Vunio is a native macOS and iPhone video player for the files other players tend to give up on. It opens MKV and other tricky formats, browses SMB, NFS, SFTP, FTP and WebDAV shares without mounting them, and matches subtitles to the video itself. The public beta is especially focused on subtitle rendering, Simplified Chinese and ASS/SSA support, and remembering downloaded subtitles when you reopen a film.
