Hello, all.

In the ongoing effort to finally rid my computer of the vile heinousness that is PulseAudio, I just recompiled my KDEnlive without pulse support. The program launches and seems to be operating as normal, but when I open any project, or try to add clips to a new project, it gives me an error saying "Clip is invalid and will be removed from project" and removes literally every clip from the project. Well, it saves the color clips that were created inside KDEnlive, but every clip, sound or video, that was imported from an external source gets removed.

Now, KDEnlive used to work just fine before I removed pulseaudio. Then, it would complain about the missing libraries. So, I went about re-compiling it. The compile crashed when it tried to link against libphonon which was still looking for some pulse library. So, I recompiled libphonon. That seemed to work perfectly. And then when I recompiled KDEnlive, it seemed to go perfectly well too.

So, what's wrong? Working with a locally compiled binary of a program that used to work just fine. Any ideas?

Thank you!

Okay, I went ahead and reinstalled the version that came with the distribution. When I tried to launch it it acted like it was newly upgraded (even though it was an older version) and in the little setup wizard it showed a red X next to Avformat. I checked and I have two versions of libavformat in /usr/lib64

Why would it no longer be seeing libavformat? I did an ldd on both libavformats and neither one showed any missing dependencies.

Okay, it turns out that KDEnlive is heavily dependent on MLT, and in my computer's case it's MLT-6. I learned from a post on some other site to do an ldd on libmltavformat.so, which showed me that it was still looking for a pulseaudio library, all of which have been eradicated from my computer.

My initial response to that, of course, was to recompile MLT-6. That crashed with a nasty-looking error that felt like it would be way too much effort to correct, so I just went ahead and tried launching KDEnlive with apulse

and that worked. It's now using the recompiled binary that I created earlier, and it works just like it did before.

So, the moral of the story is, if you want to get KDEnlive to see libavformat, check your MLT installation. If you want to get KDEnlive running without PulseAudio on your machine, and you can't get MLT to compile, try apulse. It seems to work.
