ChunkExtractor

Kotlin |Java

@UnstableApi
interface ChunkExtractor

Known direct subclasses

`BundledChunkExtractor`	`ChunkExtractor` implementation that uses ExoPlayer app-bundled `Extractors`.
`MediaParserChunkExtractor`	`ChunkExtractor` implemented on top of the platform's `MediaParser`.

Extracts samples and track Formats from chunks.

The TrackOutputProvider passed to init provides the TrackOutputs that receive the extracted data.

Summary

Nested types
`interface ChunkExtractor.Factory` Creates `ChunkExtractor` instances.
`interface ChunkExtractor.TrackOutputProvider` Provides `TrackOutput` instances to be written to during extraction.

Public functions
`ChunkIndex?`	`getChunkIndex()` Returns the `ChunkIndex` most recently obtained from the chunks, or null if a has not been obtained.
`Array<Format!>?`	`getSampleFormats()` Returns the sample `Format`s for the tracks identified by the extractor, or null if the extractor has not finished identifying tracks.
`Unit`	`init( trackOutputProvider: ChunkExtractor.TrackOutputProvider?, startTimeUs: Long, endTimeUs: Long )` Initializes the wrapper to output to `TrackOutput`s provided by the specified , and configures the extractor to receive data from a new chunk.
`Boolean`	`read(input: ExtractorInput!)` Reads from the given `ExtractorInput`.
`Unit`	`release()` Releases any held resources.

fun getChunkIndex(): ChunkIndex?

Returns the ChunkIndex most recently obtained from the chunks, or null if a has not been obtained.

fun getSampleFormats(): Array<Format!>?

Returns the sample Formats for the tracks identified by the extractor, or null if the extractor has not finished identifying tracks.

fun init(
    trackOutputProvider: ChunkExtractor.TrackOutputProvider?,
    startTimeUs: Long,
    endTimeUs: Long
): Unit

Initializes the wrapper to output to TrackOutputs provided by the specified , and configures the extractor to receive data from a new chunk.

Parameters
`trackOutputProvider: ChunkExtractor.TrackOutputProvider?`	The provider of `TrackOutput`s that will receive sample data.
`startTimeUs: Long`	The start position in the new chunk, or `TIME_UNSET` to output samples from the start of the chunk.
`endTimeUs: Long`	The end position in the new chunk, or `TIME_UNSET` to output samples to the end of the chunk.

fun read(input: ExtractorInput!): Boolean

Reads from the given ExtractorInput.

Parameters
`input: ExtractorInput!`	The input to read from.

Returns
`Boolean`	Whether there is any data left to extract. Returns false if the end of input has been reached.

Throws
`java.io.IOException`	If an error occurred reading from or parsing the input.

fun release(): Unit

Releases any held resources.
