Public constructors
MediaParserExtractorAdapter(playerId: PlayerId!) This function is deprecated. Use MediaParserExtractorAdapter.Factory instead.

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.

Constants

FACTORY

const val FACTORY: ProgressiveMediaExtractor.Factory!

This property is deprecated.

Use MediaParserExtractorAdapter.Factory instead.

Public constructors

MediaParserExtractorAdapter

MediaParserExtractorAdapter(playerId: PlayerId!)

This function is deprecated.

Use MediaParserExtractorAdapter.Factory instead.

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.
