First I have a question. Are there anywhere installation instructions for JVLC under windows?

Second:
I try to open more than one jvlc instance. The problem is, that the player opens every player in a own window and when I open 5 or more players, jvlc generates me less than I expected. Have anyone a idea?

package gui;

public class JVLCMain{

	public static void main (String[] args) {
		JFrame.setDefaultLookAndFeelDecorated( true );
                WorkingFrame wf = new WorkingFrame();
    		wf.setVisible(true);
	}
}

There are issues with JVLC for Windows. I posted the issues and the fixes for the dev team but no response yet.
Check the message in this forum by looking at:
viewtopic.php?t=34775

Hopefully these will be addressed soon.

After I checked out the new SVN Version the vlc player crashed with a Segmentation fault.

Hi,

The issues I menioned were fixed recently and in the build. Support for multiple JInternalFrame instances is not working (video vanishes but sound continues) is being looked at. I am working with a few others to resolve the issue but it looks as if linked to getting invalid windows handles.
We are also working on trying to get the build to work cleanly for the java bindings we have a minor issues with it right now.
1 - Need to add --CLASSPATH="./" to the javac line to find packages
2 - running make a second time causes error about multiple targets related to .po files.

Regards,
-Tony
