Constants

FACTORY

public static final ProgressiveMediaExtractor.Factory FACTORY

This field is deprecated.

Use MediaParserExtractorAdapter.Factory instead.

Public constructors

MediaParserExtractorAdapter

public MediaParserExtractorAdapter(PlayerId playerId)

This method is deprecated.

Use MediaParserExtractorAdapter.Factory instead.

Public methods

disableSeekingOnMp3Streams

public void disableSeekingOnMp3Streams()

Disables seeking in MP3 streams.

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

getCurrentInputPosition

public long getCurrentInputPosition()

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

init

public void init(
    DataReader dataReader,
    Uri uri,
    Map<String, List<String>> responseHeaders,
    long position,
    long length,
    ExtractorOutput output
)

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.
Map<String, List<String>> responseHeaders	The response headers of the media, or an empty map if there are none.
long position	The initial position of the dataReader in the stream.
long length	The length of the stream, or LENGTH_UNSET if length is unknown.
ExtractorOutput output	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

public int read(PositionHolder positionHolder)

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

public void release()

Releases any held resources.

seek

public void seek(long position, long seekTimeUs)

Notifies the extracting infrastructure that a seek has occurred.

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