It’s not yahoo but rather they are webcam player softwares such as fake webam or webcam simulator. People use such programs to broadcast video from their computers to yahoo webcams.
I think one of them is free. I used it long time ago.
Many times when I open someone’s webcam in yahoo room, its showing video rather than showing the person on the other side. How do these people do that? Does yahoo allow you to do that? If so which version of yahoo allows that?
Thank you for your help.
