                      long chunkIndex)

Parameters:

dataSource - The source from which the data should be loaded.

dataSpec - Defines the data to be loaded.

trackFormat - See Chunk.trackFormat.

trackSelectionReason - See Chunk.trackSelectionReason.

trackSelectionData - See Chunk.trackSelectionData.

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

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

Parameters:

output - The output that will receive the loaded media samples.

getFirstSampleIndex

public final int getFirstSampleIndex(int trackIndex)

Returns the index of the first sample in the specified track of the output that will originate from this chunk.

getOutput

protected final BaseMediaChunkOutput getOutput()

Returns the output most recently passed to init(BaseMediaChunkOutput).
