TsExtractor(
    @DefaultTsPayloadReaderFactory.Flags defaultTsPayloadReaderFlags: Int

TsExtractor

TsExtractor(subtitleParserFactory: SubtitleParser.Factory!)

Parameters
subtitleParserFactory: SubtitleParser.Factory!

The SubtitleParser.Factory for parsing subtitles during extraction.

TsExtractor

TsExtractor(
    @TsExtractor.Flags extractorFlags: Int,
    subtitleParserFactory: SubtitleParser.Factory!
)

Constructs an instance.

Parameters
@TsExtractor.Flags extractorFlags: Int

Flags that control the extractor's behavior.
subtitleParserFactory: SubtitleParser.Factory!

The SubtitleParser.Factory for parsing subtitles during extraction.

    payloadReaderFactory: TsPayloadReader.Factory!,
    timestampSearchBytes: Int
)

Constructs an instance.

Parameters
@TsExtractor.Mode mode: Int

Mode for the extractor. One of MODE_MULTI_PMT, MODE_SINGLE_PMT and MODE_HLS.
@TsExtractor.Flags extractorFlags: Int

Flags that control the extractor's behavior.
subtitleParserFactory: SubtitleParser.Factory!

The SubtitleParser.Factory for parsing subtitles during extraction.
timestampAdjuster: TimestampAdjuster!

A timestamp adjuster for offsetting and scaling sample timestamps.
payloadReaderFactory: TsPayloadReader.Factory!

Factory for injecting a custom set of payload readers.
timestampSearchBytes: Int

The number of bytes searched from a given position in the stream to find a PCR timestamp. If this value is too small, the duration might be unknown and seeking might not be supported for high bitrate progressive streams. Setting a large value for this field might be inefficient though because the extractor stores a buffer of timestampSearchBytes bytes when determining the duration or when performing a seek operation. The default value is DEFAULT_TIMESTAMP_SEARCH_BYTES. If the number of bytes left in the stream from the current position is less than timestampSearchBytes, the search is performed on the bytes left.

Public functions

init

fun init(output: ExtractorOutput!): Unit

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

Parameters
output: ExtractorOutput!

An ExtractorOutput to receive extracted data.

newFactory

java-static fun newFactory(subtitleParserFactory: SubtitleParser.Factory!): ExtractorsFactory!

Creates a factory for TsExtractor instances with the provided SubtitleParser.Factory.

read

@Extractor.ReadResult
fun read(input: ExtractorInput!, seekPosition: PositionHolder!): Int

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.

In the common case, RESULT_CONTINUE is returned to indicate that the ExtractorInput passed to the next read is required to provide data continuing from the position in the stream reached by the returning call. If the extractor requires data to be provided from a different position, then that position is set in seekPosition and RESULT_SEEK is returned. If the extractor reached the end of the data provided by the ExtractorInput, then RESULT_END_OF_INPUT is returned.

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
input: ExtractorInput!

The ExtractorInput from which data should be read.
seekPosition: PositionHolder!

If RESULT_SEEK is returned, this holder is updated to hold the position of the required data.
Returns
Int

One of the RESULT_ values defined in this interface.
Throws
java.io.IOException

If an error occurred reading from or parsing the input.

release

fun release(): Unit

Releases all kept resources.

seek

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

Notifies the extractor that a seek has occurred.

Following a call to this method, the ExtractorInput passed to the next invocation of read is required to provide data starting from position in the stream. Valid random access positions are the start of the stream and positions that can be obtained from any SeekMap passed to the ExtractorOutput.

Parameters
position: Long

The byte offset in the stream from which data will be provided.
timeUs: Long

The seek time in microseconds.

sniff

fun sniff(input: ExtractorInput!): Boolean

Returns whether this extractor can extract samples from the ExtractorInput, which must provide data from the start of the stream.

If true is returned, the input's reading position may have been modified. Otherwise, only its peek position may have been modified.

Parameters
input: ExtractorInput!

The ExtractorInput from which data should be peeked/read.
Returns
Boolean

Whether this extractor can read the provided input.
Throws
java.io.IOException

If an error occurred reading from the input.
