NoPlayerException,
CannotRealizeException {
audioPlayer = Manager.createRealizedPlayer(url);
}
public SimpleAudioPlayer(File file) throws IOException,
NoPlayerException,
CannotRealizeException {
this(file.toURL());
}

public void play() {
audioPlayer.start();
System.out.println("playing");}

I'm working with Java Media Framework and I've noticed some problem with
closing processor.
I have some application that gets video  stream from webcam and send it
over LAN (using RTPMenager) to other PCs.
When I try to close  transmission, just after transmission get started,
the transmission closed properly. But when I closed transmission after a
while it seems that aplcation get stucked in processor.close function !
Does anyone have some experience with this ?
Any suggestion ?
