H264Reader

Kotlin |Java

@UnstableApi
public final class H264Reader implements ElementaryStreamReader

Parses a continuous H264 byte stream and extracts individual frames.

Summary

Public constructors
`H264Reader( SeiReader seiReader, boolean allowNonIdrKeyframes, boolean detectAccessUnits )`

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`	`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 H264Reader(
    SeiReader seiReader,
    boolean allowNonIdrKeyframes,
    boolean detectAccessUnits
)

Parameters
`SeiReader seiReader`	An SEI reader for consuming closed caption channels.
`boolean allowNonIdrKeyframes`	Whether to treat samples consisting of non-IDR I slices as synchronization samples (key-frames).
`boolean detectAccessUnits`	Whether to split the input stream into access units (samples) based on slice headers. Pass `false` if the stream contains access unit delimiters (AUDs).

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 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.
