Due to proprietary reasons and such some packages do not get installed on new Linux installs. Among those is the FFmpeg as it is needed to help fully support HTML5 players on websites.
This page mostly does what the old youtube.com/html5 page is telling you if you support all six things or not. https://www.jeffersonscher.com/sumo/html5-video.html
Thank you.
