使用Exoplayer2时，如何始终使用默认图稿(即使音频中嵌入了图稿？)

implementation 'com.google.android.exoplayer:exoplayer-core:2.X.X'
implementation 'com.google.android.exoplayer:exoplayer-ui:2.X.X'

<com.google.android.exoplayer2.ui.SimpleExoPlayerView
    android:id="@+id/exo_player_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

// 在Activity或Fragment中声明以下变量
private SimpleExoPlayer player;
private SimpleExoPlayerView playerView;

// 在onCreate方法中初始化ExoPlayer和设置默认图稿
playerView = findViewById(R.id.exo_player_view);
player = ExoPlayerFactory.newSimpleInstance(this);
playerView.setPlayer(player);

// 创建一个默认的TrackSelector
TrackSelector trackSelector = new DefaultTrackSelector();

// 将TrackSelector分配给ExoPlayer
player.setTrackSelector(trackSelector);

// 创建一个默认的LoadControl
LoadControl loadControl = new DefaultLoadControl();

// 将LoadControl分配给ExoPlayer
player.setLoadControl(loadControl);

// 创建一个默认的RenderersFactory
RenderersFactory renderersFactory = new DefaultRenderersFactory(this);

// 将RenderersFactory分配给ExoPlayer
player.setRenderersFactory(renderersFactory);

// 创建一个默认的MediaSource
MediaSource mediaSource = new ExtractorMediaSource.Factory(dataSourceFactory)
    .createMediaSource(Uri.parse("your_media_url_here"));

// 将MediaSource分配给ExoPlayer
player.prepare(mediaSource);

// 开始播放
player.setPlayWhenReady(true);
