Comment:

 Yes, mkvtoolnix should be updated to the latest version. I also wanted to
 update its dependencies libebml and libmatroska, but both of them changed
 their build systems from autotools to cmake. This inadvertently caused
 their library versions to change. I [https://github.com/Matroska-
 Org/libebml/issues/40 reported the problem to the developers] and although
 they made an attempt at fixing it, it was unsuccessful, and they were
 unwilling to invest further time into the issue. It seemed to me that
 cmake does not offer sufficient variables to allow a developer to fully
 specify the library versioning information. So when we update those two,
 we'll also have to increase the revision of anything linking with them, to
 rebuild them.
