setAuxEffectInfo

public void setAuxEffectInfo(AuxEffectInfo auxEffectInfo)

Sets information on an auxiliary audio effect to attach to the underlying audio track.

setCameraMotionListener

public void setCameraMotionListener(CameraMotionListener listener)

Sets a listener of camera motion events.

Parameters
`CameraMotionListener listener`	The listener.

setForegroundMode

public void setForegroundMode(boolean foregroundMode)

Sets whether the player is allowed to keep holding limited resources such as video decoders, even when in the idle state. By doing so, the player may be able to reduce latency when starting to play another piece of content for which the same resources are required.

This mode should be used with caution, since holding limited resources may prevent other players of media components from acquiring them. It should only be enabled when both of the following conditions are true:

The application that owns the player is in the foreground.
The player is used in a way that may benefit from foreground mode. For this to be true, the same player instance must be used to play multiple pieces of content, and there must be gaps between the playbacks (i.e. stop is called to halt one playback, and prepare is called some time later to start a new one).

Note that foreground mode is not useful for switching between content without gaps between the playbacks. For this use case stop does not need to be called, and simply calling prepare for the new media will cause limited resources to be retained even if foreground mode is not enabled.

If foreground mode is enabled, it's the application's responsibility to disable it when the conditions described above no longer hold.

Parameters
`boolean foregroundMode`	Whether the player is allowed to keep limited resources even when in the idle state.

setHandleAudioBecomingNoisy

public void setHandleAudioBecomingNoisy(boolean handleAudioBecomingNoisy)

    List<MediaSource> mediaSources,
    int startMediaItemIndex,
    long startPositionMs
)

Clears the playlist and adds the specified MediaSources.

Parameters
`List<MediaSource> mediaSources`	The new `MediaSources`.
`int startMediaItemIndex`	The media item index to start playback from. If `INDEX_UNSET` is passed, the current position is not reset.
`long startPositionMs`	The position in milliseconds to start playback from. If `TIME_UNSET` is passed, the default position of the given media source is used. In any case, if `startMediaItemIndex` is set to `INDEX_UNSET`, this parameter is ignored and the position is not reset at all.

setPauseAtEndOfMediaItems

public void setPauseAtEndOfMediaItems(boolean pauseAtEndOfMediaItems)

Sets whether to pause playback at the end of each media item.

This means the player will pause at the end of each window in the current timeline. Listeners will be informed by a call to onPlayWhenReadyChanged with the reason PLAY_WHEN_READY_CHANGE_REASON_END_OF_MEDIA_ITEM when this happens.

Parameters
`boolean pauseAtEndOfMediaItems`	Whether to pause playback at the end of each media item.

setPreferredAudioDevice

public void setPreferredAudioDevice(@Nullable AudioDeviceInfo audioDeviceInfo)

Sets the preferred audio device.

Parameters
`@Nullable AudioDeviceInfo audioDeviceInfo`	The preferred `audio device`, or null to restore the default.

public void setPreloadConfiguration(
    ExoPlayer.PreloadConfiguration preloadConfiguration
)

Sets the preload configuration to configure playlist preloading.

Parameters
`ExoPlayer.PreloadConfiguration preloadConfiguration`	The preload configuration.

setPriority

public void setPriority(@C.Priority int priority)

Sets the C.Priority for this player.

The priority may influence resource allocation between multiple players or other components running in the same app.

This priority is used for the PriorityTaskManager, if set.

Parameters
`@C.Priority int priority`	The `C.Priority`.

setPriorityTaskManager

public void setPriorityTaskManager(
    @Nullable PriorityTaskManager priorityTaskManager
)

Sets a PriorityTaskManager, or null to clear a previously set priority task manager.

The priority set via setPriority (or by default) will be set while the player is loading.

Parameters
`@Nullable PriorityTaskManager priorityTaskManager`	The `PriorityTaskManager`, or null to clear a previously set priority task manager.

setScrubbingModeEnabled

public void setScrubbingModeEnabled(boolean scrubbingModeEnabled)

Sets whether to optimize the player for scrubbing (many frequent seeks).

The player may consume more resources in this mode, so it should only be used for short periods of time in response to user interaction (e.g. dragging on a progress bar UI element).

During scrubbing mode playback is suppressed with PLAYBACK_SUPPRESSION_REASON_SCRUBBING.

Parameters
`boolean scrubbingModeEnabled`	Whether scrubbing mode should be enabled.

setScrubbingModeParameters

public void setScrubbingModeParameters(
    ScrubbingModeParameters scrubbingModeParameters
)

Sets the parameters that control behavior in scrubbing mode.

setSeekParameters

public void setSeekParameters(@Nullable SeekParameters seekParameters)

Sets the parameters that control how seek operations are performed.

Parameters
`@Nullable SeekParameters seekParameters`	The seek parameters, or `null` to use the defaults.

setShuffleOrder

public void setShuffleOrder(ShuffleOrder shuffleOrder)

Sets the shuffle order.

The ShuffleOrder passed must have the same length as the current playlist (getMediaItemCount).

Parameters
`ShuffleOrder shuffleOrder`	The shuffle order.

setSkipSilenceEnabled

public void setSkipSilenceEnabled(boolean skipSilenceEnabled)

Sets whether skipping silences in the audio stream is enabled.

Parameters
`boolean skipSilenceEnabled`	Whether skipping silences in the audio stream is enabled.

setVideoChangeFrameRateStrategy

public void setVideoChangeFrameRateStrategy(int videoChangeFrameRateStrategy)

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 CHANGE_FRAME_RATE_ALWAYS should set the mode to VIDEO_CHANGE_FRAME_RATE_STRATEGY_OFF to disable calls to setFrameRate from ExoPlayer, and should then call setFrameRate directly from application code.

Parameters
`int videoChangeFrameRateStrategy`	A `C.VideoChangeFrameRateStrategy`.

setVideoEffects

public void setVideoEffects(List<Effect> videoEffects)

Sets a List of video effects that will be applied to each video frame.

If passing a surface to the player directly, the output resolution needs to be signaled by passing a message to the video renderer with type MSG_SET_VIDEO_OUTPUT_RESOLUTION after calling this method. For SurfaceView, TextureView and SurfaceHolder output this happens automatically.

Pass REDRAW to force the effect pipeline to redraw the effects immediately. To accurately interleave redraws, listen to onVideoFrameAboutToBeRendered events.

The following limitations exist for using video effects:

The androidx.media3:media3-effect module must be available on the runtime classpath. androidx.media3:media3-exoplayer does not explicitly depend on the effect module, so apps must make sure it's available themselves. It must be the same version as the rest of the androidx.media3 modules being used by the app.
This feature works only with the default MediaCodecVideoRenderer and not custom or extension video renderers.
This feature does not work with effects that update the frame timestamps.
This feature does not work with DRM-protected content.
This method must be called at least once before calling prepare (in order to set up the effects pipeline). The effects can be changed during playback by subsequent calls to this method after prepare.

Parameters
`List<Effect> videoEffects`	The `List` of `video effects` to apply.

setVideoFrameMetadataListener

public void setVideoFrameMetadataListener(VideoFrameMetadataListener listener)

Sets a listener to receive video frame metadata events.

This method is intended to be called by the same component that sets the Surface onto which video will be rendered. If using ExoPlayer's standard UI components, this method should not be called directly from application code.

Parameters
`VideoFrameMetadataListener listener`	The listener.

setVideoScalingMode

public void setVideoScalingMode(int videoScalingMode)

Sets the C.VideoScalingMode.

The scaling mode only applies if a MediaCodec-based video Renderer is enabled and if the output surface is owned by a SurfaceView.

Parameters
`int videoScalingMode`	The `C.VideoScalingMode`.

setWakeMode

public void setWakeMode(int wakeMode)

Sets how the player should keep the device awake for playback when the screen is off.

Enabling this feature requires the WAKE_LOCK permission. It should be used together with a foreground android.app.Service for use cases where playback occurs and the screen is off (e.g. background audio playback). It is not useful when the screen will be kept on during playback (e.g. foreground video playback).

When enabled, the locks (android.os.PowerManager.WakeLock / ) will be held whenever the player is in the STATE_READY or STATE_BUFFERING states with playWhenReady = true. The locks held depends on the specified C.WakeMode.

Parameters
`int wakeMode`	The `C.WakeMode` option to keep the device awake during playback.
