Description copied from interface: HlsExtractorFactory

Creates an Extractor for extracting HLS media chunks.

Specified by:

createExtractor in interface HlsExtractorFactory

Parameters:

previousExtractor - A previously used Extractor which can be reused if the current chunk is a continuation of the previously extracted chunk, or null otherwise. It is the responsibility of implementers to only reuse extractors that are suited for reusage.

uri - The URI of the media chunk.

format - A Format associated with the chunk to extract.

muxedCaptionFormats - List of muxed caption Formats. Null if no closed caption information is available in the master playlist.

drmInitData - DrmInitData associated with the chunk.

timestampAdjuster - Adjuster corresponding to the provided discontinuity sequence number.

responseHeaders - The HTTP response headers associated with the media segment or initialization section to extract.

extractorInput - The first extractor input that will be passed to the returned extractor's Extractor.read(ExtractorInput, PositionHolder). Must only be used to call Extractor.sniff(ExtractorInput).

Returns:

A pair containing the Extractor and a boolean that indicates whether it is a packed audio extractor. The first element may be previousExtractor if the factory has determined it can be re-used.

Throws:

java.lang.InterruptedException - If the thread is interrupted while sniffing.

java.io.IOException - If an I/O error is encountered while sniffing.
