ExoPlayer不显示资产视频

Question

嘿，伙计们，我一直试图在exoPlayer中显示视频，因为2天，但没有任何进展，请指导我做错了什么。谢谢提前。

这是我对create函数的代码调用。

 private void initializePlayer() {
    simpleExoPlayerView = findViewById(R.id.exoPlayerView);
    simpleExoPlayerView.requestFocus();
    DataSpec dataSpec = new DataSpec(Uri.parse("assets:///splash_video.mp4"));
    player = ExoPlayerFactory.newSimpleInstance(this, new DefaultTrackSelector(), new DefaultLoadControl());
    simpleExoPlayerView.setPlayer(player);
    final AssetDataSource assetDataSource = new AssetDataSource(this);
    try {
        assetDataSource.open(dataSpec);
        DataSource.Factory factory = new DataSource.Factory() {
            @Override
            public DataSource createDataSource() {
                return assetDataSource;
            }
        };
        player.setPlayWhenReady(true);
        DefaultExtractorsFactory defaultExtractorsFactory = new DefaultExtractorsFactory();
        MediaSource audioSource = new HlsMediaSource(assetDataSource.getUri(), factory, new Handler(), null);
        Log.e(TAG, assetDataSource.getUri().getPath());
        player.prepare(audioSource);
    } catch (AssetDataSource.AssetDataSourceException e) {
        e.printStackTrace();
    }
}

我的图书馆版本是

compile 'com.google.android.exoplayer:exoplayer:r2.5.4'

DefaultDataSourceFactory支持为资产URI创建数据源。要玩MP4资产，请为玩家准备一个extractoremiaSource，您可以这样创建：

new ExtractorMediaSource(
    Uri.parse("asset://splash_video.mp4"),
    new DefaultDataSourceFactory(context, userAgent),
    new DefaultExtractorsFactory(),
    null,
    null);
