I trying to stream my Web Cam from ComputerA to computerB, using VLCj 3.0.1, VLC 2.1.3 here is the code

}
private void send() {
String mrl ="dshow://";
if(mrl.length() > 0) {

String[] parts = streamTo.split(":");
if(parts.length == 2) {
String host = parts[0];
int port = Integer.parseInt(parts[1]);
String[] localOptions = {formatRtpStream(host, port), ":no-sout-rtp-sap", ":no-sout-standard-sap", ":sout-all", ":sout-keep",};
localMediaPlayer.playMedia(mrl, localOptions);
}
else {
JOptionPane.showMessageDialog(frame, "You must specify host:port to stream to.", "Error", JOptionPane.ERROR_MESSAGE);
}
}
else {
JOptionPane.showMessageDialog(frame, "You must specify source media, e.g. v4l2:///dev/video0 on Linux or dshow:// on Windows.", "Error", JOptionPane.ERROR_MESSAGE);
}
}
private void receive() {
String mrl = "192.168.1.2:5555";
remoteMediaPlayer.playMedia("rtp://@" + mrl);
}
private static String formatRtpStream(String serverAddress, int serverPort) {
StringBuilder sb = new StringBuilder(60);
sb.append(":sout=#transcode{vcodec=mp2v,vb=800,acodec=mpga,ab=128,channels=2,samplerate=44100}:duplicate{dst=display,dst=rtp{dst=");
sb.append(serverAddress);
sb.append(",port=");
sb.append(serverPort);
sb.append(",mux=ts}}");
System.out.println(sb.toString());
return sb.toString();
}
}
So my question is:
How Can I detect that the remote streaming was stopped ? Does LibVLC emits any event when that happens.
and Thanks for your help.
