ffmpeg is not running in Ubuntu 22.04 LTS.

$ ffmpeg -version
ffmpeg: error while loading shared libraries: libaom.so.0: cannot open shared object file: No such file or directory

Ubuntu version

$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 22.04.1 LTS
Release:        22.04
Codename:       jammy

System information:

$ uname -a
Linux r2d2 5.15.0-48-generic #54-Ubuntu SMP Fri Aug 26 13:26:29 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux

I've tried to reinstall ffmpeg and its dependencies and the error is still the same.

$ apt-cache depends ffmpeg | grep '[ |]Depends: [^<]' | cut -d: -f2  | tr -d ' ' | xargs sudo apt-get --reinstall install -y
$ sudo apt reinstall ffmpeg

Any tips on how to solve it?

Find a file in `/usr/lib/x86_64-linux-gnu` that starts with `libaom.so`. There is probably only one. It could be e.g. `libaom.so.3.3.0`. Then create a symbolic link: `sudo ln -s /usr/lib/x86_64-linux-gnu/libaom.so[...full filename] /usr/lib/x86_64-linux-gnu/libaom.so.0`. Now the file `libaom.so.0` can be found by `ffmpeg`.

@Jos after doing that a similar problem happened for ```libfdk-aac.so```, ```libx264.so``` and ```libx265.so```. I installed the packages ```libfdk-aac-dev```, ```libx264-dev``` and ```libx265-dev``` and created links as you proposed. Now the error is: ```ffmpeg: symbol lookup error: ffmpeg: undefined symbol: x264_encoder_open_160```

At this point, you may as well reinstall `ffmpeg`: `sudo apt install --reinstall ffmpeg`.

@Jos, I've done that... still the same error.

```$ whereis ffmpeg``` ```ffmpeg: /usr/bin/ffmpeg /usr/share/ffmpeg /home/leoca/bin/ffmpeg /usr/share/man/man1/ffmpeg.1.gz ``` oh... I don't know why... but there is one in my home folder... removing it solves the issue

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
