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

Parameters
Format format

The extracted Format.

sampleData

public void sampleData(
    ParsableByteArray data,
    int length,
    @TrackOutput.SampleDataPart int sampleDataPart
)

Called to write sample data to the output.

Parameters
ParsableByteArray data

A ParsableByteArray from which to read the sample data.
int length

The number of bytes to read, starting from data.getPosition().
@TrackOutput.SampleDataPart int sampleDataPart

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

sampleData

public int sampleData(
    DataReader input,
    int length,
    boolean allowEndOfInput,
    @TrackOutput.SampleDataPart int sampleDataPart
)

Called to write sample data to the output.

Parameters
DataReader input

A DataReader from which to read the sample data.
int length

The maximum length to read from the input.
boolean allowEndOfInput

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 int sampleDataPart

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

public void sampleMetadata(
    long timeUs,
    @C.BufferFlags int flags,
    int size,
    int offset,
    @Nullable TrackOutput.CryptoData cryptoData
)

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
long timeUs

The media timestamp associated with the sample, in microseconds.
@C.BufferFlags int flags

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

The size of the sample data, in bytes.
int offset

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.
@Nullable TrackOutput.CryptoData cryptoData

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