How to install ffmpeg 4.4.2 or higher on Ubuntu 20.04 server

[Bo Berglund]

I have run into a problem with ffmpeg on my Ubuntu 20.04 LTS server...

The server is used for many things like Subversion server, OpenVPN server, Video
file server and more.

Now I found an error in one of the video downloaders used on this server which
is apparently resolved in ffmpeg 4.4 and above.

On this server I have:

apt policy ffmpeg
ffmpeg:
  Installed: 7:4.3.2-0york0~18.04
  Candidate: 7:4.3.2-0york0~18.04

On another server which was upgraded to 22.04 a few months back I see:

$ apt policy ffmpeg
ffmpeg:
  Installed: (none)
  Candidate: 7:4.4.2-0ubuntu0.22.04.1+esm3

So the 4.4.2 version is on Ubuntu 22 and 4.3.2 on Ubuntu 20...

How can I force the installation of the newer version of ffmpeg on my server
20.04?

I cannot upgrade the server to 22.04 since it is mission-critical..
