MKVToolNix is a set of tools to create, alter, modify and inspect Matroska files under Linux, other Unices and Windows. They do for Matroska what the OGMtools do for the OGM format and then some. MKVToolNix package contains 2 main programs: mkvmerge and mkvmerge GUI (or just mmg) which created by Moritz Bunkus. mkvmerge can read a lot of different multimedia files and put their contents into Matroska files. Unfortunately this is a command line program, and not everyone is comfortable working on the command line. This is where mkvmerge GUI comes into play. It is a GUI that provides the user with an intuitive but powerful interface to mkvmerge. Both programs are available for both Windows and GNU/Linux and other Unix derivatives. mkvtoolnix v7.3.0 implements support for PCM in MPEG program (.vob – DVDs) and transport streams (.ts, .m2ts – Blu-rays, television broadcasts) as well as for teletext subtitles in MPEG tranport streams. Apart from that a lot of work has gone into the new GUI.
