Recently I got tired and fed up with ubuntu/kubuntu and decided to go back to Opensuse 13.1. I installed it and almost everything works OK now. I do still have some troubles reanimating WIFI after sleep (I have to go to network configuration and enter my password for selected network). But this post is about video, so if you have chromium installed but youtube videos do not play then the following might help you solve your issue:
sudo zypper rm chromium-ffmpeg
The above will remove chromium-ffmpeg and will install chromium-ffmpegsumo. If you do not have chromium-ffmpegsumo installed then install it:
sudo zypper in chromium-ffmpegsumo
Hope this will help someone to make opensuse more enjoyable. Anyway even with these 2 annoyances I like opensuse more than ubuntu. (Maybe because I have not used it long enough yet:))
