从命令行运行应用程序时，JavaFX 8视频播放冻结

Question

when I run this JavaFX 8 application (video playback test) from Eclipse IDE, everything is fine. Application run video playback in loop indefinitely. But when I run this application from command line:

java -jar test-javafx8-video-playback-jar-with-dependencies.jar

it just playback for some seconds and then freeze the playback. Here is a application source code: test-javafx8-video-playback

Please advise, thanks.

OK, here is a code snippet that plays video:

private void playBallMixingAnimation() {
    Media media = new Media(KenoKaironMain.getResourceURIFromProperties(KenoKaironMain.BALL_MIXER_URI_KEY));
    MediaPlayer mediaPlayer = new MediaPlayer(media);
    mediaPlayer.setCycleCount(MediaPlayer.INDEFINITE);
    mediaPlayer.setMute(true);
    mediaPlayer.setAutoPlay(true);
    animMediaView.setMediaPlayer(mediaPlayer);
}

As I said, it works in indefinite loop in Eclipse, but not when I start application from command line. Eclipse is using jdk1.8.0_51 and Windows/OSX is using jre1.8.0_51 and I have more than enough RAM for this small application.

Answer 1

Here is what I found out.

It is all about supported media formats. As you might know JavaFX supports this video formats:

1. FLV container with MP3 and VP6

2. MPEG-4 container with either AAC, H.264, or both

Only FLV video file with On2's VP6 encoding will play in indefinitely loop both started from Eclipse IDE or from command line.

MPEG-4 container with either AAC or H.264 will play in indefinitely loop only from Eclipse IDE and will freeze after first loop when started from command line.

This I tested using Oracle FLV sample: http://download.oracle.com/otndocs/products/javafx/oow2010-2.flv and confirmed by using this FLV sample: http://www.mediacollege.com/video-gallery/testclips/20051210-w50s.flv

For the MPEG-4 you can try by your self and make sure that it won't work in indefinitely loop from command line.

My test configuration is: OS X 10.9.5, Java JDK 1.8.0_51, Eclipse Luna (4.4.1) and code snippet I posted above.
