H264Reader

Kotlin |Java

@UnstableApi
class H264Reader : ElementaryStreamReader

Parses a continuous H264 byte stream and extracts individual frames.

Summary

Public constructors
`H264Reader( seiReader: SeiReader!, allowNonIdrKeyframes: Boolean, detectAccessUnits: Boolean )`

Public functions
`Unit`	`consume(data: ParsableByteArray!)` Consumes (possibly partial) data from the current packet.
`Unit`	`createTracks( extractorOutput: ExtractorOutput!, idGenerator: TsPayloadReader.TrackIdGenerator! )` Initializes the reader by providing outputs and ids for the tracks.
`Unit`	`packetFinished()` Called when a packet ends.
`Unit`	`packetStarted(pesTimeUs: Long, @TsPayloadReader.Flags flags: Int)` Called when a packet starts.
`Unit`	`seek()` Notifies the reader that a seek has occurred.

H264Reader(
    seiReader: SeiReader!,
    allowNonIdrKeyframes: Boolean,
    detectAccessUnits: Boolean
)

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

fun consume(data: ParsableByteArray!): Unit

Consumes (possibly partial) data from the current packet.

Parameters
`data: ParsableByteArray!`	The data to consume.

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

fun createTracks(
    extractorOutput: ExtractorOutput!,
    idGenerator: TsPayloadReader.TrackIdGenerator!
): Unit

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

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

fun packetFinished(): Unit

Called when a packet ends.

fun packetStarted(pesTimeUs: Long, @TsPayloadReader.Flags flags: Int): Unit

Called when a packet starts.

Parameters
`pesTimeUs: Long`	The timestamp associated with the packet.
`@TsPayloadReader.Flags flags: Int`	See `TsPayloadReader.Flags`.

fun seek(): Unit

Notifies the reader that a seek has occurred.
