Whether the renderer is ready for the `https://developer.android.com/reference/kotlin/androidx/media3/exoplayer/ExoPlayer` instance to transition to `https://developer.android.com/reference/kotlin/androidx/media3/common/Player#STATE_ENDED()`. The player will make this transition as soon as `true` is returned by all of its renderers.

### maybeThrowStreamError

```
fun maybeThrowStreamError(): Unit
```

Throws an error that's preventing the renderer from reading from its `https://developer.android.com/reference/kotlin/androidx/media3/exoplayer/source/SampleStream`. Does nothing if no such error exists.

This method may be called when the renderer is in the following states: `https://developer.android.com/reference/kotlin/androidx/media3/exoplayer/Renderer#STATE_ENABLED()`, `https://developer.android.com/reference/kotlin/androidx/media3/exoplayer/Renderer#STATE_STARTED()`.

### render

```
fun render(positionUs: Long, elapsedRealtimeUs: Long): Unit
```

Incrementally renders the `https://developer.android.com/reference/kotlin/androidx/media3/exoplayer/source/SampleStream`.

If the renderer is in the `https://developer.android.com/reference/kotlin/androidx/media3/exoplayer/Renderer#STATE_ENABLED()` state then each call to this method will do work toward being ready to render the `https://developer.android.com/reference/kotlin/androidx/media3/exoplayer/source/SampleStream` when the renderer is started. If the renderer is in the `https://developer.android.com/reference/kotlin/androidx/media3/exoplayer/Renderer#STATE_STARTED()` state then calls to this method will render the `https://developer.android.com/reference/kotlin/androidx/media3/exoplayer/source/SampleStream` in sync with the specified media positions.

The renderer may also render the very start of the media at the current position (e.g. the first frame of a video stream) while still in the `https://developer.android.com/reference/kotlin/androidx/media3/exoplayer/Renderer#STATE_ENABLED()` state, unless it's the initial start of the media after calling `https://developer.android.com/reference/kotlin/androidx/media3/exoplayer/Renderer#enable(androidx.media3.exoplayer.RendererConfiguration,androidx.media3.common.Format[],androidx.media3.exoplayer.source.SampleStream,long,boolean,boolean,long,long,androidx.media3.exoplayer.source.MediaSource.MediaPeriodId)` with `
mayRenderStartOfStream` set to `false`.

This method should return quickly, and should not block if the renderer is unable to make useful progress.

This method may be called when the renderer is in the following states: `https://developer.android.com/reference/kotlin/androidx/media3/exoplayer/Renderer#STATE_ENABLED()`, `https://developer.android.com/reference/kotlin/androidx/media3/exoplayer/Renderer#STATE_STARTED()`.

| Parameters |
|---|---|
| `positionUs: https://kotlinlang.org/api/core/kotlin-stdlib/kotlin/-long/index.html` | The current media time in microseconds, measured at the start of the current iteration of the rendering loop. |
| `elapsedRealtimeUs: https://kotlinlang.org/api/core/kotlin-stdlib/kotlin/-long/index.html` | `https://developer.android.com/reference/android/os/SystemClock.html#elapsedRealtime()` in microseconds, measured at the start of the current iteration of the rendering loop. |

| Throws |
|---|---|
| `https://developer.android.com/reference/kotlin/androidx/media3/exoplayer/ExoPlaybackException` | If an error occurs. |

| `startPositionUs: https://kotlinlang.org/api/core/kotlin-stdlib/kotlin/-long/index.html` | The start position of the new stream in renderer time (microseconds). |
| `offsetUs: https://kotlinlang.org/api/core/kotlin-stdlib/kotlin/-long/index.html` | The offset to be added to timestamps of buffers read from `stream` before they are rendered. |
| `mediaPeriodId: https://developer.android.com/reference/kotlin/androidx/media3/exoplayer/source/MediaSource.MediaPeriodId!` | The `https://developer.android.com/reference/kotlin/androidx/media3/exoplayer/source/MediaSource.MediaPeriodId` of the `https://developer.android.com/reference/kotlin/androidx/media3/exoplayer/source/MediaPeriod` producing the ` stream`. |

### reset

```
fun reset(): Unit
```

Forces the renderer to give up any resources (e.g. media decoders) that it may be holding. If the renderer is not holding any resources, the call is a no-op.

This method may be called when the renderer is in the following states: `https://developer.android.com/reference/kotlin/androidx/media3/exoplayer/Renderer#STATE_DISABLED()`.

### resetPosition

```
fun resetPosition(positionUs: Long, sampleStreamIsResetToKeyFrame: Boolean): Unit

If `sampleStreamIsResetToKeyFrame` is `true` then after the position discontinuity, the renderer's `https://developer.android.com/reference/kotlin/androidx/media3/exoplayer/source/SampleStream` is guaranteed to provide samples starting from a key frame.

`sampleStreamIsResetToKeyFrame` is guaranteed to be `true` unless the implementation overrides `https://developer.android.com/reference/kotlin/androidx/media3/exoplayer/Renderer#supportsResetPositionWithoutKeyFrameReset(long)` to return `true`.

This method may be called when the renderer is in the following states: `https://developer.android.com/reference/kotlin/androidx/media3/exoplayer/Renderer#STATE_ENABLED()`, `https://developer.android.com/reference/kotlin/androidx/media3/exoplayer/Renderer#STATE_STARTED()`.

| `sampleStreamIsResetToKeyFrame: https://kotlinlang.org/api/core/kotlin-stdlib/kotlin/-boolean/index.html` | Whether the renderer's `https://developer.android.com/reference/kotlin/androidx/media3/exoplayer/source/SampleStream` is guaranteed to provide samples starting from a key frame. |

| Throws |
|---|---|
| `https://developer.android.com/reference/kotlin/androidx/media3/exoplayer/ExoPlaybackException` | If an error occurs handling the reset. |

### setCurrentStreamFinal
