I have tried the way I prefer and followed the “Additional multimedia codec support for SLED 12” instructions from mikewillis.
Everything builds correctly as far as I can see and gst-inspect-1.0 shows a lot of plugins afterwards (about 180 I think).
Any suggestions to how to double check that the codecs actually builds and works as expected?
I have also tried to install codecs and plugins from openSUSE / packman repos, which I would prefer not to do.
Anyway that has not worked either.
Finally I have tried the One Play Codec Pack from Fluendo, which install correctly as well.
However that doesn’t make any difference in Firefox either.
I have been around about:plugins, about:config etc. and tried all suggestions from google.
Apparently I am missing something.
Any help is much appreciated!
