Below is the output listing after launching VLC.exe from within a standalone Java application using the command
"C:/Program Files/VideoLAN/VLC/vlc.exe" -vvv --extraintf=logger
In summary:
We launch our Java app (either via Eclipse IDE or JNLP) and click a button to exec() the VLC command. The vlc process is created and appears in the TaskManager but the UI doesnt appear until we close our application.
The listing below is identical (except for thread IDs and other numbers) to the output from the same command issued in a command prompt which does show the UI, so I'm not sure this will give you any clues.
This same behaviour is shown on three separate PCs, two WinXPs in the work environment and one home PC running Vista.

I'd be interested if anyone else is seeing this? Here is a sample app that produces the effect. The app doesn't appear until the dialog is cleared and the program quits.
Code: Select all
public static void main(String[] args)
{
try
{
Runtime.getRuntime().exec("C:/Program Files/VideoLAN/VLC/vlc.exe");
JOptionPane.showConfirmDialog(null, "Quit Program", "Test", JOptionPane.OK_OPTION);
}
catch (IOException e){e.printStackTrace();}
}
