how to control VLC by java

Question

I want to run a program called VLC in java and control it while running, for example if user clicked on ❚❚ or ►► button, I do a specific suitable action.

I run VLC by this code :

try
{
    Runtime rt = Runtime.getRuntime();
    Process p = rt.exec(VLCProgramAddFile + " udp://@:" + listeningPort);

    OutputStream out = p.getOutputStream();
    InputStream in = p.getInputStream();

    p.waitFor();
    System.out.println("End of VLC");
}
catch (Exception e)
{
    System.out.println("error in running VLC");
}

I have heard about Java bindings, but I don't know how does it work for this job.

Answer 1

You are probably looking for VLCJ, this is a java wrapper for VLC. It allows you to embed VLC media player in a java application, and thus add all your personal controls.

(Do note that for user applications this is fine, but the VLCJ library isn't perfect, you can have several problems pop up.)

EDIT: For my project I've seen memory leaks and issues with long running programs (multiple instances for several hours). Especially the multiple instances doesn't work in combination with some compile options (which are on by default).
