Did not fix VLC codec problems. Come on if VLC is installed then it should play videos especially MP4s. Since their website says “VLC is a free and open source cross-platform multimedia player and framework that plays most multimedia files “How about some common sense defaults. Why do I have to Google to get this to work? My 1st experience with Tumbleweed after a long absence was very positive. Now it’s turned to crap. And this problem has nothing to do with KDE.
