Constructor Detail

• Builder

  public Builder​(Context context)

  Creates a builder.

  Use Builder(Context, RenderersFactory), Builder(Context, MediaSourceFactory) or Builder(Context, RenderersFactory, MediaSourceFactory) instead, if you intend to provide a custom RenderersFactory, ExtractorsFactory or DefaultMediaSourceFactory. This is to ensure that ProGuard or R8 can remove ExoPlayer's DefaultRenderersFactory, DefaultExtractorsFactory and DefaultMediaSourceFactory from the APK.

  The builder uses the following default values:

  • RenderersFactory: DefaultRenderersFactory
  • TrackSelector: DefaultTrackSelector
  • MediaSourceFactory: DefaultMediaSourceFactory
  • LoadControl: DefaultLoadControl
  • BandwidthMeter: DefaultBandwidthMeter.getSingletonInstance(Context)
  • LivePlaybackSpeedControl: DefaultLivePlaybackSpeedControl
  • Looper: The Looper associated with the current thread, or the Looper of the application's main thread if the current thread doesn't have a Looper
  • AnalyticsCollector: AnalyticsCollector with Clock.DEFAULT
  • PriorityTaskManager: null (not used)
  • AudioAttributes: AudioAttributes.DEFAULT, not handling audio focus
  • C.WakeMode: C.WAKE_MODE_NONE
  • handleAudioBecomingNoisy: false
  • skipSilenceEnabled: false
  • C.VideoScalingMode: C.VIDEO_SCALING_MODE_DEFAULT
  • C.VideoChangeFrameRateStrategy: C.VIDEO_CHANGE_FRAME_RATE_STRATEGY_ONLY_IF_SEAMLESS
  • useLazyPreparation: true
  • SeekParameters: SeekParameters.DEFAULT
  • seekBackIncrementMs: C.DEFAULT_SEEK_BACK_INCREMENT_MS
  • seekForwardIncrementMs: C.DEFAULT_SEEK_FORWARD_INCREMENT_MS
  • releaseTimeoutMs: ExoPlayer.DEFAULT_RELEASE_TIMEOUT_MS
  • detachSurfaceTimeoutMs: ExoPlayer.DEFAULT_DETACH_SURFACE_TIMEOUT_MS
  • pauseAtEndOfMediaItems: false
  • Clock: Clock.DEFAULT

  Parameters:

  context - A Context.

  Sets a C.VideoChangeFrameRateStrategy that will be used by the player when provided with a video output Surface.

  The strategy only applies if a MediaCodec-based video Renderer is enabled. Applications wishing to use Surface.CHANGE_FRAME_RATE_ALWAYS should set the mode to C.VIDEO_CHANGE_FRAME_RATE_STRATEGY_OFF to disable calls to Surface.setFrameRate(float, int, int) from ExoPlayer, and should then call Surface.setFrameRate(float, int, int) directly from application code.
