I am proud to be able to announce, that per today, I have been able to complete the long cycle of creating a new set of kdenlive packages for the Slackware community.
I have split up all dependencies for ffmpeg into a separate package, so that upgrading each part should become much easier. For each of those packages I have tried to install the most recent version, so with these you're pretty much in shape for an upcoming upgrade of kdenlive.
For those that have installed kdenlive, ffmpeg etc from my previous packages: please uninstall those prior to installing these new packages. I am sorry I cannot make this any easier than that, but I bet that this is a small step, even if it may not be so small for mankind ;-)
Please be aware that it will be very hard for me to provide support on packages I did not create, however: each package contains the slackbuild script used to create the package in /usr/doc/
Please use this forum to provide feedback and upgrade requests, and I'll do what I can to meet your request.
This overhaul has cost me quite some time and effort, however, I am very pleased with the result so far.
