BundledHlsMediaChunkExtractor


@UnstableApi
class BundledHlsMediaChunkExtractor : HlsMediaChunkExtractor


HlsMediaChunkExtractor implementation that uses ExoPlayer app-bundled Extractors.

Summary

Public constructors

BundledHlsMediaChunkExtractor(
    extractor: Extractor!,
    multivariantPlaylistFormat: Format!,
    timestampAdjuster: TimestampAdjuster!
)

Creates a new instance.

Public functions

Unit
init(extractorOutput: ExtractorOutput!)

Initializes the extractor with an ExtractorOutput.

Boolean

Returns whether this is a packed audio extractor, as defined in RFC 8216, Section 3.4.

Boolean

Returns whether this instance can be used for extracting multiple continuous segments.

Unit

Resets the sample parsing state.

Boolean
read(extractorInput: ExtractorInput!)

Extracts data read from a provided ExtractorInput.

HlsMediaChunkExtractor!

Returns a new instance for extracting the same type of media as this one.

Public constructors

BundledHlsMediaChunkExtractor

BundledHlsMediaChunkExtractor(
    extractor: Extractor!,
    multivariantPlaylistFormat: Format!,
    timestampAdjuster: TimestampAdjuster!
)

Creates a new instance.

Parameters
extractor: Extractor!

The underlying Extractor.

multivariantPlaylistFormat: Format!

The Format obtained from the multivariant playlist.

timestampAdjuster: TimestampAdjuster!

A TimestampAdjuster to adjust sample timestamps.

Public functions

init

fun init(extractorOutput: ExtractorOutput!): Unit

Initializes the extractor with an ExtractorOutput. Called at most once.

Parameters
extractorOutput: ExtractorOutput!

An ExtractorOutput to receive extracted data.

isPackedAudioExtractor

fun isPackedAudioExtractor(): Boolean

Returns whether this is a packed audio extractor, as defined in RFC 8216, Section 3.4.

isReusable

fun isReusable(): Boolean

Returns whether this instance can be used for extracting multiple continuous segments.

onTruncatedSegmentParsed

fun onTruncatedSegmentParsed(): Unit

Resets the sample parsing state.

Resetting the parsing state allows support for Fragmented MP4 EXT-X-I-FRAME-STREAM-INF segments. EXT-X-I-FRAME-STREAM-INF segments are truncated to include only a leading key frame. After parsing said keyframe, an extractor may reach an unexpected end of file. By resetting its state, we can continue feeding samples from the following segments to the extractor. See #7512 for context.

read

fun read(extractorInput: ExtractorInput!): Boolean

Extracts data read from a provided ExtractorInput. Must not be called before init.

A single call to this method will block until some progress has been made, but will not block for longer than this. Hence each call will consume only a small amount of input data.

When this method throws an IOException, extraction may continue by providing an ExtractorInput with an unchanged read position to a subsequent call to this method.

Parameters
extractorInput: 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.

recreate

fun recreate(): HlsMediaChunkExtractor!

Returns a new instance for extracting the same type of media as this one. Can only be called on instances that are not reusable.
