11 but not affected

I suspect the problem isn't your code, but rather it's Teams. As a test, try running your application and Teams running in a web browser. If your app works when Teams is using browser access to get to the camera, then the problem is with Teams and, unfortunately, there's not a lot you're going to be able to do about that other than raise a report with Microsoft.
