## Public methods

### createChunkSource

```
abstract SsChunkSource createChunkSource(
    LoaderErrorThrower manifestLoaderErrorThrower,
    SsManifest manifest,
    int streamElementIndex,
    ExoTrackSelection trackSelection,
    @Nullable TransferListener transferListener,
    @Nullable CmcdConfiguration cmcdConfiguration
)
```

Creates a new `https://developer.android.com/reference/androidx/media3/exoplayer/smoothstreaming/SsChunkSource`.

| Parameters |
|---|---|
| `https://developer.android.com/reference/androidx/media3/exoplayer/upstream/LoaderErrorThrower manifestLoaderErrorThrower` | Throws errors affecting loading of manifests. |
| `https://developer.android.com/reference/androidx/media3/exoplayer/smoothstreaming/manifest/SsManifest manifest` | The initial manifest. |
| `int streamElementIndex` | The index of the corresponding stream element in the manifest. |
| `https://developer.android.com/reference/androidx/media3/exoplayer/trackselection/ExoTrackSelection trackSelection` | The track selection. |
| `@https://developer.android.com/reference/androidx/annotation/Nullable https://developer.android.com/reference/androidx/media3/datasource/TransferListener transferListener` | The transfer listener which should be informed of any data transfers. May be null if no listener is available. |
| `@https://developer.android.com/reference/androidx/annotation/Nullable https://developer.android.com/reference/androidx/media3/exoplayer/upstream/CmcdConfiguration cmcdConfiguration` | The `https://developer.android.com/reference/androidx/media3/exoplayer/upstream/CmcdConfiguration` for this chunk source. |

| Returns |
|---|---|
| `https://developer.android.com/reference/androidx/media3/exoplayer/smoothstreaming/SsChunkSource` | The created `https://developer.android.com/reference/androidx/media3/exoplayer/smoothstreaming/SsChunkSource`. |

### experimentalParseSubtitlesDuringExtraction

```
@CanIgnoreReturnValue
@ExperimentalApi
default SsChunkSource.Factory experimentalParseSubtitlesDuringExtraction(
    boolean parseSubtitlesDuringExtraction
)
```

Sets whether subtitles should be parsed as part of extraction (before being added to the sample queue) or as part of rendering (when being taken from the sample queue). Defaults to `false` (i.e. subtitles will be parsed as part of rendering).

This method is experimental and will be renamed or removed in a future release.

| Parameters |
|---|---|
| `boolean parseSubtitlesDuringExtraction` | Whether to parse subtitles during extraction or rendering. |

| Returns |
|---|---|
| `https://developer.android.com/reference/androidx/media3/exoplayer/smoothstreaming/SsChunkSource.Factory` | This factory, for convenience. |

### getOutputTextFormat

```
default Format getOutputTextFormat(Format sourceFormat)
```

Returns the output `https://developer.android.com/reference/androidx/media3/common/Format` of emitted `https://developer.android.com/reference/androidx/media3/common/C#TRACK_TYPE_TEXT()` which were originally in `sourceFormat`.

In many cases, where an `https://developer.android.com/reference/androidx/media3/extractor/Extractor` emits samples from the source without mutation, this method simply returns `sourceFormat`. In other cases, such as an `https://developer.android.com/reference/androidx/media3/extractor/Extractor` that transcodes subtitles from the `sourceFormat` to `https://developer.android.com/reference/androidx/media3/common/MimeTypes#APPLICATION_MEDIA3_CUES()`, the format is updated to indicate the transcoding that is taking place.

Non-text source formats are always returned without mutation.

| Parameters |
|---|---|
| `https://developer.android.com/reference/androidx/media3/common/Format sourceFormat` | The original text-based format. |

| Returns |
|---|---|
| `https://developer.android.com/reference/androidx/media3/common/Format` | The `https://developer.android.com/reference/androidx/media3/common/Format` that will be associated with a `https://developer.android.com/reference/androidx/media3/common/C#TRACK_TYPE_TEXT()`. |

### setSubtitleParserFactory

```
@CanIgnoreReturnValue
default SsChunkSource.Factory setSubtitleParserFactory(SubtitleParser.Factory subtitleParserFactory)
```

Sets the `https://developer.android.com/reference/androidx/media3/extractor/text/SubtitleParser.Factory` to use for parsing subtitles during extraction. The default factory value is implementation dependent.

| Parameters |
|---|---|
| `https://developer.android.com/reference/androidx/media3/extractor/text/SubtitleParser.Factory subtitleParserFactory` | The `https://developer.android.com/reference/androidx/media3/extractor/text/SubtitleParser.Factory` for parsing subtitles during extraction. |

| Returns |
|---|---|
| `https://developer.android.com/reference/androidx/media3/exoplayer/smoothstreaming/SsChunkSource.Factory` | This factory, for convenience. |
