Ok, I understand. Sorry.

For those who use Debian or Ubuntu, try this package:
chromium-codecs-ffmpeg-extra_75.0.3770.90-0ubuntu0.19.04.1_amd64.deb
I'm not sure if package installation will help, but the library from the package will.
The DEB , RPM , xz packages can be opened e.g. by Ark or others unzippers.

Other working example for Arch users:
opera-ffmpeg-codecs-75.0.3770.100-1-x86_64.pkg.tar.xz

A libffmpeg.so file from both packages works also in Fedora 30.

To install codecs in a proper way for a particular distribution there must be a good guy who will pack it.
Today I only know a workaround - copy library from package to the system library directory.
