If called with suppressPlaybackOnUnsuitableOutput = true, then a playback attempt on an unsuitable audio output will result in calls to onPlaybackSuppressionReasonChanged with the value PLAYBACK_SUPPRESSION_REASON_UNSUITABLE_AUDIO_OUTPUT.

Callers of this may also want to enable setHandleAudioBecomingNoisy to prevent playback from continuing on the built-in speaker when a headset is disconnected.

Sets whether the player reports diagnostics data to the Android platform.

If enabled, the player will use the android.media.metrics.MediaMetricsManager to create a android.media.metrics.PlaybackSession and forward playback events and performance data to this session. This helps to provide system performance and debugging information for media playback on the device. This data may also be collected by Google if sharing usage and diagnostics data is enabled by the user of the device.

Parameters
boolean usePlatformDiagnostics	Whether the player reports diagnostics data to the Android platform.

Returns
ExoPlayer.Builder	This builder.

Throws
java.lang.IllegalStateException	If build has already been called.

setVideoChangeFrameRateStrategy

public ExoPlayer.Builder 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

Returns
ExoPlayer.Builder	This builder.

Throws
java.lang.IllegalStateException	If build has already been called.

setVideoScalingMode

@UnstableApi
public ExoPlayer.Builder setVideoScalingMode(@C.VideoScalingMode int videoScalingMode)

Sets the C.VideoScalingMode that will be used by the player.

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	A C.VideoScalingMode.

Returns
ExoPlayer.Builder	This builder.

Throws
java.lang.IllegalStateException	If build has already been called.

setWakeMode

@CanIgnoreReturnValue
public ExoPlayer.Builder setWakeMode(@C.WakeMode int wakeMode)

Sets the C.WakeMode that will be used by the player.

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 depend on the specified C.WakeMode.

Parameters
@C.WakeMode int wakeMode	A C.WakeMode.

Returns
ExoPlayer.Builder	This builder.

Throws
java.lang.IllegalStateException	If build has already been called.
