Hello! Need some help, please: how to force Totem-player to display video on .mkv files? Sound works ok, but video-stream is absent. Gstreamer+plugins is installed from official openSUSE repo. Thanks!
the “official” gstreamer does not contain patented codec for that you need packman
so do this, (you can copy paste)
sudo zypper ar -f http://packman.inode.at/suse/openSUSE_Leap_42.1/ packman
sudo zypper dup --from packman
Done. But everything is the same – sound is ok and video-stream is not ok.
try opening it in vlc or mplayer
maybe your gstreamer cache is damaged try removing the gstreamer cache
rm -r ~/.*cache*/*gstreamer*-1.0/
what graphic card do you have, some intel chips have issues with vdpau?
And also make sure that gstreamer-plugins-libav is installed.

Didn’t help.

O! 
This helped! Thanks to everybody, who gave tips 
P.S. Possibly, it will be nice if gstreamer installs this lib by default…
