0

Install MKVToolNix Matroska tools for Linux Ubuntu. MKVToolNix is a set of tools to create, alter and inspect Matroska files on Linux Systems. MKVToolNix Matroska is aiming to become the new standard media container format. These tools can work with Matroska files: mkvmerge creates Matroska files and mkvinfo lists information about them.

MKVToolNix 15

New features and enhancements

  • MKVToolNix GUI: multiplex tool: added a new entry to the “source files” context menu labeled “Set destination file name from selected file’s name”. It will force the GUI to consider the selected file to be the reference for automatically setting the file name, no matter which file was originally added as the first file. It will also force setting the destination file name once if automatic destination file name generation is turned off in the preferences. Implements part of #2058.
  • MKVToolNix GUI: multiplex tool: added an option in the preferences on “Multiplexer” → “Output” labeled “Only use the first source file that contains a video track”. If enabled, only source files containing video tracks will be used for setting the destination file name. Other files that are added are ignore. Implements the rest of #2058.
  • MKVToolNix GUI: header editor: added support for editing the video colour attributes. Implements the second half of #2038.
  • MKVToolNix GUI: header editor: added support for the “video projection” track header attributes. Part of the implementation of #2064.
  • MKVToolNix GUI: job queue: selected jobs can now be move up and down by pressing the Ctrl+Up and Ctrl+Down keys. Additionally, push buttons to move them up & down are shown if the corresponding option is enabled in the preferences. Implements #2060.
  • mkvmerge: added support for the “video projection” track header attributes. Part of the implementation of #2064.
  • mkvinfo: added support for the “video projection” track header attributes. Part of the implementation of #2064.
  • mkvpropedit: added support for editing the video colour attributes. Implements one half of #2038.
  • mkvpropedit: added support for the “video projection” track header attributes. Part of the implementation of #2064.

Bug fixes

  • all: selecting the program’s language (e.g. via the –ui-language command-line option or via the GUI’s preferences) did not work on Linux & Unix if the LANGUAGE environment variable was set and didn’t include the desired language. Fixes #2070.
  • MKVToolNix GUI: removed the keyboard shortcuts for switching between the different tools (e.g. Ctrl+Alt+1 for the multiplexer). They overlapped with basic functionality on keyboards that use an AltGr key, e.g. German ones, where AltGr+7 emits {. As AltGr+key is implemented as Ctrl+Alt+key under the hood, this means that AltGr+7 is really Ctrl+Alt+7 which the GUI now took to mean “switch to the job queue” instead of “insert {“. Fixes #2056.
  • MKVToolNix GUI: header editor: after saving the file the GUI wasn’t updating its internal file modification timestamp. That lead to the GUI wrongfully claiming that the file had been modified externally when the user wanted to save the file once more, requiring a reload of the file losing all modifications made since saving the first time.
  • mkvmerge: DTS handling: some source files provide timestamps for audio tracks only once every n audio frames. In such situations mkvmerge was buffering too much data resulting in a single gap in the timestamps of one frame duration after frame number n – 1 (the second audio timestamp read from the source file was used one output frame too early). Fixes #2071.
  • mkvinfo: fixed a null pointer dereference if an EbmlBinary element’s data pointer is a null pointer. Fixes #2072.

Build system changes

  • configure: added option –disable-update-check. If given, the code checking online for available updates will be disabled. The update check is enabled and included in the GUI by default.
  • libEBML v1.3.5 is now required.

Other changes

  • mkvmerge: the option –colour-matrix has been renamed to –colour-matrix-coefficients in order to match the specification more closely. The old option name will continue to be recognized as well.

Install MKVToolNix on Linux Ubuntu

Run the following commands in Terminal to install MKVToolNix Matroska tools for Linux Ubuntu:

sudo apt-get update
sudo sh -c 'echo "deb http://mkvtoolnix.download/ubuntu/$(lsb_release -sc)/ ./" >> /etc/apt/sources.list.d/bunkus.org.list'
wget -q -O - https://mkvtoolnix.download/gpg-pub-moritzbunkus.txt | sudo apt-key add -
sudo apt-get update
sudo apt-get install mkvtoolnix mkvtoolnix-gui

Please note that in the first line of command “sudo sh -c ‘echo “deb http://mkvtoolnix.download/ubuntu/$(lsb_release -sc)/ ./” >> /etc/apt/sources.list.d/bunkus.org.list’” replace $(lsb_release -sc) with the Ubuntu release name. For example, to install it on Ubuntu 16.10, use yakkety in the code and thus the line becomes “$ sudo sh -c ‘echo “deb http://www.bunkus.org/ubuntu/yakkety/ ./” >> /etc/apt/sources.list’”
