I use a windows setup with an external webcam. The video is a greenscreen where I add a other background and an additional object. However, this live-showned video should be an available as webcam for video calls, ....

You can use MATLAB to create your edited live video by using the Image Processing Toolbox and the Computer Vision Toolbox. Here are the general steps to follow:

1. Connect to your webcam: You can use the webcam function in MATLAB to connect to your webcam.
2. Capture live video: You can use the snapshot function to capture a single frame from your webcam, or you can use the preview function to continuously capture live video.
3. Apply image processing techniques: You can use MATLAB functions such as imread, etc to manipulate your video frames.
4. Add the background and additional object: You can use MATLAB to add the background and additional object to your video frames. You can use functions like imreadto read in your background and object images, and then use functions like imfuseor imadd to combine them with your video frames.
5. Save the video: You can use the VideoWriter object in MATLAB to save your edited video frames as a video file.

Once you have created your edited live video in MATLAB, you can then use third-party software, such as OBS Studio or ManyCam, to create a virtual webcam that you can use as a video input for MS Teams, Skype, and other video calling applications.
