Since creating this bug report I have reinstalled openSUSE Tumbleweed and I am
now using i3wm. I am currently using VLC with wine to watch any videos.

I believe I have installed all the required codecs that are needed to play h264
videos.

Here are the outputs of the commands you listed, I have replaced the actual
file paths with "/path/to/video.mkv":

daniel@localhost:~> file /path/to/video.mkv
/path/to/video.mkv: Matroska data

daniel@localhost:~> gst-olay-1.0 /path/to/video.mkv 
If 'gst-olay-1.0' is not a typo you can use command-not-found to lookup the
package that contains it, like this:
    cnf gst-olay-1.0


Here is also the output from trying to play the video using MPV.

daniel@localhost:~> mpv /path/to/video.mkv
Playing: /path/to/video.mkv
 (+) Video --vid=1 (*) (h264)
 (+) Audio --aid=1 --alang=eng (*) (aac)
     Subs  --sid=1 --slang=eng (subrip)
