无法使用exoPlayer 2.11播放MKV Matroska视频

我在Github上制作了一个示例项目，该项目可以正确处理您的文件。您可以在下面的链接中进行检查和测试：

Sample

如果您只想使用项目中的代码，请先从设备或仿真器中卸载以前安装的应用程序，然后运行新的应用程序。

以下是项目的基本代码：

MainActiviy.java

public class MainActivity extends AppCompatActivity {    private PlayerView playerView;    private SimpleExoPlayer player;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        playerView = findViewById(R.id.player_view);    }    @Override    protected void onStart() {        super.onStart();        player = ExoPlayerFactory.newSimpleInstance(this, new DefaultTrackSelector());        playerView.setPlayer(player);        DataSource.Factory dataSourceFactory = new DefaultDataSourceFactory(     this,     Util.getUserAgent(this, getString(R.string.app_name)));        ProgressiveMediaSource mediaSource = new ProgressiveMediaSource.Factory(dataSourceFactory)     .createMediaSource(Uri.parse("file:///android_asset/jellyfish-3-mbps-hd-h264.mkv"));        player.prepare(mediaSource);        player.setPlayWhenReady(true);    }    @Override    protected void onStop() {        super.onStop();        playerView.setPlayer(null);        player.release();    }}

activity_main.xml

<?xml version="1.0" encoding="utf-8"?><androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:app="http://schemas.android.com/apk/res-auto"    android:layout_width="match_parent"    android:layout_height="match_parent">    <com.google.android.exoplayer2.ui.PlayerView        android:id="@+id/player_view"        android:layout_width="match_parent"        android:layout_height="match_parent"        android:background="#000000"        app:resize_mode="fill" /></androidx.constraintlayout.widget.ConstraintLayout>

另外，您需要将以下依赖项添加到应用程序级别的Gradle文件中：

implementation 'com.google.android.exoplayer:exoplayer-core:2.11.7'implementation 'com.google.android.exoplayer:exoplayer-ui:2.11.7'

我将视频文件放在
