Lots of Internet says to "add-apt-repository ppa:jonathonf/ffmpeg-3" for good ffmpeg, but don't if you're bionic (ubuntu 18). Instead, press "add-apt-repository ppa:jonathonf/ffmpeg-4". Also probably remove the old one with "add-apt-repository -r ppa:jonathonf/ffmpeg-3"

... and if, in a moment of weakness, you installed ffmpeg to /usr/local, nuke that, and don't forget the libs! If /usr/bin/ffmpeg keeps barfing, search and destroy the results of "ldd /usr/bin/ffmpeg | grep "/usr/local/lib"

"... but how did you know ffmpeg was broken if you weren't even trying to run it?!" Simple, I watched my dang mastodon logs to learn that I'm OUT OF COCAINE. Then I went out and got some.
