Usage

With Swing

JAVI integrates seamlessly with Swing through the SwingMediaPanel.

File videoFile = ...
// Open a media instance
Media media = MediaFactory.open(videoFile);

// Load media into panel
SwingMediaPanel videoPanel = new SwingMediaPanel(media);

// Select a video & audio stream to play
videoPanel.setVideoStream(media.videoStreams().get(0));
videoPanel.setAudioStream(media.audioStreams().get(0));

// Create a simple panel to house player
JFrame display = new JFrame("JAVI Test");
display.setLayout(new BorderLayout());
display.add(BorderLayout.CENTER, videoPanel);
display.setSize(640, 480);
display.setVisible(true);

// Start video playback
videoPanel.start();

It's that simple!

With your graphics library of choice

SwingMediaPanel handles a bit of the backend, but if you wish to use a graphics library other than Swing, you'll need to utilise MediaStream.

File videoFile = ...
// Open a media instance
Media media = MediaFactory.open(videoFile);

MediaStream stream = media
        .stream() // Begin setup
        // Specify audio handler; may be left out.
        .audio(new MediaHandler<byte[]>() {
            @Override
            public void handle(byte[] buffer) {
                // buffer is in signed 16-bit little-endian PCM format.
                // frequency & channel count can be obtained from a AudioStream instance.
            }
        })
        // Specify video handler; may be left out.
        .video(new MediaHandler<BufferedImage>() {
            @Override
            public void handle(BufferedImage buffer, long duration) {
                // buffer contains frame data
                // duration is the duration this frame should elapse before this frame;
                // taking into consideration audio-video sync.
            }

            @Override
            public void end() {
                // Notification on stream end
            }
        })
        // Create stream.
        // At least one handler must be specified, or an exception is thrown.
        .create();

// Now we can start the stream synchronously
stream.run();
// Or asynchronously
new Thread(stream).start();

As a Maven Dependency

The easiest way to get started with JAVI is with it as a dependency in your Maven project. You must first add our Maven repository, then add JAVI as a dependency.

<dependencies>
    <dependency>
        <groupId>tk.ivybits.javi</groupId>
        <artifactId>javi</artifactId>
        <version>1.0-SNAPSHOT</version>
    </dependency>
</dependencies>

<repositories>
    <repository>
        <id>IvyBits</id>
        <url>http://maven.ivybits.tk</url>
    </repository>
</repositories>

Coding and Pull Requests Guidelines

• We follow the Oracle coding conventions.
  • 4 spaces; not tabs.
  • No trailing whitespaces.
  • No 80 column limit.
• Pull requests should be tested before submission.
• Any additions in API should be properly documented.
• Avoid unnecessary class coupling where possible.
• Don't include IDE-specific files, class files, jar files, and whatnot; that is what the .gitignore is for!
