How to Install MKVToolNix 9.9.0 on Ubuntu 16.04, 16.10

     MKVtoolnix is a set of tools to create, alter, split, join and inspect Matroska files(mkv). With these tools one can get information about (mkvinfo) Matroska files, extract tracks/data from (mkvextract) Matroska files and create (mkvmerge) Matroska files from other media files. Matroska is a multimedia file format aiming to become THE new container format for the future. Use MKVCleaver or gMKVExtractGUI to extract/demultiplex mkv video and audio files.

MKVToolNix 9.9.0 changelog

• GUI: chapter editor: added a character set selection in the preferences for text files. If a character set is selected there, it will be used instead of asking the user when opening text chapter files.
• GUI: multiplexer: added a column "character set" to the "tracks, chapters and tags" list view showing the currently selected character set for that track.
• mkvmerge: added an --engage option "all_i_slices_are_key_frames" for treating all I slices of an h.264/AVC stream as key frames in pathological streams that lack real key frames.
• GUI: running programs after jobs: added a new variable <MTX_INSTALLATION_DIRECTORY> for the directory the MKVToolNix GUI executable is located in.
• mkvmerge: DVB subtitle tracks whose CodecPrivate data is only four bytes long will now be fixed up to the proper five bytes by adding the subtitling type byte.
• mkvmerge: MP4 reader: "ctts" version 1 atoms are now supported.
• See changelog for more details
