Modifier and Type	Method	Description
`ChunkIndex`	`getChunkIndex()`	Returns the `ChunkIndex` most recently obtained from the chunks, or null if a `ChunkIndex` has not been obtained.
`Format[]`	`getSampleFormats()`	Returns the sample `Format`s for the tracks identified by the extractor, or null if the extractor has not finished identifying tracks.
`void`	`init(ChunkExtractor.TrackOutputProvider trackOutputProvider, long startTimeUs, long endTimeUs)`	Initializes the wrapper to output to `TrackOutput`s provided by the specified `ChunkExtractor.TrackOutputProvider`, and configures the extractor to receive data from a new chunk.
`boolean`	`read(ExtractorInput input)`	Reads from the given `ExtractorInput`.
`void`	`release()`	Releases any held resources.

  - getChunkIndex
```
@Nullable
ChunkIndex getChunkIndex()
```
    Returns the ChunkIndex most recently obtained from the chunks, or null if a ChunkIndex has not been obtained.
  - getSampleFormats
```
@Nullable
Format[] getSampleFormats()
```
    Returns the sample Formats for the tracks identified by the extractor, or null if the extractor has not finished identifying tracks.
  - init
```
void init(@Nullable
          ChunkExtractor.TrackOutputProvider trackOutputProvider,
          long startTimeUs,
          long endTimeUs)
```
    Initializes the wrapper to output to TrackOutputs provided by the specified ChunkExtractor.TrackOutputProvider, and configures the extractor to receive data from a new chunk.
    
    Parameters:
    
    trackOutputProvider - The provider of TrackOutputs that will receive sample data.
    
    startTimeUs - The start position in the new chunk, or C.TIME_UNSET to output samples from the start of the chunk.
    
    endTimeUs - The end position in the new chunk, or C.TIME_UNSET to output samples to the end of the chunk.
  - release
```
void release()
```
    Releases any held resources.
  - read
```
boolean read(ExtractorInput input)
      throws IOException
```
    Reads from the given ExtractorInput.
    
    Parameters:
    
    input - The input to read from.
    
    Returns:
    
    Whether there is any data left to extract. Returns false if the end of input has been reached.
    
    Throws:
