播放某些 mp3 文件时 JavaFX 抛出 ERROR_MEDIA_INVALID

Question

尝试通过 JavaFX 媒体播放器播放某些 .mp3 文件时，我不断收到 ERROR_MEDIA_INVALID 错误。之前的谷歌搜索刚刚导致了旧的错误报告，我不确定这是否是一个真正的错误或我错过的东西。

示例:

package sample;

import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.StackPane;
import javafx.scene.media.Media;
import javafx.scene.media.MediaPlayer;
import javafx.stage.Stage;

import java.io.File;

public class Main extends Application {

    @Override
    public void start(Stage primaryStage) throws Exception{

        primaryStage.setTitle("Hello World!");
        Button btn = new Button();
        btn.setText("Say 'Hello World'");
        btn.setOnAction(new EventHandler<ActionEvent>() {

            @Override
            public void handle(ActionEvent event) {

                //change filename as needed
                var file = new File("C:/Users/tgaravaglia/Downloads/test.mp3");

                var media = new Media(file.toURI().toString());
                var player = new MediaPlayer(media);
                player.setOnError(new Runnable()
                {
                    @Override
                    public void run()
                    {
                        //ERROR_MEDIA_INVALID here
                        player.getError().printStackTrace();
                    }
                });
                player.play();
            }
        });

        StackPane root = new StackPane();
        root.getChildren().add(btn);
        primaryStage.setScene(new Scene(root, 300, 250));
        primaryStage.show();
    }


    public static void main(String[] args) {
        launch(args);
    }
}

所以...我想通了。那个糟糕的“mp3”文件实际上是伪装的 .wav 文件。我通过基于云的 wav->mp3 转换器运行它，现在它工作正常。希望这可以帮助将来遇到同样问题的人!
