I tried to use AForge builds (http://www.aforgenet.com/) in a wisej application. I think it seems working. 🙂 I had tried this with VWG but it didn’t work. For screen refresh I used a timer. This is not a complete project just an inspiring small test that I wanted to share with public.
I’m afraid that your code is using the camera on the server. When in debug it’s probably the same as the client.
To send the image re stream to the server I’d use the RecordRTC library: https://www.webrtc-experiment.com/RecordRTC/
Lets you record a video either from the browser’s camera or even simply the content of web page.
