*** ** * ** ***
A `https://developer.android.com/reference/kotlin/androidx/media3/common/Player` implementation that plays `https://developer.android.com/reference/kotlin/androidx/media3/transformer/Composition` of media assets. The `https://developer.android.com/reference/kotlin/androidx/media3/transformer/Composition` specifies how the assets should be arranged, and the audio and video effects to apply to them.
`CompositionPlayer` instances must be accessed from a single application thread. For the vast majority of cases this should be the application's main thread. The thread on which a CompositionPlayer instance must be accessed can be explicitly specified by passing a `https://developer.android.com/reference/android/os/Looper.html` when creating the player. If no `https://developer.android.com/reference/android/os/Looper.html` is specified, then the `https://developer.android.com/reference/android/os/Looper.html` of the thread that the player is created on is used, or if that thread does not have a `https://developer.android.com/reference/android/os/Looper.html`, the `https://developer.android.com/reference/android/os/Looper.html` of the application's main thread is used. In all cases the `https://developer.android.com/reference/android/os/Looper.html` of the thread from which the player must be accessed can be queried using `https://developer.android.com/reference/kotlin/androidx/media3/common/SimpleBasePlayer#getApplicationLooper()`.
This player only supports setting the `https://developer.android.com/reference/kotlin/androidx/media3/common/SimpleBasePlayer#setRepeatMode(int)` as `https://developer.android.com/reference/kotlin/androidx/media3/common/Player#REPEAT_MODE_ALL()` of the `https://developer.android.com/reference/kotlin/androidx/media3/transformer/Composition`, or `https://developer.android.com/reference/kotlin/androidx/media3/common/Player#REPEAT_MODE_OFF()`.

### addAnalyticsListener
```
fun addAnalyticsListener(listener: AnalyticsListener!): Unit
```
Adds an `https://developer.android.com/reference/kotlin/androidx/media3/exoplayer/analytics/AnalyticsListener` to receive analytics events.
This method can be called from any thread.
| Parameters |
|---|---|
| `listener: https://developer.android.com/reference/kotlin/androidx/media3/exoplayer/analytics/AnalyticsListener!` | The listener to be added. |
### experimentalRedrawLastFrame
```
@ExperimentalApi
fun experimentalRedrawLastFrame(): Unit
```
Forces the effect pipeline to redraw the effects immediately.
The player must be `https://developer.android.com/reference/kotlin/androidx/media3/transformer/CompositionPlayer.Builder#experimentalSetEnableReplayableCache(boolean)`, unless using `https://developer.android.com/reference/kotlin/androidx/media3/transformer/CompositionPlayer.Builder#setFrameProcessorFactory(androidx.media3.common.video.FrameProcessor.Factory)` to apply effects.
### getPlaybackLooper
```
fun getPlaybackLooper(): Looper!
```
Returns the `https://developer.android.com/reference/android/os/Looper.html` associated with the playback thread.
This method may be called from any thread.
### isScrubbingModeEnabled
```
fun isScrubbingModeEnabled(): Boolean
```
Returns whether the player is optimized for scrubbing (many frequent seeks).
See `https://developer.android.com/reference/kotlin/androidx/media3/transformer/CompositionPlayer#setScrubbingModeEnabled(boolean)`.
### removeAnalyticsListener
```
fun removeAnalyticsListener(listener: AnalyticsListener!): Unit
```
Removes an `https://developer.android.com/reference/kotlin/androidx/media3/exoplayer/analytics/AnalyticsListener`.
| Parameters |
|---|---|
| `listener: https://developer.android.com/reference/kotlin/androidx/media3/exoplayer/analytics/AnalyticsListener!` | The listener to be removed. |
### setComposition
```
fun setComposition(composition: Composition!): Unit
```
Sets the `https://developer.android.com/reference/kotlin/androidx/media3/transformer/Composition` to play from the beginning.
Calling this method is equivalent to calling `https://developer.android.com/reference/kotlin/androidx/media3/transformer/CompositionPlayer#setComposition(androidx.media3.transformer.Composition,long)` with a start position at zero.
| Parameters |
|---|---|
| `composition: https://developer.android.com/reference/kotlin/androidx/media3/transformer/Composition!` | The `https://developer.android.com/reference/kotlin/androidx/media3/transformer/Composition` to play. Every `https://developer.android.com/reference/kotlin/androidx/media3/transformer/EditedMediaItem` in the `https://developer.android.com/reference/kotlin/androidx/media3/transformer/Composition` must have its `https://developer.android.com/reference/kotlin/androidx/media3/transformer/EditedMediaItem#durationUs()` set. |
### setComposition
```
fun setComposition(
composition: Composition!,
startPositionMs: @IntRange(from = 0) Long
): Unit
```
Sets the `https://developer.android.com/reference/kotlin/androidx/media3/transformer/Composition` to play.
| Parameters |
|---|---|
| `composition: https://developer.android.com/reference/kotlin/androidx/media3/transformer/Composition!` | The `https://developer.android.com/reference/kotlin/androidx/media3/transformer/Composition` to play.

### setScrubbingModeEnabled
```
fun setScrubbingModeEnabled(scrubbingModeEnabled: Boolean): Unit
```
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).

### setVideoSurface
```
fun setVideoSurface(surface: Surface!, videoOutputSize: Size!): Unit

## Protected functions
### getState
```
protected fun getState(): SimpleBasePlayer.State!
```
Returns the current `https://developer.android.com/reference/kotlin/androidx/media3/common/SimpleBasePlayer.State` of the player.
The `https://developer.android.com/reference/kotlin/androidx/media3/common/SimpleBasePlayer.State` should include all `https://developer.android.com/reference/kotlin/androidx/media3/common/SimpleBasePlayer.State.Builder#setAvailableCommands(androidx.media3.common.Player.Commands)` indicating which player methods are allowed to be called.
Note that this method won't be called while asynchronous handling of player methods is in progress. This means that the implementation doesn't need to handle state changes caused by these asynchronous operations until they are done and can return the currently known state directly. The placeholder state used while these asynchronous operations are in progress can be customized by overriding `https://developer.android.com/reference/kotlin/androidx/media3/common/SimpleBasePlayer#getPlaceholderState(androidx.media3.common.SimpleBasePlayer.State)` if required.
