android - Exoplayer 不循环播放视频

Question

我在我的 Android 应用程序中使用 Exoplayer 来播放视频和音频文件。根据 Exoplayer developer's guide,为了循环视频/音频，这是你必须做的

MediaSource mediaSource = new ExtractorMediaSource(videoUri, ...);
// Loops the video indefinitely.
LoopingMediaSource loopingSource = new LoopingMediaSource(mediaSource);

所以我在我的Activity的onCreate方法中是这样实现的

    BandwidthMeter bandwidthMeter = new DefaultBandwidthMeter();
    TrackSelection.Factory factory = new AdaptiveTrackSelection.Factory(bandwidthMeter);
    TrackSelector trackSelector = new DefaultTrackSelector(factory);

    simpleExoPlayer = ExoPlayerFactory.newSimpleInstance(this,trackSelector);
    simpleExoPlayer.setPlayWhenReady(true);
    simpleExoPlayerView.setPlayer(simpleExoPlayer);

    // Measures bandwidth during playback. Can be null if not required.
    bandwidthMeter2 = new DefaultBandwidthMeter();

// Produces DataSource instances through which media data is loaded.
    dataSourceFactory = new DefaultDataSourceFactory(this,
      Util.getUserAgent(this, applicationName), bandwidthMeter2);

// Produces Extractor instances for parsing the media data.
    extractorsFactory = new DefaultExtractorsFactory();
    mediaSource = new ExtractorMediaSource(videoUri,dataSourceFactory, extractorsFactory, null, null);

    loopingSource = new LoopingMediaSource(mediaSource);
    simpleExoPlayer.prepare(mediaSource);

但是我的视频文件没有循环播放。它只播放一次。

Answer 1

只需使用player.setRepeatMode(player.REPEAT_MODE_ONE);
