Custom build has effects missing (and named strangely)

[Johannes Bauer]

Hi list,

I'm trying to get a custom kdenlive build to work. After
build-kdenlive.sh wouldn't work for me anymore
(https://forum.kde.org/viewtopic.php?f=269&t=151446) I decided to build
my own kdenlive build script (https://github.com/johndoe31415/mkkdenlive).

With it, I'm able to successfully create a kdenlive build (and all
dependencies that build-kdenlive.sh also builds). However, while the
final version works, the effects are somehow messed up:

- When I right-click a video snippet that I pulled in the timeline, the
"Effects" submenu is empty.
- When I load an old kdenlive file in which I've used the pan/zoom
effect, kdenlive complains upon loading: "Effect affine:pan_zoom not
found in MLT, it was removed from this project" -- in fact it complains
about a lot of other missing filters as well (see [1]).
- The names of the effects in the effect stack seem to be "raw"
identifiers (e.g., "Zoompan" instead of "Zoom and Pan" or similar).
- When I try to apply "Zoompan" to a clip, it doesn't have any settings
that I could modify.

I'm pretty certain that I'm almost able to create a fully working build,
but haven't been able to figure out why this happens. Any help would be
greatly appreciated.

Thank you very much,
Johannes
