Can not follow the instructions to install ffmpeg-4

[qwangku]

I tried this command "add-apt-repository ppa:jonathonf/ffmpeg-4", but got the following error:

E: The repository 'http://ppa.launchpad.net/jonathonf/ffmpeg-4/ubuntu focal Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.

Could someone tell me how to get around this?
