Artifact: androidx.media3:media3-extractor

Kotlin |Java

@UnstableApi
public final class SectionReader implements TsPayloadReader

Reads section data packets and feeds the whole sections to a given SectionPayloadReader. Useful information on PSI sections can be found in ISO/IEC 13818-1, section 2.4.4.

Summary

Public constructors
`SectionReader(SectionPayloadReader reader)`

Public methods
`void`	`consume(ParsableByteArray data, @TsPayloadReader.Flags int flags)` Consumes the payload of a TS packet.
`void`	`init( TimestampAdjuster timestampAdjuster, ExtractorOutput extractorOutput, TsPayloadReader.TrackIdGenerator idGenerator )` Initializes the payload reader.
`void`	`seek()` Notifies the reader that a seek has occurred.

Inherited Constants

From androidx.media3.extractor.ts.TsPayloadReader

`static final int`	`FLAG_DATA_ALIGNMENT_INDICATOR = 4` Indicates the presence of the data_alignment_indicator in the PES header.
`static final int`	`FLAG_PAYLOAD_UNIT_START_INDICATOR = 1` Indicates the presence of the payload_unit_start_indicator in the TS packet header.
`static final int`	`FLAG_RANDOM_ACCESS_INDICATOR = 2` Indicates the presence of the random_access_indicator in the TS packet header adaptation field.

SectionReader

public SectionReader(SectionPayloadReader reader)

Public methods

consume

public void consume(ParsableByteArray data, @TsPayloadReader.Flags int flags)

Consumes the payload of a TS packet.

Parameters
`ParsableByteArray data`	The TS packet. The position will be set to the start of the payload.
`@TsPayloadReader.Flags int flags`	See `Flags`.

Throws
`androidx.media3.common.ParserException`	If the payload could not be parsed.

init

public void init(
    TimestampAdjuster timestampAdjuster,
    ExtractorOutput extractorOutput,
    TsPayloadReader.TrackIdGenerator idGenerator
)

Initializes the payload reader.

Parameters
`TimestampAdjuster timestampAdjuster`	A timestamp adjuster for offsetting and scaling sample timestamps.
`ExtractorOutput extractorOutput`	The `ExtractorOutput` that receives the extracted data.
`TsPayloadReader.TrackIdGenerator idGenerator`	A `PesReader.TrackIdGenerator` that generates unique track ids for the `TrackOutput`s.

seek

public void seek()

Notifies the reader that a seek has occurred.

Following a call to this method, the data passed to the next invocation of consume will not be a continuation of the data that was previously passed. Hence the reader should reset any internal state.
