New handbrake and mkvtoolnix packages for Slackware 14.2 and -current

handbrake_logoI was a couple of releases behind on the Handbrake video transcoding software. I am always a bit hesitant with upgrading Handbrake. It has a history of being hard to compile on the stable Slackware releases.

Most notably it is the GTK+3 based GUI for which our Slackware libraries are often too old. And indeed, with the latest 1.3.0 release I found that this would not compile on Slackware 14.2 despite the hack I already used for the previous package (1.2..2) which I created earlier in 2019. It took me a day to come up with a second patch that allows Handbrake 1.3.0 to compile against our gtk+3 3.18.9 while in fact the program’s GUI component wants gtk+3 3.20.0 or higher.
So, Slackware 14.2 users – please tell me if you find that some functionality of the GUI is not working… it should all work properly but you never know.
In addition, I had to add a patch to make the new dav1d AV1 decoder compile on Slackware 14.2 but luckily I could just re-implement what I had already done for VLC.

The package for Slackware-current built without any glitches. Yay.

Note that my ‘handbrake‘ package does not have any external dependencies – unlike the slackbuilds.org version.
Install and run, it’s that simple. Everything you need is compiled statically into the package. TheĀ ‘HandBrakeCLI‘ program is the command-line variant, whereas ‘ghb‘ is the GUI variant of HandBrake, also found in the “Multimedia” menu of your desktop environment.

Packages for Slackware 14.2 and -current with AAC audio encoding support can be obtained from my “restricted” repository:

The variant which does not support AAC audio encoding and therefore does not violate the stupid US software patents can be downloaded from the regular repository:


I also have neglected my mkvtoolnix package for a while. You may be aware already that MKVToolNix is a set of tools to create, alter and inspect Matroska files (most widely known as the MKV video container format).

When working on the handbrake packages, I decided to check out the latest mkvtoolnix as well. And what do you know… the latest release won’t compile on Slackware 14.2!
I went back through the releases of 2019 and found that 38.0.0 is the most recent version which still compiles using the gcc compiler of Slackware 14.2 against the boost libraries of Slackware 14.2. Anything newer will not compile. End of the line for mkvtoolnix releases on the stable Slackware then.
These issues are absent on Slackware-current. I could compile mkvtoolnix 41.0.0 (the most recent release) easily.

Note the dependencies for mkvtoolnix:
Since its GUI and multimedia support is based on Qt5, you’ll have to install libxkbcommon and qt5 from my repository. And the qt5 dependencies as well: OpenAL and SDL_sound. On Slackware 14.2 two more even: libinput and libwacom.
Starting with mkvtoolnix 20.0.0 there’s another, new, dependency: cmark. Like with all the other dependencies I mentioned, cmark can be downloaded from my repository or any of its mirrors.
