Hello im trying to play some videos with totem on CentOS 8.

I get the following message in the command line.

"totem
** Message: 17:22:06.269: Missing plugin: gstreamer|1.0|totem|MPEG-1
Video decoder|decoder-video/mpeg, mpegversion=(int)1,
systemstream=(boolean)false (MPEG-1 Video decoder)

(totem:12230): Gtk-WARNING **: 17:22:06.270: Drawing a gadget with
negative dimensions. Did you forget to allocate a size? (node slider
owner GtkScale)
"

I also get the following message.

MPEG-4 Video (Simple Profile) decoder is required to play the file, but
is not installed.


Any ideas what i have to install in order to play it?

Thanks in advance!
