[TrackOutputProvider](/reference/androidx/media3/exoplayer/source/chunk/ChunkExtractor.TrackOutputProvider) that provides [TrackOutputs](/reference/androidx/media3/extractor/TrackOutput) based on a predefined mapping from track type to output. |\n| [BundledChunkExtractor](/reference/androidx/media3/exoplayer/source/chunk/BundledChunkExtractor) | [ChunkExtractor](/reference/androidx/media3/exoplayer/source/chunk/ChunkExtractor) implementation that uses ExoPlayer app-bundled [Extractors](/reference/androidx/media3/extractor/Extractor). |\n| [BundledChunkExtractor.Factory](/reference/androidx/media3/exoplayer/source/chunk/BundledChunkExtractor.Factory) | [ChunkExtractor.Factory](/reference/androidx/media3/exoplayer/source/chunk/ChunkExtractor.Factory) for [BundledChunkExtractor](/reference/androidx/media3/exoplayer/source/chunk/BundledChunkExtractor). |\n| [Chunk](/reference/androidx/media3/exoplayer/source/chunk/Chunk) | An abstract base class for [Loadable](/reference/androidx/media3/exoplayer/upstream/Loader.Loadable) implementations that load chunks of data required for the playback of streams. |\n| [ChunkHolder](/reference/androidx/media3/exoplayer/source/chunk/ChunkHolder) | Holds a chunk or an indication that the end of the stream has been reached. |\n| [ChunkSampleStream](/reference/androidx/media3/exoplayer/source/chunk/ChunkSampleStream) | A [SampleStream](/reference/androidx/media3/exoplayer/source/SampleStream) that loads media in [Chunk](/reference/androidx/media3/exoplayer/source/chunk/Chunk)s, obtained from a [ChunkSource](/reference/androidx/media3/exoplayer/source/chunk/ChunkSource). |\n| [ChunkSampleStream.EmbeddedSampleStream](/reference/androidx/media3/exoplayer/source/chunk/ChunkSampleStream.EmbeddedSampleStream) | A [SampleStream](/reference/androidx/media3/exoplayer/source/SampleStream) embedded in a [ChunkSampleStream](/reference/androidx/media3/exoplayer/source/chunk/ChunkSampleStream). |\n| [ContainerMediaChunk](/reference/androidx/media3/exoplayer/source/chunk/ContainerMediaChunk) | A [BaseMediaChunk](/reference/androidx/media3/exoplayer/source/chunk/BaseMediaChunk) that uses an [Extractor](/reference/androidx/media3/extractor/Extractor) to decode sample data. |\n| [DataChunk](/reference/androidx/media3/exoplayer/source/chunk/DataChunk) | A base class for [Chunk](/reference/androidx/media3/exoplayer/source/chunk/Chunk) implementations where the data should be loaded into a ` byte[]` before being consumed. |\n| [InitializationChunk](/reference/androidx/media3/exoplayer/source/chunk/InitializationChunk) | A [Chunk](/reference/androidx/media3/exoplayer/source/chunk/Chunk) that uses an [Extractor](/reference/androidx/media3/extractor/Extractor) to decode initialization data for single track. |\n| [MediaChunk](/reference/androidx/media3/exoplayer/source/chunk/MediaChunk) | An abstract base class for [Chunk](/reference/androidx/media3/exoplayer/source/chunk/Chunk)s that contain media samples. |\n| [MediaParserChunkExtractor](/reference/androidx/media3/exoplayer/source/chunk/MediaParserChunkExtractor) | [ChunkExtractor](/reference/androidx/media3/exoplayer/source/chunk/ChunkExtractor) implemented on top of the platform's [MediaParser](https://developer.android.com/reference/android/media/MediaParser.html). |\n| [MediaParserChunkExtractor.Factory](/reference/androidx/media3/exoplayer/source/chunk/MediaParserChunkExtractor.Factory) | A [ChunkExtractor.Factory](/reference/androidx/media3/exoplayer/source/chunk/ChunkExtractor.Factory) for
