Whether this seeks repeats the current item.

setAudioAttributes

public void setAudioAttributes(
    AudioAttributes audioAttributes,
    boolean handleAudioFocus
)

Sets the attributes for audio playback, used by the underlying audio track. If not set, the default audio attributes will be used. They are suitable for general media playback.

Setting the audio attributes during playback may introduce a short gap in audio output as the audio track is recreated. A new audio session id will also be generated.

If tunneling is enabled by the track selector, the specified audio attributes will be ignored, but they will take effect if audio is later played without tunneling.

If the device is running a build before platform API version 21, audio attributes cannot be set directly on the underlying audio track. In this case, the usage will be mapped onto an equivalent stream type using getStreamTypeForAudioUsage.

If audio focus should be handled, the usage must be USAGE_MEDIA or USAGE_GAME. Other usages will throw an .

This method must only be called if COMMAND_SET_AUDIO_ATTRIBUTES is available.

setDeviceMuted

public void setDeviceMuted(boolean muted)

setDeviceMuted

public void setDeviceMuted(boolean muted, @C.VolumeFlags int flags)

Sets the mute state of the device.

Note that this method affects the device volume. To mute just the current stream, use setVolume(0) instead.

This method must only be called if COMMAND_ADJUST_DEVICE_VOLUME_WITH_FLAGS is available.

Parameters
boolean muted

Whether to set the device to be muted or not

@C.VolumeFlags int flags

Either 0 or a bitwise combination of one or more C.VolumeFlags.

setDeviceVolume

public void setDeviceVolume(int volume)

setDeviceVolume

public void setDeviceVolume(int volume, @C.VolumeFlags int flags)

Sets the volume of the device with volume flags.

Note that this method affects the device volume. To change the volume of the current stream only, use setVolume.

This method must only be called if COMMAND_SET_DEVICE_VOLUME_WITH_FLAGS is available.

Parameters
int volume

The volume to set.

@C.VolumeFlags int flags

Either 0 or a bitwise combination of one or more C.VolumeFlags.

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)

Unsupported parameters will be silently ignored.

Use getTrackSelectionParameters to retrieve the current parameters. For example, the following snippet restricts video to SD whilst keep other track selection parameters unchanged:

player.setTrackSelectionParameters(
  player.getTrackSelectionParameters()
        .buildUpon()
        .setMaxVideoSizeSd()
        .build())

This method must only be called if COMMAND_SET_TRACK_SELECTION_PARAMETERS is available.

setVideoChangeFrameRateStrategy

public void setVideoChangeFrameRateStrategy(
    @C.VideoChangeFrameRateStrategy 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
@C.VideoChangeFrameRateStrategy 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.

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(@C.VideoScalingMode 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
@C.VideoScalingMode int videoScalingMode

The C.VideoScalingMode.

setVideoSurface

public void setVideoSurface(@Nullable Surface surface)

Sets the Surface onto which video will be rendered. The caller is responsible for tracking the lifecycle of the surface, and must clear the surface by calling setVideoSurface(null) if the surface is destroyed.

If the surface is held by a SurfaceView, TextureView or then it's recommended to use setVideoSurfaceView, setVideoTextureView or setVideoSurfaceHolder rather than this method, since passing the holder allows the player to track the lifecycle of the surface automatically.

This method must only be called if COMMAND_SET_VIDEO_SURFACE is available.

Parameters
@Nullable Surface surface

The Surface.

setVideoSurfaceHolder

public void setVideoSurfaceHolder(@Nullable SurfaceHolder surfaceHolder)

Sets the SurfaceHolder that holds the Surface onto which video will be rendered. The player will track the lifecycle of the surface automatically.

The thread that calls the SurfaceHolder.Callback methods must be the thread associated with getApplicationLooper.

This method must only be called if COMMAND_SET_VIDEO_SURFACE is available.

Parameters
@Nullable SurfaceHolder surfaceHolder

The surface holder.

setVideoSurfaceView

public void setVideoSurfaceView(@Nullable SurfaceView surfaceView)

Sets the SurfaceView onto which video will be rendered. The player will track the lifecycle of the surface automatically.

The thread that calls the SurfaceHolder.Callback methods must be the thread associated with getApplicationLooper.

This method must only be called if COMMAND_SET_VIDEO_SURFACE is available.

Parameters
@Nullable SurfaceView surfaceView

The surface view.

setVideoTextureView

public void setVideoTextureView(@Nullable TextureView textureView)

Sets the TextureView onto which video will be rendered. The player will track the lifecycle of the surface automatically.

Consider using SurfaceView via setVideoSurfaceView instead of . SurfaceView generally causes lower battery consumption, and has better handling for HDR and secure content. See Choosing a surface type for more information.

The thread that calls the TextureView.SurfaceTextureListener methods must be the thread associated with getApplicationLooper.

This method must only be called if COMMAND_SET_VIDEO_SURFACE is available.

Parameters
@Nullable TextureView textureView

The texture view.

setVolume

public void setVolume(float volume)

Sets the audio volume, valid values are between 0 (silence) and 1 (unity gain, signal unchanged), inclusive.

This method must only be called if COMMAND_SET_VOLUME is available.

Parameters
float volume

Linear output gain to apply to all audio channels.

setWakeMode

public void setWakeMode(@C.WakeMode 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
@C.WakeMode int wakeMode

The C.WakeMode option to keep the device awake during playback.

stop

public void stop()

Stops playback without resetting the playlist. Use pause rather than this method if the intention is to pause playback.

Calling this method will cause the playback state to transition to STATE_IDLE and the player will release the loaded media and resources required for playback. The player instance can still be used by calling prepare again, and release must still be called on the player if it's no longer required.

Calling this method does not clear the playlist, reset the playback position or the playback error.

This method must only be called if COMMAND_STOP is available.
