VLC player is not part of standard openSUSE repositories, so we have to add additional repository for VLC and its tools:

$ sudo zypper ar http://download.videolan.org/pub/vlc/SuSE/Leap_15.0/ VLC

For openSUSE Leap 15.1 output of command for adding repo was following:

      90 (raised priority)  :  2 repositories
      99 (default priority) : 11 repositories

Installing VLC

When new repository was added, we can simply install VLC running two commands:

$ sudo zypper mr -r VLC
$ sudo zypper in vlc

In case you're missing some libraries or packages, system will ask to you install them.
