Many individuals love MKV due to the way it can compress giant quantities of uncooked audio and video footage right into a small package deal. One other nice characteristic of MKV is how straightforward it’s to change the contents of it. The most effective instruments on Linux that may extract data from MKVs is MKVToolNix.
Set up MKVToolNix
Putting in the MKVToolNix apps offers customers an excellent set of GUI and command-line applications to simply modify, examine and tinker with MKVs. Select your working system under and observe the instructions to get the software program working.
Ubuntu
As of now, the MKVToolNix utility set helps Ubuntu 16.04, 17.10 and 18.04. To get it working, you’ll have to edit the Ubuntu software program sources file manually. The explanation you’ll have to edit this file is that the developer of MKVToolNix doesn’t at the moment have a customized PPA out there. Nonetheless, including software program repositories on this manner is hardly that totally different.
To add the brand new software program supply, open up a terminal window and use the Nano textual content editor to edit the /and so on/apt/sources.listing file in your Ubuntu PC.
sudo nano /and so on/apt/sources.listing
Within the sources file, press the down arrow key on the keyboard to maneuver all the best way to the underside of the file. As soon as there, add a brand new remark. Don’t skip the remark half! When you fail so as to add a remark, you could overlook what this software program repository does at a later time.
# MKVToolNix Ubuntu repo
After including the remark, it’s time so as to add the software program supply. Select your model of Ubuntu, and paste the code in Nano.
Ubuntu 16.04
deb xenial predominant
deb-src xenial predominant
Ubuntu 17.10
deb clever predominant
deb-src clever predominant
Ubuntu 18.04deb bionic predominant
deb-src bionic predominant
Now that the brand new software program supply is added to Ubuntu, you’ll want so as to add the signed GPG key as properly, in order that Ubuntu will enable the software program from this new repository to put in in your system. When you skip this step, MKVToolNix won’t work.
wget -q -O - | sudo apt-key add -
Lastly, after the modifications are full, it’s time to refresh Ubuntu, set up some upgrades and get MKVToolNix working.
sudo apt replace sudo apt improve -y sudo apt set up mkvtoolnix mkvtoolnix-gui
Observe: if the apt replace command fails to put in, you’ll want first to do that:
sudo apt set up apt-transport-https
After apt-transport-https is working, strive putting in MKVToolNix once more.
Debian
Putting in the MKVToolNix set of functions on Debian is similar to Ubuntu, because the developer has chosen to distribute the software program through repositories. To get the app engaged on Debian, open up a terminal and use the Nano textual content editor to edit the /and so on/apt/sources.listing file.
Observe: MKVToolNix formally helps Debian 9 Secure and Debian 8.
sudo nano /and so on/apt/sources.listing
Contained in the sources file, use the arrow keys and transfer all the best way to the underside of the file. Press # so as to add a brand new remark line.
# MKVToolNix Debian Repo
Now that the remark line is within the sources file, it’s protected so as to add the software program repository URLs instrument.
Debian 9
deb stretch predominant
deb-src stretch predominant
Debian 8
deb jessie predominant
deb-src jessie predominant
After including the brand new software program supply, use the wget command so as to add the GPG key.
wget -q -O - | sudo apt-key add -
Use the replace and improve instructions to refresh and set up updates on Debian.
sudo apt-get replace sudo apt-get improve -y
Lastly, set up the MKVToolNix apps:
sudo apt-get set up mkvtoolnix mkvtoolnix-gui
Arch Linux
The entire MKVToolNix functions are available in the primary Arch Linux software program sources. To set up them, open up a terminal and use the Pacman, package deal supervisor.
pacman -S mkvtoolnix-cli mkvtoolnix-gui
Fedora
MKVToolNix helps Fedora from variations 26 to twenty-eight (the present launch). To set up the software program, you’ll want so as to add the official software program repository. Utilizing dnf, seize this RPM file and set up it.
sudo dnf set up -y
With the brand new MKVToolNix repo lively on Fedora, use dnf to put in this system.
sudo dnf set up mkvtoolnix
OpenSUSE
OpenSUSE has MKVToolNix out there through a third-party software program repository. To add the repo, open up a terminal and execute the next instructions.
Observe: MKVToolNix, as of now, solely helps OpenSUSE 42.3 Leap.
wget sudo rpmkeys --import gpg-pub-bunkusorg-rpm-signing.txt sudo zypper addrepo --refresh MKVToolNix
When all the pieces is enabled, set up the software program utilizing Zypper.
sudo zypper set up mkvtoolnix
Utilizing MKVToolNix
MKVToolNix could be very helpful and is fast to import or export knowledge to an MKV container. When you’re trying to acquire audio, video or subtitles (SRT) from inside an MKV, right here’s what to do. First, open up the GUI app, by trying to find “MKVToolNix” in your utility menu.
As soon as open, click on on “multiplexer.” Within the multiplexer window, search for the “Add source files” button and click on on it. Utilizing the file browser, find and add an MKV file to this system.

Find the default audio observe and make sure that the field subsequent to it’s checked.
Click on the “start multiplexing button” to begin the extraction. The audio file might be proper subsequent to the MKV file you’ve imported.
Extract Video
Extracting video from MKV information works the identical manner because the directions for exporting audio. Begin off by including a brand new MKV file. Subsequent, uncheck the bins subsequent to the audio observe and subtitle observe.
Verify the field subsequent to the default video observe. When all the pieces appears to be like good, click on the “start multiplexing” button. Quickly after, the uncooked video observe will extract to the identical folder that the supply MKV video file is in in your PC.
