Dear Eprints Tech Team,

I would like to ask for your help to integrate the video player to eprints3.

I followed these intructions:
https://wiki.eprints.org/w/Video_documents#Video_player
After, I insert these codes and I restart the Apache2, then I get "404 Not
found" http error.

I use Ubuntu 14.04 and Ubuntu 16.04. I installed the portal from your
repository. I tried to fix it by this:
https://wiki.eprints.org/w/Talk:Export_bar_on_abstract_page  ( I think,
it is a similar issue )

What cause this error? How can I fix it?

Best regards,
Attila DEBRECZENI
