ExoPlayer is unable to detect the presence of subtitle tracks in some MPEG-TS files that don't fully declare them. It's possible for a developer to provide the list instead, but doing so is quite awkward without this helper method. This is consistent for how `DefaultExtractorsFactory` allows other aspects of the delegate `Extractor` implementations to be customised. * Issue: google/ExoPlayer#10175 * Issue: google/ExoPlayer#10505 #minor-release PiperOrigin-RevId: 490214619 (cherry picked from commit 4853444f0dc90163c257d0e20962604510557df4)
