VLCJ

A commonly used third-party solution uses the open source VLC Media Player program ,
connecting it to a Java Canvas to display video. Of course, in addition to downloading vlcj ,
you must download and install VLC itself. That is outside the scope of this topic, and is quite
platform-dependent.

This project depends on JNA, an unsupported com.sun package. You use this to tell VLCJ
where VLC is installed; this is one of the first statements in the MyVideoCanvas constructor
in Example 12-8 . Next, you must create an EmbeddedMediaPlayerComponent , call its
getMediaPlayer() method, and tell the resulting player object to prepareMedia() ,
parseMedia() , and play() . These steps are shown in the context of a full example in
Example 12-8 . The URL is supplied on the command line, and can be a local file, a remote
streaming video, or anything else that the underlying VLC player can handle.

Example 12-8. VlcjVideo.java
public public class class VlcjVideo VlcjVideo extends extends JFrame {

private private static static final final long long serialVersionUID = 1L ;

public public static static void void main ( String [] args ) {

new new VlcjVideo ( args [ 0 ]);

}

public public VlcjVideo ( String url ) {

setTitle ( "VLCJ Video" );
setDefaultCloseOperation ( EXIT_ON_CLOSE );
setSize ( 800 , 600 );
JPanel player = new

new MyVideoPanel ();
add ( player , BorderLayout . CENTER );
pack ();
setVisible ( true true );

(( MyVideoPanel ) player ). play ( url );

}

class class MyVideoPanel MyVideoPanel extends extends JPanel {

private private static static final final long long serialVersionUID = 1L ;

private private File vlcWhere = new new File ( "/usr/local/lib" );

private private EmbeddedMediaPlayer player ;

public public MyVideoPanel () {

NativeLibrary . addSearchPath ( "libvlc" , vlcWhere . getAbsolutePath ());
EmbeddedMediaPlayerComponent videoCanvas =
