Known direct subclasses

ContainerMediaChunk, SingleSampleMediaChunk

`ContainerMediaChunk`	A `BaseMediaChunk` that uses an `Extractor` to decode sample data.
`SingleSampleMediaChunk`	A `BaseMediaChunk` for chunks consisting of a single raw sample.

A base implementation of MediaChunk that outputs to a BaseMediaChunkOutput.

Summary

Public constructors
`BaseMediaChunk( dataSource: DataSource!, dataSpec: DataSpec!, trackFormat: Format!, @C.SelectionReason trackSelectionReason: Int, trackSelectionData: Any?, startTimeUs: Long, endTimeUs: Long, clippedStartTimeUs: Long, clippedEndTimeUs: Long, chunkIndex: Long )`

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.

Protected properties
`@MonotonicNonNull BaseMediaChunkOutput!`	`@MonotonicNonNull output`
