Terminal Install Method
Open a terminal like konsole or whatever terminal application you prefer.
This can be done by pressing the Meta / Superkey or Alt+F2 and typing in either “terminal” or “konsole” when using Plasma. Gnome users can just start typing while on the desktop.
The first Step will be to Add Repositories and to do this, copy and paste the following lines carefully choosing the distribution version to what you are running

Continue Here for ALL versions
Once complete you will have to refresh the repositories by copying and pasting this:
sudo zypper ref
This is going to require some user interaction from you. You will have to agree to some things. The first will be the AdobeFlash repository, it is “unsigned”. If that is not going to work for you, you can decline.
The Mozilla, Packman and libdvdcss will provide certificate keys that you need to determine if you want to reject (r), trust temporarily (t) or trust always (a). I recommend you select a for trust always.
I recommend making the Packman repository your primary source for multimedia libraries. You are less prone to issues with your multimedia files:
sudo zypper dup --allow-vendor-change --from Packman
Now you can install all the programs. Copy and paste this command:
sudo zypper in flash-player gstreamer-plugins-base gstreamer-plugins-good gstreamer-plugins-good-extra gstreamer-plugins-base gstreamer-plugins-good gstreamer-plugins-libav gstreamer-utils faac faad2 x264 lame ffmpeg lame phonon4qt5-backend-vlc vlc-codecs libdvdcss2 vlc
sudo zypper in gstreamer-plugins-ugly gstreamer-plugins-bad gstreamer-plugins-bad-orig-addon
