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 functions
Int	getFirstSampleIndex(trackIndex: Int) Returns the index of the first sample in the specified track of the output that will originate from this chunk.
Unit	init(output: BaseMediaChunkOutput!) Initializes the chunk for loading, setting the BaseMediaChunkOutput that will receive samples as they are loaded.

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