使用加密密钥在 exoplayer 中播放加密的 hls
Play encrypted hls in exoplayer using encrypted keys
我正在尝试使用 .m3u8 文件播放加密视频。我将视频存储在 AWS 中并创建了 .ts 文件和主播放列表。 Aws 为我提供了该加密视频文件的一些密钥。现在我必须在 exoplayer 中使用这些键。我试过使用 Aes128DataSource 和 DrmSessionManager 但没有成功。
关键类型是：
Encryption Key: ####################################################################
Encryption Key MD5: ################
Encryption Initialization Vector : #############
下面是我用来播放 hls 视频的代码。它可以流畅地播放视频，没有任何问题。我只需要知道在哪里以及如何使用密钥播放加密视频。
String VIDEO_URL = "https://s3.amazonaws.com/######.###.##/videos/mobiletest/mobilemaster.m3u8";
//Create a default TrackSelector
BandwidthMeter bandwidthMeter = new DefaultBandwidthMeter();
TrackSelection.Factory videoTrackSelectionFactory = new AdaptiveTrackSelection.Factory(bandwidthMeter);
TrackSelector trackSelector = new DefaultTrackSelector(videoTrackSelectionFactory);
// Create a default LoadControl
LoadControl loadControl = new DefaultLoadControl();
//Bis. Create a RenderFactory
RenderersFactory renderersFactory = new DefaultRenderersFactory(this);
//Create the player
player = ExoPlayerFactory.newSimpleInstance(renderersFactory, trackSelector, loadControl);
simpleExoPlayerView = new SimpleExoPlayerView(this);
simpleExoPlayerView = (SimpleExoPlayerView) findViewById(R.id.player_view);
//Set media controller
simpleExoPlayerView.setUseController(true);
simpleExoPlayerView.requestFocus();
// Bind the player to the view.
simpleExoPlayerView.setPlayer(player);
// Set the media source
Uri mp4VideoUri = Uri.parse(VIDEO_URL);
//Measures bandwidth during playback. Can be null if not required.
DefaultBandwidthMeter bandwidthMeterA = new DefaultBandwidthMeter();
//Produces DataSource instances through which media data is loaded.
DefaultDataSourceFactory dataSourceFactory = new DefaultDataSourceFactory(this, Util.getUserAgent(this, "PiwikVideoApp"), bandwidthMeterA);
//Produces Extractor instances for parsing the media data.
ExtractorsFactory extractorsFactory = new DefaultExtractorsFactory();
//FOR LIVE STREAM LINK:
MediaSource videoSource = new HlsMediaSource(mp4VideoUri, dataSourceFactory, 1, null, null);
final MediaSource mediaSource = videoSource;
player.prepare(videoSource);
我已经使用 AWS Elastic Transcoder 加密了视频，使用的是 exoplayer 版本：2.6.0
我找到了解决办法。您需要做的技巧是创建您自己的自定义数据源。您需要创建一个扩展 HttpDataSource.BaseFactory 的 class 并从 DefaultHttpDataSourceFactory 添加一些代码。我知道这听起来很疯狂，但我已经通过这种方式解决了。别担心，我在这里粘贴了该自定义的全部代码 class。

}}
您看到方法 createDataSourceInternal 了吗？我返回一个 DefaultHttpDataSource object 使用 header 密钥和令牌 defaultHttpDataSource.setRequestProperty("your header", "your token"); 初始化。所以现在你的 exoplayer 将使用这个 header 键和令牌值来攻击 URL ，你的服务器端将检查这些值以验证有效请求。您的 hls 播放列表 (.m3u8) 包含指控 URL。 Exoplayer 自动使用此 URL。您需要做的就是告诉玩家使用验证密钥。
这里是您的自定义数据源的使用代码：
//ExoPlayer implementation
//Create a default TrackSelector
BandwidthMeter bandwidthMeter = new DefaultBandwidthMeter();
TrackSelection.Factory videoTrackSelectionFactory = new AdaptiveTrackSelection.Factory(bandwidthMeter);
TrackSelector trackSelector = new DefaultTrackSelector(videoTrackSelectionFactory);
// Create a default LoadControl
LoadControl loadControl = new DefaultLoadControl();
//Bis. Create a RenderFactory
RenderersFactory renderersFactory = new DefaultRenderersFactory(this);
//Create the player
player = ExoPlayerFactory.newSimpleInstance(renderersFactory, trackSelector, loadControl);
simpleExoPlayerView = new SimpleExoPlayerView(this);
simpleExoPlayerView = (SimpleExoPlayerView) findViewById(R.id.player_view);
//Set media controller
simpleExoPlayerView.setUseController(true);
simpleExoPlayerView.requestFocus();
// Bind the player to the view.
simpleExoPlayerView.setPlayer(player);
// Set the media source
Uri mp4VideoUri = Uri.parse(VIDEO_URL);
//DefaultHttpDataSource source = new DefaultHttpDataSource(Util.getUserAgent(this, "appAgent"), null);
//source.setRequestProperty("header", "user token");
//Measures bandwidth during playback. Can be null if not required.
DefaultBandwidthMeter bandwidthMeterA = new DefaultBandwidthMeter();
//DefaultDataSourceFactory o = new DefaultDataSourceFactory(this, null, new DefaultHttpDataSourceFactory(Util.getUserAgent(this, "appAgent"), bandwidthMeterA));
CustomDataSourcesFactory o = new CustomDataSourcesFactory("Exoplayer");
