Unable to preview camera

[luiey]

I want to create a preview webcam and get the snapshoot of the image. But I cannot initialize the camera. I have built-in notebook web camera and logitech portable web camera. As image below, I have also download sample AForge program to test but it failed. BUT, when using Win10 Camera app, it can show both camera. Any help/clarification to handle this?

I would suggest debugging with the source code. See how far camera configuration gets, if you get any video frames, etc. Also make sure cameras are not in use by another application.

Faced with a similar problem. How do I know that the camera is not used by another application?
