public ContainerMediaChunk(
    DataSource dataSource,

    Format trackFormat,
    @C.SelectionReason int trackSelectionReason,

Parameters
DataSource dataSource

The source from which the data should be loaded.

DataSpec dataSpec

Defines the data to be loaded.

Format trackFormat

See trackFormat.

@C.SelectionReason int trackSelectionReason

See trackSelectionReason.

@Nullable Object trackSelectionData

See trackSelectionData.

long startTimeUs

The start time of the media contained by the chunk, in microseconds.

long endTimeUs

The end time of the media contained by the chunk, in microseconds.

long clippedStartTimeUs

The time in the chunk from which output will begin, or TIME_UNSET to output from the start of the chunk.

long clippedEndTimeUs

The time in the chunk from which output will end, or TIME_UNSET to output to the end of the chunk.

long chunkIndex

The index of the chunk, or INDEX_UNSET if it is not known.

int chunkCount

The number of chunks in the underlying media that are spanned by this instance. Normally equal to one, but may be larger if multiple chunks as defined by the underlying media are being merged into a single load.

long sampleOffsetUs

An offset to add to the sample timestamps parsed by the extractor.

ChunkExtractor chunkExtractor

A wrapped extractor to use for parsing the data.

Public methods

cancelLoad

public final void cancelLoad()

Cancels the load.

Loadable implementations should ensure that a currently executing load call will exit reasonably quickly after this method is called. The load call may exit either by returning or by throwing an IOException.

If there is a currently executing load call, then the thread on which that call is being made will be interrupted immediately after the call to this method. Hence implementations do not need to (and should not attempt to) interrupt the loading thread themselves.

Although the loading thread will be interrupted, Loadable implementations should not use the interrupted status of the loading thread in load to determine whether the load has been canceled. This approach is not robust [Internal ref: b/79223737]. Instead, implementations should use their own flag to signal cancelation (for example, using ).

getNextChunkIndex

public long getNextChunkIndex()

Returns the next chunk index or INDEX_UNSET if it is not known.

isLoadCompleted

public boolean isLoadCompleted()

Returns whether the chunk has been fully loaded.

load

public final void load()

Performs the load, returning on completion or cancellation.

Throws
java.io.IOException

If the input could not be loaded.

Protected methods

getTrackOutputProvider

protected ChunkExtractor.TrackOutputProvider getTrackOutputProvider(BaseMediaChunkOutput baseMediaChunkOutput)

Returns the TrackOutputProvider to be used by the wrapped extractor.

Parameters
BaseMediaChunkOutput baseMediaChunkOutput

The BaseMediaChunkOutput most recently passed to init.

Returns
ChunkExtractor.TrackOutputProvider

A TrackOutputProvider to be used by the wrapped extractor.
