Known direct subclasses

BaseMediaChunk, FakeMediaChunk

`BaseMediaChunk`	A base implementation of `MediaChunk` that outputs to a `BaseMediaChunkOutput`.
`FakeMediaChunk`	Fake `MediaChunk`.

Known indirect 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.

An abstract base class for Chunks that contain media samples.
