Avidemux startup error, missing library (libADM_coreVideoCodec6.so)

[revuwa]

Describe the bug

avidemux could not be started since a few days/weeks. (Worked well before).

Steps To Reproduce

Steps to reproduce the behavior:

1. nix-shell -p avidemux
2. avidemux
3. message: avidemux: error while loading shared libraries: libADM_coreVideoCodec6.so: cannot open shared object file: No such file or directory

Expected behavior

The application starts without any problems, as it does some days (and nixos-rebuild switch --upgrade) cycles before.

Additional context

I sadly have no idea, since when the error occurs exactly, and why. Because the package itself wasn't touched for a while:
https://github.com/NixOS/nixpkgs/commits/nixos-unstable/pkgs/applications/video/avidemux/default.nix
and it definitely worked with this last commit. So something other have to be changed, or it is just on my side. Hopefully someone could verify it the 'steps to reproduce' works for other people?

I searched for the missing library in the path where it seems to be missed:
"/nix/store/4m7z30fmc4pkivr55ww84sjpqxy4gppi-avidemux-2.8.1/bin/avidemux: error while loading shared libraries: libADM_coreVideoCodec6.so: cannot open shared object file: No such file or directory"
and found it two times:

• /nix/store/4m7z30fmc4pkivr55ww84sjpqxy4gppi-avidemux-2.8.1/lib/libADM_coreVideoEncoder6.so (symlinked from lib64)
• /nix/store/4m7z30fmc4pkivr55ww84sjpqxy4gppi-avidemux-2.8.1/lib64/libADM_coreVideoCodec6.so

Tried:
sudo nix store repair /nix/store/4m7z30fmc4pkivr55ww84sjpqxy4gppi-avidemux-2.8.1
to enforce rebuild the package, and after that by override an attribute inside my configuration.nix, which let avidemux recompile completely. With the same result/error.

Grateful for any hint.

I used git bisect to identify #223861 as the possible breaking change, and as you noticed avidemux seems to be expecting the missing library in its lib64 directory.

I'm not sure how to fix the derivation, but setting LD_LIBRARY_PATH to /nix/store/4m7z30fmc4pkivr55ww84sjpqxy4gppi-avidemux-2.8.1/lib/ should work. For example: LD_LIBRARY_PATH=$(dirname $(readlink -f $(which avidemux)))/../lib/ avidemux

Thanks for looking into this. 💕
In my case which avidemux points to /run/current-system/sw/, and under its lib folder, the missing lib doesn't exists.

I tried setting the environment variable over my configuration.nix like this:

environment.variables = {
LD_LIBRARY_PATH = "${lib.getLib pkgs.avidemux}/lib";
};

Whith this result:

$ set | grep LD_LIBRARY_PATH
LD_LIBRARY_PATH /nix/store/jdzg2ghp71gg07yn3cvwdp66fgc5z8pd-avidemux-2.8.1/lib

(Also tried: [...]-avidemux-2.8.1/lib/).

But still with the same result:
/nix/store/jdzg2ghp71gg07yn3cvwdp66fgc5z8pd-avidemux-2.8.1/bin/avidemux: error while loading shared libraries: libADM_coreVideoCodec6.so: cannot open shared object file: No such file or directory

Thanks again, it sounded promising. 🚀

Short summary, because in the meanwhile I know that other people have the same issue with unstable:
$ nix run nixpkgs#avidemux
/nix/store/jdzg2ghp71gg07yn3cvwdp66fgc5z8pd-avidemux-2.8.1/bin/avidemux: error while loading shared libraries: libADM_coreVideoCodec6.so: cannot open shared object file: No such file or directory

But stable (23.05) works like a charm:
$ nix run nixpkgs/nixos-23.05#avidemux

If someone is searching for a workaround...

@mgurlitz I can confirm that env LD_LIBRARY_PATH=$(dirname $(readlink -f $(which avidemux)))/../lib/ avidemux does work.

I tried messing with patchelf and makeWrapper to fix the issue but wasn't able to. When I run strace on the broken avidemux, it looks for these .so files in many directories, but I was only able to control this search using LD_LIBRARY_PATH.

If you want to embed that workaround in an overlay for now, I ended up using this:

final: prev:
{
  avidemux = prev.avidemux.overrideAttrs (oldAttrs: {
    buildCommand = oldAttrs.buildCommand + ''
      mv $out/bin/avidemux $out/bin/avidemux3
      echo 'LD_LIBRARY_PATH=$(dirname $(readlink -f $(which avidemux3)))/../lib/ avidemux3 "$@"' >> $out/bin/avidemux
      chmod +x $out/bin/avidemux

      mv $out/bin/avidemux3_cli $out/bin/avidemux3_cli_old
      echo 'LD_LIBRARY_PATH=$(dirname $(readlink -f $(which avidemux3_cli)))/../lib/ avidemux3_cli_old "$@"' >> $out/bin/avidemux3_cli
      chmod +x $out/bin/avidemux3_cli
      '';
  });
}```

I'm so sorry for my #239424 (comment) whilte this seems to work, but I forgot that I've wrapped avidemux with firejail. 🙄

So the workarounds from #239424 (comment) and #239424 (comment) working for me, too (without firejail wrap).

For those who're interested in the firejail-wrap, the following works for me:

firejail = {
  enable = true;
  wrappedBinaries = {
    "avidemux" = {
      executable = "${lib.getBin pkgs.avidemux}/bin/avidemux";
      extraArgs = [ "--env=QT_QPA_PLATFORM=xcb" "--env=LD_LIBRARY_PATH=${lib.getLib pkgs.avidemux}/lib"]
    };
  };
};

Very big thanks to all of you 🥰
