com.google.android.exoplayer2.upstream.HttpDataSource$InvalidResponseCodeException：响应代码：404

Question

好的，我将通过 ExoPlayer 播放 YouTube video，方法是使用 Javascript 接口调用播放过程...

问题是，当我尝试使用 ExoPlayer 打开视频时，它确实尝试打开链接而不是没有播放，当我看到 Logcat 时，我得到了错误

E/ExoPlayerImplInternal: Source error.

我尝试将 final 添加到包含视频 URL 的字符串中，就像 here 中的答案所建议的那样，但仍然得到相同的错误

所以，我尝试向上滚动 Logcat，发现 SSL 错误

SSL_connect:error exit in 3RSH_A SSLv3 read server hello A

然后我尝试使用this中的解决方案，但仍然遇到同样的错误

我的代码

ExoPlayer.java

public class ExoPlayer extends AppCompatActivity{
    private PlayerView playerView;
    private SimpleExoPlayer simpleExoPlayer;
    public static String url;
    public Context context;

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.video_player);

        final String video = getIntent().getStringExtra("video");

        iniExoPlayer(video);
    }


    public void iniExoPlayer(String url){
        Log.d("owo",url);
        simpleExoPlayer = ExoPlayerFactory.newSimpleInstance(this);
        playerView = findViewById(R.id.video_player);
        playerView.setPlayer(simpleExoPlayer);

        //#Default Data Source use this
        DataSource.Factory dataSourceFactory = new DefaultHttpDataSourceFactory(Util.getUserAgent(this, "app-name"));
        MediaSource videoSource = new SsMediaSource.Factory(dataSourceFactory).createMediaSource(Uri.parse(url));
            simpleExoPlayer.prepare(videoSource);
            simpleExoPlayer.setPlayWhenReady(true);
         }

这是我的Logcat

检查您的 URL 链接。因为该链接上没有视频

我通过更改网址解决了
