First time I opened something with webscreensaver it said I had no webkit installed, or something like "namespace webkit not available", message was in yellow. Searching a bit, I found I needed this: gir1.2-webkit-3.0. Installed it, worked fine until I tried to play a video. The video works in Chrome and Firefox, but not in the webscreensaver.
All I know for now is that it uses this user-agent, not sure if this can help someone to help me:
Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/538.15 (KHTML, like Gecko) Version/8.0 Safari/538.15

Also I'm using this HTML+JS https://github.com/archagy/webnuxsaver, should I post this issue there as well?

Hi there, I think this might be due to the video format? It really depends on what gtk webkit supports in terms of codecs -- it's not exactly the same as Chrome or Firefox, unfortunately!

Using "sudo apt-get -qy install ubuntu-restricted-addons gstreamer1.0-plugins-ugly" I managed to get it working for the Raspberry Pi and on a Ubuntu PC.

I do however run into another issue using Video. It keeps hanging in the process list after a signal churning ~40% CPU. This is also reported by xscreensaver that the previous process did not quit untill the video stops looping.

xscreensaver: 15:36:12: 0: destroyed old saver window 0x1200052.
xscreensaver: 15:36:12: WARNING: pid 6385 (webscreensaver) sent SIGTERM 67 seconds ago and did not die!

I do see other references to Gtk.main_quit() not working as expected, but unfamiliarity with Python code prevents me from fixing this myself. I added a os.system() under terminate, but it fails to reach that too.

Depending on how the plugins run (subprocesses but detached in terms of pid group?), this could be a bit of a tricky beast to solve.

I will try and an run this thing in a VM and bump the gtk webkit version and see what happens!

We ended up using webscreenssaver with pictures, that works as intended. It wasn't really intended for a looping video, but it works nonetheless. Just don't quit the screensaver too often :)
