Format[]	getSampleFormats() Returns the sample Formats most recently output by the extractor, or null.
SeekMap	getSeekMap() Returns the SeekMap most recently output by the extractor, or null.
void	init(ChunkExtractorWrapper.TrackOutputProvider trackOutputProvider, long startTimeUs, long endTimeUs) Initializes the wrapper to output to TrackOutputs provided by the specified ChunkExtractorWrapper.TrackOutputProvider, and configures the extractor to receive data from a new chunk.
void	seekMap(SeekMap seekMap) Called when a SeekMap has been extracted from the stream.
TrackOutput	track(int id, int type) Called by the Extractor to get the TrackOutput for a specific track.

                             Format primaryTrackManifestFormat)

Parameters:

extractor - The extractor to wrap.

primaryTrackType - The type of the primary track. Typically one of the C TRACK_TYPE_* constants.

primaryTrackManifestFormat - A manifest defined Format whose data should be merged into any sample Format output from the Extractor for the primary track.

Method Detail

getSeekMap

public SeekMap getSeekMap()

Returns the SeekMap most recently output by the extractor, or null.

getSampleFormats

public Format[] getSampleFormats()

Returns the sample Formats most recently output by the extractor, or null.

init

public void init(@Nullable
                 ChunkExtractorWrapper.TrackOutputProvider trackOutputProvider,
                 long startTimeUs,
                 long endTimeUs)

Initializes the wrapper to output to TrackOutputs provided by the specified ChunkExtractorWrapper.TrackOutputProvider, and configures the extractor to receive data from a new chunk.

Parameters:

trackOutputProvider - The provider of TrackOutputs that will receive sample data.

startTimeUs - The start position in the new chunk, or C.TIME_UNSET to output samples from the start of the chunk.

endTimeUs - The end position in the new chunk, or C.TIME_UNSET to output samples to the end of the chunk.

track

public TrackOutput track(int id,
                         int type)

Description copied from interface: ExtractorOutput

Called by the Extractor to get the TrackOutput for a specific track.

The same TrackOutput is returned if multiple calls are made with the same id.

Specified by:

track in interface ExtractorOutput

Parameters:

id - A track identifier.

type - The type of the track. Typically one of the C TRACK_TYPE_* constants.

Returns:

The TrackOutput for the given track identifier.

endTracks

public void endTracks()

Description copied from interface: ExtractorOutput

Called when all tracks have been identified, meaning no new trackId values will be passed to ExtractorOutput.track(int, int).

Specified by:

endTracks in interface ExtractorOutput

seekMap

public void seekMap(SeekMap seekMap)

Description copied from interface: ExtractorOutput

Called when a SeekMap has been extracted from the stream.

Specified by:

seekMap in interface ExtractorOutput

Parameters:

seekMap - The extracted SeekMap.
