I have an avidemux package in my (restricted) repository.
But… it had not been refreshed since Slackware 14.0 (8 years old now) and its binaries stopped working on Slackware long ago. Looking back at the packaging work I did today, I guess the thing that kept me from updating that Avidemux package was the numerous dependencies that also needed an update (they all were stuck at an old Slackware 14.0 release).
In the midst of a full week of holidays and waiting for my rye/honey sourdough bread dough to ferment, I had plenty time to devote to the creation of a fresh package for Avidemux 2.8.0. This was recently released; yesterday actually!
And not just avidemux needed some work on its SlackBuild script; I needed to update ageing scripts for aften, faac, faad2, libdca, libfdk-aac, opencore-amr, x264 and xvidcore, and added a x265 package before I could compile avidemux with full support for codecs and plugins.
Based on the imminent (fingers crossed) release of Slackware 15.0 according to Patrick himself, I decided to create these packages only for Slackware-current (soon to become 15.0). I also cleaned out ancient versions of all these packages. They are now removed for Slackware 14.1 and older.
Note that faac and libfdk-aac just like avidemux contain patent-encumbered software (the AAC encoder) and due to that circumstance the three packages are banished to my ‘restricted repository‘ which is hosted outside the US of A so that the patent trolls won’t bother Pat.
Let me cue you in about Avidemux in case you are not familiar with the program.
It’s a video editor supporting many video formats thanks to the built-in ffmpeg libraries and many plugins. It allows for a decent level of automation through tasks and scripts, and it has a command-line interface next to its Qt5-based graphical user interface.
Some of the 2.8.0 release highlights: Avidemux is now able to convert HDR video to SDR with tone mapping using a variety of methods. The FFV1 encoder has been added again. TrueHD audio tracks can be decoded and are supported for Matroska containers. The internal ffmpeg libraries are the latest 4.4.1 version. It integrates better with pulseaudio in terms of volume adjustments.
In case you are interested in some comparisons between the functionality of Avidemux and its competitors, here are some pointers. In terms of video conversion capability it compares to Handbrake (also in my repository), see here: https://en.wikipedia.org/wiki/Comparison_of_video_converters. When you look at its video cutting and edting qualities on the other hand, Avidemux is better compared with Kdenlive which is included in Slackware as part of KDE Plasma5: https://en.wikipedia.org/wiki/Comparison_of_video_editing_software
FYI… my sourdough bread is out of the oven, and it’s smelling great!
