Public functions

format

fun format(format: Format!): Unit

Called when the Format of the track has been extracted from the stream.

Parameters
format: Format!

The extracted Format.

sampleData

fun sampleData(data: ParsableByteArray!, length: Int): Unit

Equivalent to sampleData sampleData(data, length, SAMPLE_DATA_PART_MAIN)}.

sampleData

fun sampleData(
    data: ParsableByteArray!,
    length: Int,
    @TrackOutput.SampleDataPart sampleDataPart: Int
): Unit

Called to write sample data to the output.

Parameters
data: ParsableByteArray!

A ParsableByteArray from which to read the sample data.

length: Int

The number of bytes to read, starting from data.getPosition().

@TrackOutput.SampleDataPart sampleDataPart: Int

The part of the sample data to which this call corresponds.

sampleData

fun sampleData(input: DataReader!, length: Int, allowEndOfInput: Boolean): Int

Equivalent to sampleData(input, length, allowEndOfInput, SAMPLE_DATA_PART_MAIN).

sampleData

fun sampleData(
    input: DataReader!,
    length: Int,
    allowEndOfInput: Boolean,
    @TrackOutput.SampleDataPart sampleDataPart: Int
): Int

Called to write sample data to the output.

Parameters
input: DataReader!

A DataReader from which to read the sample data.

length: Int

The maximum length to read from the input.

allowEndOfInput: Boolean

True if encountering the end of the input having read no data is allowed, and should result in RESULT_END_OF_INPUT being returned. False if it should be considered an error, causing an EOFException to be thrown.

@TrackOutput.SampleDataPart sampleDataPart: Int

The part of the sample data to which this call corresponds.

Returns
Int

The number of bytes appended.

Throws
java.io.IOException

If an error occurred reading from the input.

sampleMetadata

fun sampleMetadata(
    timeUs: Long,
    @C.BufferFlags flags: Int,
    size: Int,
    offset: Int,
    cryptoData: TrackOutput.CryptoData?
): Unit

Called when metadata associated with a sample has been extracted from the stream.

The corresponding sample data will have already been passed to the output via calls to sampleData or sampleData.

Parameters
timeUs: Long

The media timestamp associated with the sample, in microseconds.

@C.BufferFlags flags: Int

Flags associated with the sample. See C.BUFFER_FLAG_*.

size: Int

The size of the sample data, in bytes.

offset: Int

The number of bytes that have been passed to sampleData or sampleData since the last byte belonging to the sample whose metadata is being passed.

cryptoData: TrackOutput.CryptoData?

The encryption data required to decrypt the sample. May be null.
