- Transfer
Webcam support was the most anticipated innovation and was not new to anyone. It is relatively easy to activate this feature. The following example demonstrates a simple UI with code that connects a webcam. This post does not affect working with multiple webcams, however, by calling CaptureDeviceConfiguration.GetAvailableVideoCaptureDevices , you get a list of all available webcams.

Add a button click event. The logic looks something like this:
The next step is to launch the application. You will see a blank screen with a button, after clicking on which, a request window will open to allow the program to use the webcam and microphone. Of course, click "Yes";).

Add a button click event. The logic looks something like this:
- Get the handler of your video capture device using CaptureDeviceConfiguration .
- Request access to the CaptureDeviceConfiguration.RequestDeviceAccess () device .
- If the user has confirmed access, create a CaptureSource object and then set VideoCaptureDevice to the selected webcam.
- Create VideoBrush .
- Set the source of the video brush ( VideoBrush ).
- Launch a webcam.
- Draw a Rectangle (you can use any objects that accept brushes)
