I am also affected by the problem with the flickering video. May be my observation helps someone to find a solution or workfix.
I test it with LO 6.3.5.2 / LO 6.4.5 / LO 7.0.0.1 at ubuntu 19.10 with a simple impress document embedded a mp4 movie. Flickering appears in all versions at the full presentation screen. But, if I use the right mouse key in the presentation mode the control window (with Next, Got to Slide, ... menus) appears on the presentation screen and the flickering stops immediately. As long as the control window appears, the movie runs how it should be. Unfortunately the control window is to large for using this as a interim solution. May be, somebody can find a workaround to produce a smaller window with the mouse key, like this control window? Meanwhile I install a new ubuntu 20.04 LTS from scratch. Unfortunately the problem remains. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to libreoffice in Ubuntu. https://bugs.launchpad.net/bugs/1811530 Title: Impress embeded video files show flickering white stripes Status in LibreOffice: Unknown Status in libreoffice package in Ubuntu: Confirmed Bug description: Description: I have slide shows with embeded video files from previous versions of LibreOffice / Impress and they all worked well. If I play the video files with Ubuntu 18.04 and LibreOffice 6.0.7.3 they show flickering white stripes. the stripes are about 1 centimeter wide and move up and down in the picture of the video. Steps to Reproduce: 1. Embed a video file in a slide show. 2. Play the slide show / the video. Actual Results: The video plays but shows a disrupted picture with whiteish flickering stripes. Expected Results: The video should play as it is in a video player whithout a disrupted picture. It seems to be connected wit hardware acceleration, that is greyed out.
