Problem: vlc-noX-2.2.1-18.1.x86_64 requires libmatroska.so.6(V_1.4.1)(64bit),
but this requirement cannot be provided
 Solution 1: Following actions will be done:
  deinstallation of vlc-noX-2.2.1-18.1.x86_64
  deinstallation of phonon-backend-vlc-0.8.2-1.2.x86_64
  deinstallation of phonon4qt5-backend-vlc-0.8.2-2.3.x86_64
  deinstallation of vlc-2.2.1-18.1.x86_64
  deinstallation of vlc-qt-2.2.1-18.1.x86_64
  deinstallation of vlc-noX-lang-2.2.1-18.1.noarch
 Solution 2: do not install patch:openSUSE-2016-37-1.noarch
 Solution 3: break vlc-noX-2.2.1-18.1.x86_64 by ignoring some of its
dependencies

Reason is that the provides changed:

Provides (old):
  libmatroska.so.6()(64bit)
  libmatroska.so.6(V_1.4.1)(64bit)           <<<<<<
  libmatroska6 == 1.4.2-3.3
  libmatroska6(x86-64) == 1.4.2-3.3

Provides (new):
  libmatroska.so.6()(64bit)
  libmatroska6 == 1.4.4-5.1
  libmatroska6(x86-64) == 1.4.4-5.1

On openSUSE Leap 42.1, this affects:
