The ffmpeg version in the ppa is 7:7.1-1build2~jammy
Which is ffmpeg 7.1, your version is the default Ubuntu version for 
22.04 that is fairly obsolete and unsupported by ffmpeg (the lts version 
is 4.4.5)
The +esm5 means it is an Expanded Security Maintenance release (the 
fifth one) most likely cherrypicking only security updates from 4.4.5 
(but not feature updates)

The following commands in a terminal should add the ppa to your system

sudo add-apt-repository ppa:ubuntuhandbook1/ffmpeg7
sudo apt update

Your existing ffmpeg version should then be upgraded by the version in 
the ppa when you do sudo apt upgrade
