Like the audio player, gstreamer can be used to build a simple video player:

public class VideoPlayer {
    public static void main(String[] args) {
        args = Gst.init("VideoPlayer", args);
        final PlayBin playbin = new PlayBin("VideoPlayer");
        playbin.setInputFile(new File(args[0]));

        SwingUtilities.invokeLater(new Runnable() {

            public void run() {
                VideoComponent videoComponent = new VideoComponent();
                playbin.setVideoSink(videoComponent.getElement());

                JFrame frame = new JFrame("VideoPlayer");
                frame.getContentPane().add(videoComponent, BorderLayout.CENTER);
                frame.setPreferredSize(new Dimension(640, 480));
                frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
                frame.pack();
                frame.setVisible(true);
                playbin.setState(State.PLAYING);
            }
        });
        Gst.main();
        playbin.setState(State.NULL);
    }
}

The first few lines once again, just initialize gstreamer and set up the 
PlayBin to play a file:

        args = Gst.init("VideoPlayer", args);
        final PlayBin playbin = new PlayBin("VideoPlayer");
        playbin.setInputFile(new File(args[0]));

Now we have to create somewhere for the video to be displayed.  All these 
operations must be executed on the Swing event dispatch thread, as swing 
components are being created, and swing is not thread-safe, so wrap it all
using SwingUtilities.

        SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                // Do video setup here ...
            }
        });

First we create the VideoComponent - this is a lightweight swing component that
will display video sent to it.

                VideoComponent videoComponent = new VideoComponent();


Second, we have to hook it into the playbin as the video output.  In 
AudioPlayerTutorial we disabled video output via playbin.setVideoSink(), here
we will use it to enable video output.

                playbin.setVideoSink(videoComponent.getElement());

Now we add the videocomponent to a JFrame for display, and do some basic JFrame 
setup to get the window into a sane state.

                JFrame frame = new JFrame("VideoPlayer");
                frame.getContentPane().add(videoComponent, BorderLayout.CENTER);
                frame.setPreferredSize(new Dimension(640, 480));
                frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
                frame.pack();
                frame.setVisible(true);

Lastly, we set the pipeline playing.

                playbin.setState(State.PLAYING);

At the end of the main method we have the usual gstreamer boilerplate:

        Gst.main();
        playbin.setState(State.NULL);

Whilst that isn't strictly neccessary for GUI gstreamer applications, it keeps
the same pattern as used in the other tutorials for familiarity.
