问题
I am using the Xuggle library to play mp4 videos on a JPanel but video loading is taking 3 sec. or more. Do you have some advice how to play video on JPanel or JLabel in the right way?
Is this a good way to show mp4 video? VideoCodec is a Xuggle Codec. This is working but I have a delay of a few seconds.
public void setVideoName(final String videoName) {
imageAndVideoPanel.removeAll();
final VideoPanel videoPanel = new VideoPanel();
videoPanel.setPreferredSize(Const.Dimensions.VIDEO_SIZE);
videoPanel.setMinimumSize(Const.Dimensions.VIDEO_SIZE);
videoPanel.setMaximumSize(Const.Dimensions.VIDEO_SIZE);
imageAndVideoPanel.add(videoPanel);
new Thread(new Runnable() {
@Override
public void run() {
VideoCodec videoCodec =
new VideoCodec(videoPanel, videoName + TextsDao.getText("videoFilesExtension"));
}
}).start();
}

I found a solution. VLCJ library and EmbeddedMediaPlayer. Code to play video/ image is simple:
public class ExamQuestionsLeftPanel extends JPanel {
private EmbeddedMediaPlayerComponent component;
private EmbeddedMediaPlayer player;
...
public ExamQuestionsLeftPanel() {
setUpPanel();
initializeComponents();
}
private void setUpPanel() {
NativeLibrary.addSearchPath(RuntimeUtil.getLibVlcLibraryName(), "VLCx86");
component = new EmbeddedMediaPlayerComponent();
player = component.getMediaPlayer();
Border emptyBorder = BorderFactory.createEmptyBorder(10, 10, 10, 10);
setLayout(null);
setBackground(Const.Colors.EXAM_BACKGROUND_COLOR);
setAlignmentX(Component.LEFT_ALIGNMENT);
setBorder(emptyBorder);
}
...
public void setImageName(String imageName) {
player.stop();
player.prepareMedia("media" + File.separator + imageName);
player.parseMedia();
player.play();
}
public void setVideoName(final String videoTitle) {
new Thread(new Runnable() {
@Override
public void run() {
player.stop();
player.prepareMedia("media" + File.separator + videoTitle);
player.parseMedia();
player.play();
}
}).start();
}
