AdtsReader

Kotlin |Java

@UnstableApi
public final class AdtsReader implements ElementaryStreamReader

Parses a continuous ADTS byte stream and extracts individual frames.

Summary

Public fields
`long`	`sampleDurationUs`

Public constructors
`AdtsReader(boolean exposeId3)`
`AdtsReader( boolean exposeId3, @Nullable String language, @C.RoleFlags int roleFlags )`

Public methods
`void`	`consume(ParsableByteArray data)` Consumes (possibly partial) data from the current packet.
`void`	`createTracks( ExtractorOutput extractorOutput, TsPayloadReader.TrackIdGenerator idGenerator )` Initializes the reader by providing outputs and ids for the tracks.
`long`	`getSampleDurationUs()` Returns the duration in microseconds per sample, or `TIME_UNSET` if the sample duration is not available.
`static boolean`	`isAdtsSyncWord(int candidateSyncWord)` Returns whether an integer matches an ADTS SYNC word.
`void`	`packetFinished(boolean isEndOfInput)` Called when a packet ends.
`void`	`packetStarted(long pesTimeUs, @TsPayloadReader.Flags int flags)` Called when a packet starts.
`void`	`seek()` Notifies the reader that a seek has occurred.

public long sampleDurationUs

public AdtsReader(boolean exposeId3)

Parameters
`boolean exposeId3`	True if the reader should expose ID3 information.

public AdtsReader(
    boolean exposeId3,
    @Nullable String language,
    @C.RoleFlags int roleFlags
)

Parameters
`boolean exposeId3`	True if the reader should expose ID3 information.
`@Nullable String language`	Track language.
`@C.RoleFlags int roleFlags`	Track role flags.

public void consume(ParsableByteArray data)

Consumes (possibly partial) data from the current packet.

Parameters
`ParsableByteArray data`	The data to consume.

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

public void createTracks(
    ExtractorOutput extractorOutput,
    TsPayloadReader.TrackIdGenerator idGenerator
)

Initializes the reader by providing outputs and ids for the tracks.

Parameters
`ExtractorOutput extractorOutput`	The `ExtractorOutput` that receives the extracted data.
`TsPayloadReader.TrackIdGenerator idGenerator`	A `PesReader.TrackIdGenerator` that generates unique track ids for the `TrackOutput`s.

public long getSampleDurationUs()

Returns the duration in microseconds per sample, or TIME_UNSET if the sample duration is not available.

public static boolean isAdtsSyncWord(int candidateSyncWord)

Returns whether an integer matches an ADTS SYNC word.

public void packetFinished(boolean isEndOfInput)

Called when a packet ends.

public void packetStarted(long pesTimeUs, @TsPayloadReader.Flags int flags)

Called when a packet starts.

Parameters
`long pesTimeUs`	The timestamp associated with the packet.
`@TsPayloadReader.Flags int flags`	See `TsPayloadReader.Flags`.

public void seek()

Notifies the reader that a seek has occurred.
