A `https://developer.android.com/reference/androidx/media3/extractor/SeekMap` implementation for FLAC streams that contain a [seek table](https://www.rfc-editor.org/rfc/rfc9639.html#name-seek-table).

## Summary

| ### Public constructors |
|---|
| `https://developer.android.com/reference/androidx/media3/extractor/FlacSeekTableSeekMap#FlacSeekTableSeekMap(androidx.media3.extractor.FlacStreamMetadata,long)( https://developer.android.com/reference/androidx/media3/extractor/FlacStreamMetadata flacStreamMetadata, long firstFrameOffset )` Creates a seek map from the FLAC stream seek table. |

| ### Public methods |
|---|---|
| `long` | `https://developer.android.com/reference/androidx/media3/extractor/FlacSeekTableSeekMap#getDurationUs()()` Returns the duration of the stream in microseconds. |
| `https://developer.android.com/reference/androidx/media3/extractor/SeekMap.SeekPoints` | `https://developer.android.com/reference/androidx/media3/extractor/FlacSeekTableSeekMap#getSeekPoints(long)(long timeUs)` Obtains seek points for the specified seek time in microseconds. |
| `boolean` | `https://developer.android.com/reference/androidx/media3/extractor/FlacSeekTableSeekMap#isSeekable()()` Returns whether seeking is supported. |

| ### Inherited methods |
|---|
| From [androidx.media3.extractor.SeekMap](https://developer.android.com/reference/androidx/media3/extractor/SeekMap) |---|---| | `boolean` | `https://developer.android.com/reference/androidx/media3/extractor/SeekMap#isEstimated()()` Returns whether this `https://developer.android.com/reference/androidx/media3/extractor/SeekMap` is based on estimations. | |

## Public constructors

### FlacSeekTableSeekMap

```
public FlacSeekTableSeekMap(
    FlacStreamMetadata flacStreamMetadata,
    long firstFrameOffset
)
```

Creates a seek map from the FLAC stream seek table.

| Parameters |
|---|---|
| `https://developer.android.com/reference/androidx/media3/extractor/FlacStreamMetadata flacStreamMetadata` | The stream metadata. |
| `long firstFrameOffset` | The byte offset of the first frame in the stream. |

## Public methods

### getDurationUs

```
public long getDurationUs()
```

Returns the duration of the stream in microseconds.

| Returns |
|---|---|
| `long` | The duration of the stream in microseconds, or `https://developer.android.com/reference/androidx/media3/common/C#TIME_UNSET()` if the duration is unknown. |

### getSeekPoints

```
public SeekMap.SeekPoints getSeekPoints(long timeUs)
```

Obtains seek points for the specified seek time in microseconds. The returned `https://developer.android.com/reference/androidx/media3/extractor/SeekMap.SeekPoints` will contain one or two distinct seek points.

Two seek points \[A, B\] are returned in the case that seeking can only be performed to discrete points in time, there does not exist a seek point at exactly the requested time, and there exist seek points on both sides of it. In this case A and B are the closest seek points before and after the requested time. A single seek point is returned in all other cases.

| Parameters |
|---|---|
| `long timeUs` | A seek time in microseconds. |

| Returns |
|---|---|
| `https://developer.android.com/reference/androidx/media3/extractor/SeekMap.SeekPoints` | The corresponding seek points. |

### isSeekable

```
public boolean isSeekable()
```

Returns whether seeking is supported.

| Returns |
|---|---|
| `boolean` | Whether seeking is supported. |
