Question

我正在尝试将手机媒体播放到ExoPlayer中。我从Environment.getExternalStorageDirectory().getAbsoluteFile();

获取路径

每当我尝试播放媒体时，我都会收到此错误 -

来源错误 com.google.android.exoplayer2.upstream.HttpDataSource $ HttpDataSourceException：无法连接到/storage/emulated/0/Download/big_buck_bunny_720p_1mb.mp4

也

引起：java.net.MalformedURLException：no protocol：/storage/emulated/0/Download/big_buck_bunny_720p_1mb.mp4

我在这里通过Uri MediaSource mediaSource = buildMediaSource(Uri.parse(link));

此方法正在使用Uri

private MediaSource buildMediaSource(Uri uri) {
    DataSource.Factory dataSourceFactory = new 
DefaultHttpDataSourceFactory("ua", BANDWIDTH_METER);
    DashChunkSource.Factory dashChunkSourceFactory = new 
DefaultDashChunkSource.Factory(dataSourceFactory);
    return new DashMediaSource(uri, dataSourceFactory, 
dashChunkSourceFactory, null, null);
}

这就是我获取链接的方式

arrayList1 = video(Environment.getExternalStorageDirectory().getAbsoluteFile());
protected ArrayList<File> video(File file) {
    File[] filename = file.listFiles();
    ArrayList<File>  arrayList2 = new ArrayList<File>();
    try {
        for (File file1 : filename) {
            if (file1.isDirectory()) {
                arrayList2.addAll(video(file1));
            } else {
                if (file1.getName().endsWith(".mp4")) {
                    arrayList2.add(file1);
                }
            }
        }
    }catch (Exception e){
    }
    return arrayList2;
}

使用FileDataSource。以下代码段从资产uri（如file：///android_asset/video.mp4或其他文件uris）创建mp4的MediaSource：

  private MediaSource buildMediaSource(Uri uri) {
    DataSource.Factory dataSourceFactory = new FileDataSourceFactory();
    return new ExtractorMediaSource(uri, dataSourceFactory, 
        new DefaultExtractorsFactory(), null, null);
  }

ExoPlayer：Uri：无法加载本地媒体Android
