`final long`	`loadTaskId` Identifies the load task for this loadable.
`final long`	`startTimeUs` The start time of the media contained by the chunk, or `TIME_UNSET` if the data being loaded does not contain media samples.

Public constructors

SingleSampleMediaChunk

Parameters

`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 chunkIndex`	The index of the chunk, or `INDEX_UNSET` if it is not known.
`@C.TrackType int trackType`	The `track type` of the chunk.
`Format sampleFormat`	The `Format` of the sample in the chunk.

Public methods

cancelLoad

public 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 ).

isLoadCompleted

public boolean isLoadCompleted()

Returns whether the chunk has been fully loaded.

load

public void load()

Performs the load, returning on completion or cancellation.

Throws
`java.io.IOException`	If the input could not be loaded.
