Show video to JPanel

Question

I am creating a simple video player but I'm having problem to show the video file to stream in JPanel. I've created and designed a JFrame and put a square size JPanel inside the form.

Here is my codes so far:

package SoundsTrip;

import java.awt.BorderLayout;
import java.awt.Component;
import java.io.IOException;
import java.net.MalformedURLException;
import java.net.URL;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.media.CannotRealizeException;
import javax.media.Manager;
import javax.media.NoPlayerException;
import javax.media.Player;
import javax.swing.JFileChooser;
import javax.swing.JOptionPane;

/**

public class VideoFrame extends javax.swing.JFrame {
    /** Creates new form VideoFrame */
    public VideoFrame() {
        initComponents();
        //this.setExtendedState(VideoFrame.MAXIMIZED_BOTH);
        this.setSize(650, 500);
    }

    /** This method is called from within the constructor to
     * initialize the form.
     * WARNING: Do NOT modify this code. The content of this method is

        getContentPane().setLayout(null);

        getContentPane().add(jPanel1);

        pack();

}

Many thanks to any idea and help I could get here... :)

Answer 1

just try this code :

if(mediaURL != null)
           {
                showVideo(mediaURL) //some error here**
            }

Answer 2

Try to add your Video and Control components to your jPanel1

...
if ( video != null )
 jPanel1.add( video, BorderLayout.CENTER ); //add video component
if ( controls != null )
 jPanel1.add( controls, BorderLayout.SOUTH ); //add controls
...

Answer 3

When testing JMF based projects, be sure to use 'JMF compatible' media as might be obtained at my media page. JMF is very old, and does not support many media types or CODECs used for media made recently.

Answer 4

I would really suggest using vlcj either than JFM and showing video in canvas. vlcj is simple as pie, heres the code to get a video pane.

String path = "/usr/lib"; //path for the vlc libs in linux
NativeLibrary.addSearchPath ( "libvlc", path );
System.setProperty ( "jna.library.path", path );

MediaPlayerFactory factory = new MediaPlayerFactory ();
mediaPlayer = factory.newEmbeddedMediaPlayer ();
mediaPlayer.setRepeat ( false );
mediaPlayer.setEnableKeyInputHandling ( false );
mediaPlayer.setEnableMouseInputHandling ( false );

CanvasVideoSurface videoSurface = factory.newVideoSurface ( canvas );
mediaPlayer.setVideoSurface ( videoSurface );
mediaPlayer.playMedia ( "/media/path/" );
