Ffmpeg: error while loading shared libraries: libSvtAv1Enc.so.0

Support Software & Applications
1

Hi guys,

when running ffmpeg I’m getting the following error:

ffmpeg: error while loading shared libraries: libSvtAv1Enc.so.0: cannot open shared object file: No such file or directory

Apparently the reason for this is usually a custom ffmpeg-build (e.g. installed via AUR) and can be fixed by rebuilding ffmpeg. However, my ffmpeg is installed from the official repos.

>> pacman -Qo /usr/lib/libSvtAv1Enc.so* 

/usr/lib/libSvtAv1Enc.so ist in svt-av1 1.1.0-1 enthalten
/usr/lib/libSvtAv1Enc.so.1 ist in svt-av1 1.1.0-1 enthalten
/usr/lib/libSvtAv1Enc.so.1.1.0 ist in svt-av1 1.1.0-1 enthalten

>> pacman -Qi ffmpeg svt-av1

Does anyone know how to fix this? Should I just link /usr/lib/libSvtAv1Enc.so to /usr/lib/libSvtAv1Enc.so.0?

2

Reinstall svt-av1 package and reboot:
pamac install svt-av1

3

I have already tried that (reinstalling ffmpeg too), it doesn’t work.

4

The packages looking up to date. Are you sure you using the ffmpeg binary from the repo package?

What is the output of

which ffmpeg

and can you try start ffmpeg with the full path?

/usr/bin/ffmpeg

Ahhh, it was also installed via anaconda and accessing this instead. For whatever reason removing ffmpeg and svt-av1 didn’t remove the according files in ~/anaconda3/bin, so I had to delete them manually. Now it works, thanks!

The package manager doesn’t remove files that are not part of the package. It will only install and remove files that are included in the specific packages. And of course a system package manager does not touch your Home directory. Files you create in your Home will not remove, no matter what, even if it’s a binary that provides the same function and has the same name.

I mean removing the packages via conda (after removing the pacman-packages) didn’t remove those files.

EDIT: I guess it shouldn’t be like this, but removing conda-ffmpeg with sudo worked now.
