ChunkExtractor.Factory

fun createProgressiveMediaExtractor(
    @C.TrackType primaryTrackType: Int,
    representationFormat: Format!,
    enableEventMessageTrack: Boolean,
    closedCaptionFormats: (Mutable)List<Format!>!,
    playerEmsgTrackOutput: TrackOutput?,
    playerId: PlayerId!
): ChunkExtractor?

Returns a new ChunkExtractor instance.

@CanIgnoreReturnValue
fun experimentalParseSubtitlesDuringExtraction(
    parseSubtitlesDuringExtraction: Boolean
): ChunkExtractor.Factory!

Sets whether subtitles should be parsed as part of extraction (before being added to the sample queue) or as part of rendering (when being taken from the sample queue). Defaults to false (i.e. subtitles will be parsed as part of rendering).

This method is experimental and will be renamed or removed in a future release.

fun getOutputTextFormat(sourceFormat: Format!): Format!

Returns the output Format of emitted text samples which were originally in sourceFormat.

In many cases, where an Extractor emits samples from the source without mutation, this method simply returns sourceFormat. In other cases, such as an Extractor that transcodes subtitles from the sourceFormat to APPLICATION_MEDIA3_CUES, the format is updated to indicate the transcoding that is taking place.

Non-text source formats are always returned without mutation.

@CanIgnoreReturnValue
fun setSubtitleParserFactory(subtitleParserFactory: SubtitleParser.Factory!): ChunkExtractor.Factory!

Sets the SubtitleParser.Factory to use for parsing subtitles during extraction. The default factory value is implementation dependent.
