无法使用 Javafx MediaPlayer 播放 wav 或 mp3 文件。也无法使用本机 java 库播放 wav 文件

Can't play wav or mp3 files with Javafx MediaPlayer. Also can't play wav files with the native java library

我有一个 java 项目,我必须制作一个可以播放 wav 或 mp3 文件的音乐播放器。但是,我无法使用 Javafx 库或本机 java 库播放我的 wav 或 mp3 文件。我已经检查并确保我用来测试的 wav 和 mp3 文件没有损坏。我正在使用 Javafx 17.0.2 和 JDK 11.

Javafx

的迷你可复制示例

JavaFxMp3WavPlayer

package mediaplayerjavafx;

import java.io.File;
import java.io.IOException;
import java.net.MalformedURLException;
import javafx.application.Application;
import javafx.event.Event;
import javafx.event.EventHandler;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.media.Media;
import javafx.scene.media.MediaPlayer;
import javafx.stage.Stage;

public class JavaFxMp3WavPlayer extends Application {

    public static void main(String[] args) throws MalformedURLException, IOException {
        launch(args);

    }

    @Override
    public void start(Stage stage) throws Exception {
        stage.setTitle("My");
        Button button = new Button("My Button");
        Scene scene = new Scene(button, 200, 100);
        stage.setScene(scene);
        stage.show();
        File file = new File("C:\Users\John Doe\MotisHarmony\accounts\yourLieInApril\downloadedMusic\Mp3Test.mp3");
        String path = file.toURI().toASCIIString();
        Media media = new Media(path);
        MediaPlayer mediaPlayer = new MediaPlayer(media);
        button.setOnAction(new EventHandler() {
            @Override
            public void handle(Event arg0) {
                runMusicPlayer(mediaPlayer);
            }
        });
    }

    public void runMusicPlayer(MediaPlayer mediaPlayer) {
        mediaPlayer.play();
    }
}

模块信息

module MotisHarmony {
    requires javafx.swt;
    requires javafx.base;
    requires javafx.controls;
    requires javafx.fxml;
    requires javafx.graphics;
    requires javafx.media;
    requires javafx.swing;
    requires javafx.web;
    exports mediaplayerjavafx;
    opens mediaplayerjavafx to javafx.graphics;
}

产生错误

所以在这不起作用之后,我尝试使用本机 Java 库。

使用本机 Java 库的迷你可复制示例

JavaWavPlayer

import java.io.File;
import java.io.IOException;
import javax.sound.sampled.AudioFormat;
import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.Clip;
import javax.sound.sampled.DataLine;
import javax.sound.sampled.LineUnavailableException;
import javax.sound.sampled.UnsupportedAudioFileException;

public class JavaWavPlayer {

    /**
     * @param args the command line arguments
     */
    public static Clip clip;

    public static void main(String[] args) throws UnsupportedAudioFileException, LineUnavailableException, IOException {
        File yourFile = new File("C:\Users\John Doe\MotisHarmony\accounts\yourLieInApril\downloadedMusic\WavTest.wav");
        AudioInputStream stream;
        AudioFormat format;
        DataLine.Info info;
        stream = AudioSystem.getAudioInputStream(yourFile);
        format = stream.getFormat();
        info = new DataLine.Info(Clip.class, format);
        clip = (Clip) AudioSystem.getLine(info);
        clip.open(stream);
        clip.start();
    }

}

产生错误

I am using JDK 11 and Javafx 17.0.2

System Type: 64-bit operating system, x64-based processor

Processor: Intel(R) Core(TM) i7-7700HQ CPU @ 2.80GHz 2.81 GHz

Windows Edition: Windows 10 Home

我无法重现您的问题。

你的问题是环境问题,具体是什么我不能说。

我建议在 idea 中创建一个新项目并按照我所做的相同步骤进行操作,只要文件路径正确,它就应该可以工作。

这些是我为允许媒体使用您的示例应用程序播放而遵循的步骤:

  1. 在 Windows 11.

    使用 OpenJDK 17.0.2 和 JavaFX 17.0.2 创建了一个 new JavaFX project in Idea
  2. Copy-and-pasted将您的 JavaFX 示例代码放入新项目中。

  3. 按照说明将媒体处理添加到项目中:

  4. 已下载您的 mp3 和 wav 文件。

  5. 依次设置文件路径。

  6. 运行 应用程序并点击每个文件的播放按钮。

MP3 和 WAV 文件都可以正常播放。

你四月的谎言很好,我会努力学习的
