I have found a solution to this problem that works for me at: https://ask.libreoffice.org/en/question/157815/impress-6-in-ubuntu-1804 -video-playback-only-as-full-screen/
To me it looks like it is related to one of the gstreamer1.0-plugins-* not being included in the packages for LibreOffice 6.1.3.2. I have not tried to locate the missing packages and I hope someone in this site can locate the packages. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1789029 Title: Impress embedded video takes full screen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libreoffice/+bug/1789029/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
