kdenlive shows

Missing MLT module: glaxnimate
required to load Lottie animations

on Nixos 22.11. It still works but it would be nice to have glaxnimate available.

@turion Is it possible to package glaxnimate and include it in kdenlive?

Just can up with this

{ lib
, stdenv
, fetchFromGitLab
, cmake
, zlib
, potrace
, ffmpeg
, libarchive
, python3
, full
, wrapQtAppsHook
  # Python3
}:

stdenv.mkDerivation rec {
  pname = "glaxnimate";
  version = "0.5.1";

  src = fetchFromGitLab {
    owner = "mattbas";
    repo = "${pname}";
    rev = "${version}";
    sha256 = "G4ykcOvXXnVIQZUYpRIrALtDSsGqxMvDtcmobjjtlKw=";
    fetchSubmodules = true;
  };

  nativeBuildInputs = [
    cmake
    wrapQtAppsHook
  ];
  
  buildInputs = [
    zlib
    potrace
    ffmpeg
    # gst_all_1.gst-libav # Note that since gst-libav-1.6, libav is actually ffmpeg
    libarchive
    python3
    full    
  ];

  meta = with lib; {
    homepage = "https://gitlab.com/mattbas/glaxnimate";
    description = "Simple vector animation program.";
    license = licenses.gpl3;
    maintainers = with maintainers; [ tobiasBora ];
    platforms = platforms.linux;
  };
}

it works but when I integrate it in nixpkgs I get an error about

Package ‘qtwebkit-5.212.0-alpha4’ in /home/leo/nixpkgs/pkgs/development/libraries/qt-5/qtModule.nix:72 is marked as insecure, refusing to evaluate.

so I need to investigate

Thank you for your effort!

You can override that with nixpkgs.config.permittedInsecurePackages = [ "qtwebkit-5.212.0-alpha4" ];.

Unfortunately, this package is compiled locally and takes quite a while. I don't know why it's not built by hydra.

[turion]

👍 for adding glaxnimate. It looks like a sane program that can be packaged without headaches.

It's weird that qtwebkit is pulled in here. qtwebkit is insecure afaik and shouldn't be used anymore. See #53079. And it seems to me that glaxnimate doesn't need qtwebkit, so it's added as a transitive dependency somehow.

[tobiasBora]

Qtwebkis just go added because I used qtfull instead of manually adding the libraries one by one.

But please test the program in #209669 as I don't know how to test it beside runnig it. In particular the python stuff might need some wrapping but no idea/time how to test it.

Can you give more details on how to reproduce? I can't see this error. Do I have to do anything special to trigger it?

[turion]

(Ideally, as a separate issue.)

[hervyqa]

hi @turion. how do i know if this pkgs status goes into repo 22.11?

[turion]

You can use git for example. There is also a webservice: https://nixpk.gs/pr-tracker.html You have to enter the number of the PR there.

@turion It happened when launching kdenlive for the first time i.e. without config files in my home directory. Then it apparently registered that i acknowledged the message and didn't show it again. It was a message window that had to be acknowledged with "ok" or something like that. No fatal error, just an information.

I think that kdenlive is working correctly in this regard and that i shouldn't file an issue about that.

[tobiasBora]

Oh very true… I just tried by doing

$ mkdir /tmp/home
$ export HOME=/tmp/home
$ nix run github:NixOs/nixpkgs/0c9aadc8eff6daaa5149d2df9e6c49baaf44161c#kdenlive

I created an issue here #209923
