[Wlug] OpenSUSE updates

I'm having trouble with unresolved dependencies when trying to get updates with Apper in OpenSUSE: nothing provides libvpx.so.3()(64bit) needed by libavcodec56-2.8.6-55.1.x86_64 nothing provides libgnutls.so.30()(64bit) needed by libavformat56-2.8.6-55.1.x86_64 nothing provides liblzma.so.5(XZ_5.0)(64bit) needed by gstreamer-plugins-libav-1.6.1-2.1.x86_64 Is it just a matter of finding the right repositories? Can anyone point me in the right direction? -- Thanks! Rich
