SubtitleTranscodingExtractorOutput
@UnstableApi
class SubtitleTranscodingExtractorOutput : ExtractorOutput
A wrapping ExtractorOutput that transcodes text samples from supported subtitle formats to APPLICATION_MEDIA3_CUES.
The resulting APPLICATION_MEDIA3_CUES samples are emitted to the underlying TrackOutput.
For non-text tracks (i.e. where C.TrackType is not C.TRACK_TYPE_TEXT), samples are passed through to the underlying TrackOutput without modification.
Support for subtitle formats is determined by supportsFormat on the SubtitleParser.Factory passed to the constructor of this class.
