ExoPlayer version 2.12.x to 2.15.x ​

1. Require ​

Some general requirement is here

Prerequisite

  • Add a dependency in the build.gradle file of your app module. The following will add a dependency to the full library:
java
implementation 'com.google.android.exoplayer:exoplayer:2.12.0'
  // If you don't use feature license encrypt, please comment line below
  implementation 'com.sigma.packer:2.12.x:1.0.3'

2. Integrate MediaDrmCallback ​

Please see at MediaCallback

3. Create PlayerActivity using WidevineMediaDrmCallback ​

If you have experience with Exoplayer, then please avoid this chapter.

3.1. Create MediaDrmCallback ​

java
private WidevineMediaDrmCallback createMediaDrmCallback(
  String licenseUrl, String[] keyRequestPropertiesArray) {
  HttpDataSource.Factory licenseDataSourceFactory =
      buildHttpDataSourceFactory();
  WidevineMediaDrmCallback drmCallback =
      new WidevineMediaDrmCallback(licenseUrl, licenseDataSourceFactory);
  if (keyRequestPropertiesArray != null) {
      for (int i = 0; i < keyRequestPropertiesArray.length - 1; i += 2) {
          drmCallback.setKeyRequestProperty(keyRequestPropertiesArray[i],
              keyRequestPropertiesArray[i + 1]);
      }
  }
  return drmCallback;
}

3.2. Create DrmSessionManager ​

java
private DrmSessionManager createDrmSessionManager() {
  DrmSessionManager drmSessionManager;
  if (Util.SDK_INT >= 18) {
    try {
      UUID drmSchemeUuid = Assertions.checkNotNull(Util.getDrmUuid("widevine"));
      MediaDrmCallback drmCallback = createMediaDrmCallback(LICENSE_URL, null);
      drmSessionManager =
        new DefaultDrmSessionManager.Builder()
            // FIXME: If you use license encrypt feature please uncomment line below
            // .setUuidAndExoMediaDrmProvider(drmSchemeUuid, SigmaMediaDrm.DEFAULT_PROVIDER)
            .setUuidAndExoMediaDrmProvider(drmSchemeUuid, FrameworkMediaDrm.DEFAULT_PROVIDER)
            .setMultiSession(true)
            .build(drmCallback);
    }
    catch (Exception ex) {
      drmSessionManager = null;
    }
  } else {
    drmSessionManager = null;
  }
  return drmSessionManager;
}

3.3. Create Media Item ​

java
private static List<MediaItem> createMediaItems(String mediaUrl) {
  List<MediaItem> mediaItems = new ArrayList<>();
  mediaItems.add(createMediaItem(mediaUrl));
  return mediaItems;
}

private static MediaItem createMediaItem(String mediaUrl) {
  MediaItem.Builder mediaItem = new MediaItem.Builder();
  mediaItem.setUri(Uri.parse(mediaUrl));
  mediaItem.setDrmUuid(Assertions.checkNotNull(Util.getDrmUuid("widevine")));
  mediaItem.setDrmLicenseUri(MediaInfo.getInstance().licenseUrl());
  mediaItem.setDrmMultiSession(true);
  return mediaItem.build();
}

3.4. Build Factory ​

java
public HttpDataSource.Factory buildHttpDataSourceFactory() {
  return new DefaultHttpDataSourceFactory(userAgent);
}
private DataSource.Factory buildDataSourceFactory() {
  DefaultDataSourceFactory upstreamFactory =
    new DefaultDataSourceFactory(this, buildHttpDataSourceFactory());
  return buildReadOnlyCacheDataSource(upstreamFactory, getDownloadCache());
}
private RenderersFactory buildRenderersFactory(boolean preferExtensionDecoders) {
  int extensionRendererMode =
    useExtensionRenderers()
      ? (preferExtensionRenderer
      ? DefaultRenderersFactory.EXTENSION_RENDERER_MODE_PREFER
      : DefaultRenderersFactory.EXTENSION_RENDERER_MODE_ON)
      : DefaultRenderersFactory.EXTENSION_RENDERER_MODE_OFF;
  return new DefaultRenderersFactory(/* context= */ this)
      .setExtensionRendererMode(extensionRendererMode);
}

3.5. Init Player with MediaSource ​

java
protected boolean initializePlayer() {
  DrmSessionManager drmSessionManager = createDrmSessionManager();

  DataSource.Factory dataSourceFactory = buildDataSourceFactory();
  trackSelector = new DefaultTrackSelector(this, new AdaptiveTrackSelection.Factory());
  DefaultTrackSelector.Parameters trackSelectionParameters =
    new DefaultTrackSelector.ParametersBuilder(this)
      .setAllowVideoMixedMimeTypeAdaptiveness(true)
      .setAllowVideoNonSeamlessAdaptiveness(true)
      .build();
  MediaSourceFactory mediaSourceFactory =
    new DefaultMediaSourceFactory(dataSourceFactory)
      .setDrmSessionManager(drmSessionManager)
      .setAdViewProvider(playerView);
  player =
    new SimpleExoPlayer.Builder(/* context= */ this, buildRenderersFactory.buildRenderersFactory(true))
      .setMediaSourceFactory(mediaSourceFactory)
      .setTrackSelector(trackSelector)
      .build();
  player.setPlayWhenReady(true);
  playerView.setPlayer(player);
  player.setMediaItems(createMediaItems(MEDIA_URL));
  player.prepare();
  return true;
}
