class BundledExtractorsAdapter : ProgressiveMediaExtractor

ProgressiveMediaExtractor built on top of Extractor instances, whose implementation classes are bundled in the app.

Summary

Public constructors
`BundledExtractorsAdapter(extractorsFactory: ExtractorsFactory!)` Creates a holder that will select an extractor and initialize it using the specified output.

Public functions
`Unit`	`disableSeekingOnMp3Streams()` Disables seeking in MP3 streams.
`Long`	`getCurrentInputPosition()` Returns the current read position in the input stream, or `INDEX_UNSET` if no input is available.
`Unit`	`init( dataReader: DataReader!, uri: Uri!, responseHeaders: (Mutable)Map<String!, (Mutable)List<String!>!>!, position: Long, length: Long, output: ExtractorOutput! )` Initializes the underlying infrastructure for reading from the input.
`Int`	`read(positionHolder: PositionHolder!)` Extracts data starting at the current input stream position.
`Unit`	`release()` Releases any held resources.
`Unit`	`seek(position: Long, seekTimeUs: Long)` Notifies the extracting infrastructure that a seek has occurred.

Public constructors

BundledExtractorsAdapter

BundledExtractorsAdapter(extractorsFactory: ExtractorsFactory!)

Creates a holder that will select an extractor and initialize it using the specified output.

Parameters
`extractorsFactory: ExtractorsFactory!`	The `ExtractorsFactory` providing the extractors to choose from.

Public functions

disableSeekingOnMp3Streams

fun disableSeekingOnMp3Streams(): Unit

Disables seeking in MP3 streams.

MP3 live streams commonly have seekable metadata, despite being unseekable.

getCurrentInputPosition

fun getCurrentInputPosition(): Long

Returns the current read position in the input stream, or INDEX_UNSET if no input is available.

init

fun init(
    dataReader: DataReader!,
    uri: Uri!,
    responseHeaders: (Mutable)Map<String!, (Mutable)List<String!>!>!,
    position: Long,
    length: Long,
    output: ExtractorOutput!
): Unit

Initializes the underlying infrastructure for reading from the input.

Parameters
`dataReader: DataReader!`	The `DataReader` from which data should be read.
`uri: Uri!`	The `Uri` from which the media is obtained.
`responseHeaders: (Mutable)Map<String!, (Mutable)List<String!>!>!`	The response headers of the media, or an empty map if there are none.
`position: Long`	The initial position of the `dataReader` in the stream.
`length: Long`	The length of the stream, or `LENGTH_UNSET` if length is unknown.
`output: ExtractorOutput!`	The `ExtractorOutput` that will be used to initialize the selected extractor.

Throws
`androidx.media3.exoplayer.source.UnrecognizedInputFormatException`	Thrown if the input format could not be detected.
`java.io.IOException`	Thrown if the input could not be read.

read

fun read(positionHolder: PositionHolder!): Int

Extracts data starting at the current input stream position.

Parameters
`positionHolder: PositionHolder!`	If `RESULT_SEEK` is returned, this holder is updated to hold the position of the required data.

Returns
`Int`	One of the `Extractor.RESULT_*` values.

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

release

fun release(): Unit

Releases any held resources.

seek

fun seek(position: Long, seekTimeUs: Long): Unit

Notifies the extracting infrastructure that a seek has occurred.

Parameters
`position: Long`	The byte offset in the stream from which data will be provided.
`seekTimeUs: Long`	The seek time in microseconds.
