how to solve?

Are you within a virtual environment (with guaranteed package versions installed)? Or are you trying to build it natively? It looks like the version mismatch of libffi.

I am uanble to compile the library in Ubuntu 24.04, it says Package 'g++-8' has no installation candidate.
Is there a quick fix to this apart from running it in docker?

g++-8

Assuming you are following the Wiki from "https://github.com/TadasBaltrusaitis/OpenFace/wiki/Unix-Installation#dependency-installation"...
You could try to use newer versions of those packages which can't be installed on something new like Ubuntu 24.04. However, there will be many libraries in the meantime... OpenFace has many, many dependencies.

The MASTER branch is quite old and doesn't seem to still be maintained...

You might want to have a look into alternatives, like under "https://github.com/cmusatyalab/openface"

Basically I am trying to run this specific code for a research project. The main goal is to extract key frame from a video based on maximum intensity of action units. can you suggest some alternate to openface library.

[brmarkus]

No, can't suggest alternatives.
However, it runs great in a Docker container environment.

[staru09]

Yes I tried running it with docker, it worked fine. Will use that only.

Thanks for this amazing library though.

[brmarkus]

Don't thank me, I'm a user, too.
