StubExoPlayer

An abstract ExoPlayer implementation that throws UnsupportedOperationException from every method.

An extensible media player that plays MediaSources. Instances can be obtained from .

Player components

ExoPlayer is designed to make few assumptions about (and hence impose few restrictions on) the type of the media being played, how and where it is stored, and how it is rendered. Rather than implementing the loading and rendering of media directly, ExoPlayer implementations delegate this work to components that are injected when a player is created or when it's prepared for playback. Components common to all ExoPlayer implementations are:

MediaSources that define the media to be played, load the media, and from which the loaded media can be read. MediaSources are created from MediaItems by the MediaSource.Factory injected into the player Builder, or can be added directly by methods like setMediaSource. The library provides a DefaultMediaSourceFactory for progressive media files, DASH, SmoothStreaming and HLS, which also includes functionality for side-loading subtitle files and clipping media.
Renderers that render individual components of the media. The library provides default implementations for common media types (MediaCodecVideoRenderer, MediaCodecAudioRenderer, TextRenderer and MetadataRenderer). A Renderer consumes media from the MediaSource being played. Renderers are injected when the player is created. The number of renderers and their respective track types can be obtained by calling getRendererCount and getRendererType.
A TrackSelector that selects tracks provided by the MediaSource to be consumed by each of the available Renderers. The library provides a default implementation (DefaultTrackSelector) suitable for most use cases. A TrackSelector is injected when the player is created.
A LoadControl that controls when the MediaSource buffers more media, and how much media is buffered. The library provides a default implementation () suitable for most use cases. A LoadControl is injected when the player is created.

An ExoPlayer can be built using the default components provided by the library, but may also be built using custom implementations if non-standard behaviors are required. For example a custom LoadControl could be injected to change the player's buffering strategy, or a custom Renderer could be injected to add support for a video codec not supported natively by Android.

The concept of injecting components that implement pieces of player functionality is present throughout the library. The default component implementations listed above delegate work to further injected components. This allows many sub-components to be individually replaced with custom implementations. For example the default MediaSource implementations require one or more DataSource factories to be injected via their constructors. By providing a custom factory it's possible to load data from a non-standard source, or through a different network stack.

Threading model

The figure below shows ExoPlayer's threading model.

ExoPlayer's threading model

ExoPlayer instances must be accessed from a single application thread unless indicated otherwise. For the vast majority of cases this should be the application's main thread. Using the application's main thread is also a requirement when using ExoPlayer's UI components or the IMA extension. The thread on which an ExoPlayer instance must be accessed can be explicitly specified by passing a `Looper` when creating the player. If no `Looper` is specified, then the `Looper` of the thread that the player is created on is used, or if that thread does not have a `Looper`, the `Looper` of the application's main thread is used. In all cases the `Looper` of the thread from which the player must be accessed can be queried using getApplicationLooper.
Registered listeners are called on the thread associated with getApplicationLooper. Note that this means registered listeners are called on the same thread which must be used to access the player.
An internal playback thread is responsible for playback. Injected player components such as Renderers, MediaSources, TrackSelectors and LoadControls are called by the player on this thread.
When the application performs an operation on the player, for example a seek, a message is delivered to the internal playback thread via a message queue. The internal playback thread consumes messages from the queue and performs the corresponding operations. Similarly, when a playback event occurs on the internal playback thread, a message is delivered to the application thread via a second message queue. The application thread consumes messages from the queue, updating the application visible state and calling corresponding listener methods.
Injected player components may use additional background threads. For example a MediaSource may use background threads to load data. These are implementation specific.

replaceMediaItems

abstract void replaceMediaItems(
    int fromIndex,
    int toIndex,
    List<MediaItem> mediaItems
)

Replaces the media items at the given range of the playlist.

Implementations of this method may attempt to seamlessly continue playback if the currently playing media item is replaced with a compatible one (e.g. same URL, only metadata has changed).

This method must only be called if #COMMAND_CHANGE_MEDIA_ITEMS is * #getAvailableCommands() available.

Note that it is possible to replace a range with an arbitrary number of new items, so that the number of removed items defined by fromIndex} and toIndex} does not have to match the number of added items defined by mediaItems}. As result, it may also change the index of subsequent items not touched by this operation.

ExoPlayer will keep the existing MediaSource instances for the new MediaItems if supported by all of these instances. If the current item is replaced, this will also not interrupt the ongoing playback.

setAudioSessionId

@UnstableApi
abstract void setAudioSessionId(int audioSessionId)

Sets the ID of the audio session to attach to the underlying android.media.AudioTrack.

The audio session ID can be generated using generateAudioSessionIdV21 for API 21+.

setCameraMotionListener

@UnstableApi
abstract void setCameraMotionListener(CameraMotionListener listener)

Sets a listener of camera motion events.

Parameters
`CameraMotionListener listener`	The listener.

setForegroundMode

@UnstableApi
abstract 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

abstract void setHandleAudioBecomingNoisy(boolean handleAudioBecomingNoisy)

@UnstableApi
abstract 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

@RequiresApi(value = 18)
@UnstableApi
abstract void setVideoEffects(List<Effect> videoEffects)

If passing a surface to the player directly, the output resolution needs to be signaled by passing a renderer message 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 updating the timestamps.
This feature does not work with DRM-protected content.
This method should be called before calling prepare.

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

setVideoFrameMetadataListener

@UnstableApi
abstract 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

@UnstableApi
abstract 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`.

setWakeMode

abstract 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.
