I'm having one issue with Kdenlive on Slackware 14.2, and I can't seem to figure it out. Maybe I've had too much coffee : ) This is a stock 14.2, no Plasma 5.

I have FFmpeg 3.1.3 installed with all it's Deps, plus I have LibDV installed.

Kdenlive runs but says it requires:

AVFormat Module (FFMPEG)

DV Module (LibDV)

Any ideas?

Thanks,

How did you install this software? If it is from pre-compiled packages, it could very well be that kdenlive expects one version of ffmepg and libdv, but you have different versions installed.

If you did use pre-compiled packages, it is recommended to at least compile kdenlive rather than use a pre-built package, as then it is able to use the versions that are installed on your computer.

Can you do the following and provide the output?

Well, none of the package management tools see the ffmpeg install, so I can't use them uninstall it. I compiled it and installed it, but it is not logged anywhere : (Thank goodness for make uninstall) So, ffmpeg is probably causing an issue with AVFormat : )

ls: cannot access '/var/log/packages/ffmpeg-*': No such file or directory

I tried the SBo ffmpeg package at SlackBuilds, but it won't install. So I will compile the latest ffmpeg (3.1.3) - and LibDV and then compile Kdenlive - we'll see what happens then : )

That's correct, if you don't use makepkg to create your package and then install it, the system can't know what was done. However, I'm not positive that ffmpeg installed into /usr/local/ would prevent kdenlive to pick it up. Even more confusing, both ffmpeg and libdv aren't mentioned as direct dependencies on the kdenlive page on SBo. Looking into the dependencies on there, ffmpeg and libdv are both dependencies of other programs that are dependencies of kdenlive. This could mean that things weren't built in the proper order to allow kdenlive to pick everything up.

This is when a program like sbopkg with its sqg utility come in handy. It will generate a build queue for everything to help you install stuff in order. The only exception to that is ffmpeg, due to its massive amounts of optional dependencies. I would recommend building that one after building all the dependencies you want (making sure you pass the required variables if needed), then proceed with building the rest of the dependencies for kdenlive.

Why wouldn't it install? I'm using ffmpeg from SBo on my computer.

Dude, have some patience and compile everything neatly from SlackBuilds.org. I have ffmpeg, vlc, kdenlive, and audacity, all from SlackBuilds and all running very well. It took me some time to compile them but it is totally worth it. Everything works seamlessly and the system is very stable. Haven't seen a crash or error.

Well, I tried using all SBO packages, and Kdenlive still gives me the same message when running the Config Wizard, it claims that the AVFormat module (ffmpeg) & DV Module (libdv) are not installed....and they are indeed installed.

All the deps for each program & deps are from Slackbuilds.org - I did that for consistency purposes, but I get the same error.

So, my next plan is to go and fetch all the programs & deps, get the LATEST versions of each, compile them and then see what comes of my mess : )

Thanks by the way for all your input, I'm not frustrated, I'm learning : )

Can you run it from the commandline, especially if it has a verbose option? I'm not sure if libdv and ffmpeg are build dependencies or just run dependencies. You'd probably have to check out the ./configure output to see if it detected them.

Interesting, it crashes when I use the command line:

Nice to see someone eager to learn. What you will be trying is highly experimental. If you have any problem, give details about what you tried and paste the errors output from the command line into your post.

All the best.
