At the moment i am being able to see my own webcam in unity3d as a texture using this simple tutorial http://www.ikriz.nl/2011/12/23/unity-video-remake Now i want to know that how can i see someone's else webcam in unity 3d? can any body give me some pointers?
To help any one who would find this helpful in future, i have done this by using a flash client that takes the live stream and send it to a local server which was written in .Net. and that .net server then sends the stream to our script which was running in unity3D. and that script was placed on any plane in your model , so showing you the received stream. It was a bit laggy but it was working :)
