If you can wonder why you can play vids on youtube, but need to  do additional shit to play vids on sites like Reddit, Facebook, Twitter etc. I will basically give you two words HTML5 and h264, don’t bother asking me anything about those subjects 

I had to Google like crazy to find the solution, hence I am creating a post. Credit goes to gman1  ⭐  he shared his solution on here. I was drunk (yeah I know 🙄  go fuck yourself now) when I fixed the problem. So the usual screenshots, are missing 💡

What you basically have to do is, fire up terminal paste the following code and follow the instructions on your screen.

su

When asked type your password. Then type the following commands:

dnf install https://download1.rpmfusion.org/{free/fedora/rpmfusion-free,nonfree/fedora/rpmfusion-nonfree}-release-$(rpm -E %fedora).noarch.rpm

dnf install ffmpeg-libs compat-ffmpeg28

This last command adds the codecs/plugins in your Fedora system, so you can play all vids in Dragon Player for example.

dnf install gstreamer1-libav gstreamer1-plugins-ugly
