MkvScanner provides an API for scanning Blu-ray directories and container files (such as MKVs), and for demuxing tracks from them as well.
The interface FileScanner defines the API. The available implementation is Eac3toScanner, which is a wrapper for the Windows tool eac3to.exe, and requires the executable to function.
FileScanner scanner = new Eac3toScanner("c:\\Program Files\\eac3to\\eac3to.exe", "c:\\demuxedTracks");
Video metadata = scanner.scanAndParseFile(new File("c:\\mkvs\\MyMovie.mkv"));
metadata now contains a list of the tracks found in the mkv file. Each track object (in metadata.getTracks()) contains information about the track, such as:
- name: plaintext label, if it has one
- format name: (AC-3, H-264, PGS, etc)
- format type: (Audio, Video, Subtitles, Chapters)
- language
scanner.demuxFileByTracks(new File("c:\\mkvs\\MyMovie.mkv"), Arrays.asList(1, 2, 3));
// demuxes only the first three tracks
scanner.demuxFileByLanguages(new File("c:\\mkvs\\MyMovie.mkv"), Arrays.asList("English", "Spanish", "Japanese"));
// demuxes all tracks in the video with the matching languages
demuxed tracks are output into the directory specified in the Eac3toScanner constructor
