Question

我试图从youtube视频＆amp;将其作为a.mp3保存在工作目录中。我正在使用youtube-dl java包装器，我喜欢这里：https://github.com/sapher/youtubedl-java

虽然从我所知道的，它已正确设置，＆amp;我确实提供了一个有效的目录，我一直得到：

Exception in thread "main" com.sapher.youtubedl.YoutubeDLException: Cannot run program "youtube-dl" (in directory "/Users/stephenogden/workspace/Gary"): error=2, No such file or directory
    at com.sapher.youtubedl.YoutubeDL.execute(YoutubeDL.java:69)
    at TestingFunctions.functionTotest(TestingFunctions.java:43)
    at TestingFunctions.main(TestingFunctions.java:15)

我尝试过移动目标目录，但问题仍然存在。

以下是我正在使用的代码：

import java.io.File;
import java.io.IOException;

import com.sapher.youtubedl.YoutubeDL;
import com.sapher.youtubedl.YoutubeDLException;
import com.sapher.youtubedl.YoutubeDLRequest;
import com.sapher.youtubedl.YoutubeDLResponse;

public class TestingFunctions {

    public static void main(String[] args) throws InterruptedException, YoutubeDLException {
        try {

            functionTotest("https://www.youtube.com/watch?v=DECxluN8OZM");

        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    public static void functionTotest(String url) throws IOException, InterruptedException, YoutubeDLException {

        File a = new File("a.mp3");
        if (a.exists()) {
            a.delete();
        }

        // This is the command to run

        String videoUrl = url;
        String directory = System.getProperty("user.dir");

        YoutubeDLRequest request = new YoutubeDLRequest(videoUrl, directory);

        request.setOption("no-mark-watched");
        request.setOption("ignore-errors");
        request.setOption("no-playlist");
        request.setOption("extract-audio");
        request.setOption("audio-format \"mp3\"");
        request.setOption("output \"a.%(ext)s\"");

        YoutubeDLResponse response = YoutubeDL.execute(request);

        String stdOut = response.getOut();

        System.out.println(stdOut);
        System.out.println("File downloaded!");

    }

}

Answer 1

我明白了。

我不得不补充道：

<a class="page-content-header-item" routerLink="/page1" routerLinkActive="selected">Page 1</a>

Java youtube-dl没有这样的文件或目录
