Comment 2 for bug 1839542

I ran the following the try and install what appears to be a missing gstreamer package:

sudo apt update
sudo apt install libdvdnav4 libdvdread4 gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly libdvd-pkg
sudo apt install ubuntu-restricted-extras

https://websiteforstudents.com/how-to-install-video-audio-codecs-on-ubuntu-18-10-18-04-16-04-lts/

I still don't see the image previews inside my WDMyCloud webpage.

Now the debug report shows:
