Ubuntu doesn't play videos and some audio media formats after fresh install for example is a common issue. The lack of this support is due the video files and other media formats are restricted by patent, copyright, or legal issues.
The good thing is, Canonical provides a single package to install all the essential media codecs from their repository to provide non-open source software to its users. You can use this on any Ubuntu e.g 20.04 LTS, 20.10, 22.04 LTS, 22.10.
WHAT IS UBUNTU RESTRICTED EXTRAS?
Ubuntu-restricted-extras is a software package that consists various essential software like MP3 and other audio codec software to play various audio formats, Microsoft web fonts, unrar, mp4, and codecs for Chromium browser, etc.
UBUNTU WON'T PLAY DVD MOVIES
The same problem occurs when you want to play a DVD even after you installed all the codecs. Here are all you have to do to get DVD Playback (follow on-screen instructions and reboot your computer to apply the changes) :
sudo apt install libdvd-pkg
sudo dpkg-reconfigure libdvd-pkg
FIX LIBDVDREAD4 NOT AVAILABLE
If you're facing "libdvdread4 not available" error (I think this only happens on Ubuntu 20.04 LTS Focal Fossa and higher), libdvdread package available as libdvdread7. So run this command to install it :
sudo apt install libdvdread7
