Web 3.28.1 No Video

[Adam Hunt <gander22h gmail com>]

I am running Web 3.28.1 on Lubuntu 18.04 LTS, installed from the distro repositories. I do not have Adobe Flash installed (non-free software) and instead rely on HTML5 video. This works fine in other browsers such as Firefox, Chromium, etc, but Web 3,28.1 will not play video, such as YouTube, Vimeo, etc. When attempting to play video the audio plays fine, but the video image is missing.

In past versions of Lubuntu, the installation of video codecs from the ubuntu-restricted-addons resolved video issues and allowed earlier versions of Web to play videos, but that package now contains only chromium-codecs-ffmpeg-extra, gstreamer1.0-fluendo-mp3, gstreamer1.0-libav, gstreamer1.0-plugins-ugly and gstreamer1.0-vaapi and testing seems to indicate that this does not allow videos to be played on Web 3.28.1.

A reply on the Ubuntu Forums https://ubuntuforums.org/showthread.php?t=2392660 suggested:

sudo apt -y install libdvdcss2 ffmpeg
sudo dpkg-reconfigure libdvd-pkg

But that did not solve the issue.

The HTML5 test shows under "Video":

video element Yes ✔
Subtitles Yes ✔
Audio track selection Yes ✔
Video track selection Yes ✔
Poster images Yes ✔
Codec detection Yes ✔

Video codecs
MPEG-4 ASP support No ✘
H.264 support No ✘
H.265 support No ✘
Ogg Theora support Yes ✔
WebM with VP8 support Yes ✔
WebM with VP9 support Yes ✔

Any solutions?
