Hello !
I am using Java media framework on windows 7.
I am making a program to transfer live audio and video using RTP in Java media framework.
The problem is that JMF registry contains the built-in camera but when i run program it says that video source is not detected when i select it.program exits.

Unfortunately for you, JMF is a totally obsolete and unmaintened library, you probably won't be able to make it work properly on recent hardware.

If I were you, I'd try to use another library, and the java bindings for libVLC would be my choice, as libVLC is widely used and well maintained.

Another idea :

As far as I know, it may be possible to broadcast audio and video only using the vlc program with the right command-line arguments, without coding any java,
