Known direct subclasses

ContainerMediaChunk, SingleSampleMediaChunk

ContainerMediaChunk	A BaseMediaChunk that uses an Extractor to decode sample data.
SingleSampleMediaChunk	This class is deprecated. The only use for this class is subtitle playback, but it is only compatible with legacy subtitle decoding, which is not supported by default.

---

A base implementation of MediaChunk that outputs to a BaseMediaChunkOutput.

Summary

Public fields
final long	clippedEndTimeUs The time from which output will end, or TIME_UNSET if output will end at the end of the chunk.
final long	clippedStartTimeUs The time from which output will begin, or TIME_UNSET if output will begin from the start of the chunk.

Protected fields

Public methods
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.
void	init(BaseMediaChunkOutput output) Initializes the chunk for loading, setting the BaseMediaChunkOutput that will receive samples as they are loaded.

Protected methods
final BaseMediaChunkOutput	getOutput() Returns the output most recently passed to init.

Inherited fields
