I mixed “repo” and “codecs”. I understand that openSUSE can’t ship with proprietary software.
I’m following openSUSE 13.2 Multimedia Guide again now. How much of this stuff is actually mandatory after adding Packman and libdvdcss repositories?
As I’ve said, I don’t need Flash Player, can I remove “flash-player” from the following command?
zypper install libxine2-codecs ffmpeg lame gstreamer-0_10-plugins-good gstreamer-0_10-plugins-bad gstreamer-0_10-plugins-ugly gstreamer-0_10-plugins-bad-orig-addon gstreamer-0_10-plugins-good-extra gstreamer-0_10-plugins-ugly-orig-addon gstreamer-0_10-plugins-ffmpeg libdvdcss2 flash-player dvdauthor07 gstreamer-plugins-base gstreamer-plugins-bad gstreamer-plugins-bad-orig-addon gstreamer-plugins-good gstreamer-plugins-ugly gstreamer-plugins-ugly-orig-addon gstreamer-plugins-good-extra gstreamer-0_10-plugins-fluendo_mpegdemux gstreamer-0_10-plugins-fluendo_mpegmux vlc smplayer totem-browser-plugin h264enc x264 gstreamer-plugins-libav vlc-codecs
That depends on what software you are going to use.
This guide is intended as an “all-in-one” solution.
For VLC, you only need to install vlc-codecs.
But I’d advise to do that full switch to the Packman repo anyway.
This makes sure you don’t have a mix installed, and will replace some standard packages (like sox) with the “full-blown” versions that support all codecs.
As I’ve said, I don’t need Flash Player, can I remove “flash-player” from the following command?
Yes.
And probably others, too.
And if you really don’t want flash-player installed (or other non-free software), you maybe also should remove or disable the non-oss repo.
You can do so in YaST->Software Repositories e.g., or with zypper.
Or lock it in YaST->Software Management.
Be aware that this might pull in the alternative freshplayer-plugin and chromium-pepperflash though, which allows you to use Google’s Flashplayer in Firefox.
So you might want to lock those as well.
This all depends on what you exactly mean with “unwanted software” in the end, though.
Unfortunately I have to use non-free software.
Haven’t I already switched to Packman? I did this and applied to changes: https://dl.dropboxusercontent.com/u/10573557/Switcher%20Pics/13.1_Packman_Switch_Gnome.pdf
Shouldn’t playing protected content be already possible? I still haven’t got this fixed 
EDIT: I ran in terminal:
zypper install vlc-codecs
I finally understand. Packman doesn’t contain VLC codecs. Let’s see if DVD playback works correctly.
Yes, if you have the necessary codecs installed, and a consistent system.
That’s why I told you to run the switch again (“zypper dup --from 1”), and install vlc-codecs.

No, apparently you still didn’t fully understand.
Packman does contain “VLC codecs”, like it does contain VLC.
Otherwise you wouldn’t have been able to install them via “zypper install vlc-codecs”.
DVD playback should work now, unless there’s still another problem on your system.
And again, you do need libdvdcss2 installed for certain (encrypted) DVDs.
I understand now - adding the repository doesn’t install the content.
libdvdcss2 is installed.
No update candidate for 'libdvdcss2-1.2.13-5.1.x86_64'. The highest available version is already installed.
Correct.
A repository is just a pool or collection of packages, where you can install packages from.
Is libdvdcss absolutely necessary for watching DVDs, if I rip them first? Stallman says that he can “break” the DVD DRM and he has never used proprietary software.
It is not absolutely necessary for watching DVDs.
It is only necessary for watching encrypted DVDs.
It doesn’t matter if you rip them first. If you just do a 1:1 copy, you’d still need libdvdcss to play back the image.
If you rip them to another format, you’d need libdvdcss to rip them in the first place.
Stallman says that he can “break” the DVD DRM and he has never used proprietary software.
libdvdcss does “break” the DVD DRM, and is no proprietary software.
It’s open source and free actually, but as it circumvents the DRM, it is illegal in some countries.
