Hello everyone, I’ve been experiencing some problems with ffmpeg, with both packages from the `updates` and `rpmfusion-free` repos, yielding the same error: `ffmpeg: error while loading shared libraries: libjack.so.0: cannot open shared object file: No such file or directory`, sometimes the same error with other libraries. [Another ffmpeg user](https://www.reddit.com/r/Fedora/comments/1ftafh0/comment/lqswv60/?context=3) has been experiencing the same problems and temporarily solved the problem by uninstalling everything while in root, but I figured it would be a good idea to address it here as well. ---

Sorry, I just mentioned the other user’s error as an example, my error was about `libavdevice.so.60`, which is provided by `libavdevice`, which I already have installed, but still outputs the same error. There were a few more libraries mentioned, like (I believe) `libglut`, but nevertheless, ffmpeg used to work as intended until recently. ---

You should provide the steps to reproduce the issue and the installed package version. It seems to work for me, so it currently looks like a problem with your setup. ---

Yes, it might be a problem with my setup, because I tried typing `ffmpeg` on another computer running a super minimal Fedora 40 install and it launched successfully. This problem (probably) begun when I tried installing `ffmpeg` from the RPM Fusion Free repo, meaning that I first had to remove the `ffmpeg-free` package that comes with Fedora 40. After doing so, I get the error posted above upon typing `ffmpeg`in the Terminal, with the error mentioning `libavdevice.so.60` instead. After removing RPM Fusion’s ffmpeg, all its dependencies and doing a `sudo dnf autoremove`, I disabled the repo and reinstalled `ffmpeg-free` and this time getting the following error: `ffmpeg: error while loading shared libraries: libglut.so.3: cannot open shared object file: No such file or directory` ---

Check the output: ```bash rpm -q freeglut; rpm -V freeglut ``` ---

It get: `package freeglut is not installed` ---

```bash sudo dnf install freeglut ``` Then check ffmpeg again. ---

It’s running now, thank you! A few things I don’t understand: 1. shouldn’t these dependencies be part of ffmpeg-free? 2. how would I know what library contains libglut.so.3? (I’m guessing doing `sudo dnf whatprovides libglut.so.3`?) 3. in case of the Reddit user’s problem posted above, he was missing multiple dependencies. It could have been due to malconfiguration on my part by uninstalling and reinstalling a lot of things prior to the problem, but the Reddit user seems to have just gotten this error as is. ---

Yes, it should be: ```bash > ldd $(type -P ffmpeg) | grep -e libglut libglut.so.3 => /lib64/libglut.so.3 (0x00007efcc8d2c000) ``` > [@dsnvs](#): > > how would I know what library contains libglut.so.3? ```bash dnf provides \*/libglut.so.3 ``` See also: [DNF Command Reference — DNF @DNF\_VERSION@-1 documentation](https://dnf.readthedocs.io/en/latest/command_ref.html#provides-command-label)
