運行帶有Ant配置的Java應用程序時,出現此異常。Debian Jessie JavaFX MediaPlayer:無法創建播放器
Exception in thread "JavaFX Application Thread" MediaException: UNKNOWN : com.sun.media.jfxmedia.MediaException: Could not create player! : com.sun.media.jfxmedia.MediaException: Could not create player!
這裏是我的代碼:
@Override public void start(Stage stage) {
final Scene scene = new Scene(((Viewer)viewer).getPanel());
Media theme = new Media(getHostServices().getDocumentBase() + "src/sound/theme_bttf.mp3");
new MediaPlayer(theme).play();
}
有沒有人對如何解決這一個idean?
我對Debian的傑西64位與侏儒3.14.1和的Java運行:
java version "1.8.0_74"
Java(TM) SE Runtime Environment (build 1.8.0_74-b02)
Java HotSpot(TM) 64-Bit Server VM (build 25.74-b02, mixed mode)
編輯:
這裏是堆棧跟蹤做ant run
當我得到:

編輯2:
我已經libavcodec56
,libavformat56
和GLIB 2.42.1安裝。
# pkg-config --modversion glib-2.0
2.42.1
