Good morning, I had install ffmpeg by web site: https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu. I removed all install problems. But i had problem when launch ffmpeg command "ffmpeg: error while loading shared libraries: libfdk-aac.so.1: cannot open shared object file: No such file or directory". I had look at in web and i found the problem is the "libfdk-aac0" library is not present. This library (was present on ubuntu 20.04 and I installed it) is not present on ubuntu 22.04. What i have to do?

Thanks

  • Seems odd, perhaps reinstall the library: sudo apt-get install libfdk-aac-dev and try ffmpeg again...

  • It's not available for Ubuntu 22.04 yet - If it's not available anywhere, then I guess that the only solution is to build it from sources, and install.

the package has not been released on 22.* apt repository, but you can find the debian package here: https://packages.debian.org/sid/amd64/libfdk-aac2/download. Be sure to download the right architecture one.

    thanks, I test it. If I didn't get your answer I would have tried the ubuntu version 20.04 library. But I don't know if it would have worked.

  • Probably it would work as well, consider that my link points to debian, I think that ubuntu 20.04 is closer to version 22. Anyway if you face any problem, you can build from sources. Ciao!

This seems to be available directly in apt now (running Kubuntu 22.04), so you don't need to download the debfile separately. However, for me (at least) the issue remained. I had to manually softlink the library which fixed problems with VLC and ffmpegthumbnailer.

I have the package installed:

sudo apt install libfdk-aac-dev
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
libfdk-aac-dev is already the newest version (2.0.2-1).

and the libraries exist:

ls /usr/lib/x86_64-linux-gnu/libfdk-aac.
libfdk-aac.a
libfdk-aac.so        
libfdk-aac.so.2      
libfdk-aac.so.2.0.2

Installing the debfile manually doesn't create this file either. I've tried making a soft link:

sudo ln -s /usr/lib/x86_64-linux-gnu/libfdk-aac.so /usr/lib/x86_64-linux-gnu/libfdk-aac.so.1

Though this might not work all the time, because in theory so.1 and so.2 are not ABI compatible (as I understand the naming schemes). But why would these tools (also installed on apt) depend on an outdated library. So it's possible something else went wrong during the upgrade.
