Ac4Reader

Kotlin |Java

@UnstableApi
public final class Ac4Reader implements ElementaryStreamReader

Parses a continuous AC-4 byte stream and extracts individual samples.

Summary

Public constructors
`Ac4Reader(String containerMimeType)` Constructs a new reader for AC-4 elementary streams.
`Ac4Reader( @Nullable String language, @C.RoleFlags int roleFlags, String containerMimeType )` Constructs a new reader for AC-4 elementary streams.

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.
`void`	`packetStarted(long pesTimeUs, @TsPayloadReader.Flags int flags)` Called when a packet starts.
`void`	`seek()` Notifies the reader that a seek has occurred.

`void`	`endOfInputReached()` Called when there will be no further packets (unless a seek occurs) because the stream ended.
`void`	`packetFinished()` Called when a PES packet ends.

public Ac4Reader(String containerMimeType)

Constructs a new reader for AC-4 elementary streams.

Parameters
`String containerMimeType`	The MIME type of the container holding the stream.

public Ac4Reader(
    @Nullable String language,
    @C.RoleFlags int roleFlags,
    String containerMimeType
)

Constructs a new reader for AC-4 elementary streams.

Parameters
`@Nullable String language`	Track language.
`@C.RoleFlags int roleFlags`	Track role flags.
`String containerMimeType`	The MIME type of the container holding the stream.

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 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.
