我正在尝试读取Mp4文件作为学习JavaFX的入门者，但无法使路径正确：
public class Main extends Application {
@Override
public void start(Stage primaryStage){
Player player = new Player("file:/home/dave/Player/src/resources/small.mp4");
，错误是：
Exception in Application start method
Exception in thread "main" java.lang.RuntimeException: Exception in Application start method

Caused by: MediaException: UNKNOWN : com.sun.media.jfxmedia.MediaException: Could not create player! : com.sun.media.jfxmedia.MediaException: Could not create player!
我使用Linux（Ubuntu）与IntelliJ和JDK 8.我确信这很简单。
