This worked on Ubuntu 20.04.1 with Opera 72
Install the "Chromium Ffmpeg codecs" snap via the "Ubuntu Software" app

Then, on the command line, let's find the libffmpeg.so library that was installed by the chromium snap
$ locate libffmpeg.so
/opt/Postman/Postman-1605981456437-old/libffmpeg.so
/opt/Postman/app/libffmpeg.so
/opt/Postman.bak/app/libffmpeg.so
/snap/chromium/1399/usr/lib/chromium-browser/libffmpeg.so
/snap/chromium/1411/usr/lib/chromium-browser/libffmpeg.so
/usr/lib/slack/libffmpeg.so

We want the latest chromium one. Plug that path into the next step

$ cd /usr/lib/x86_64-linux-gnu/opera; sudo mv libffmpeg.so libffmpeg.so.bak; sudo ln -s /snap/chromium/1411/usr/lib/chromium-browser/libffmpeg.so

This app is quite nice. At the time of my writing this, it was a little rough around the edges, but I successfully worked with an 8GB heap dump. I was able to find my issue with this while VisualVM crashed. (I still like visualvm a lot though).
