• Working with metadata in Matroska (MKV) files

This example demonstrates how to extract subtitles from an MKV video.

 try (Metadata metadata = new Metadata(Constants.MkvWithSubtitles)) {
     MatroskaRootPackage root = metadata.getRootPackageGeneric();
     for (MatroskaSubtitleTrack subtitleTrack : root.getMatroskaPackage().getSubtitleTracks()) {
         System.out.println(subtitleTrack.getLanguageIetf() != null ? subtitleTrack.getLanguageIetf() : subtitleTrack.getLanguage());
         for (MatroskaSubtitle subtitle : subtitleTrack.getSubtitles()) {
             System.out.println(String.format("Timecode=%s, Duration=%s", subtitle.getTimecode(), subtitle.getDuration()));
             System.out.println(subtitle.getText());
         }
     }
