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 6.0.3.2 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. Reproducible: Always User Profile Reset: No Additional Info:
Two questions (three maybe). Types of video content and when you say from older versions of libreoffice, how old? I tried with a couple of Impress files made with 5.4.7, with 3 different videos types mp4 file with mp4 H.264, ogv with Theora and webm with VP8. They worked without a problem under 5.4.7 and 6.0.5, using Ubuntu 18.04. I got some older ones in a backup, 4.x versions, but I am interested in the video type in the file giving you problems. Thanks, setting this to needinfo for the moment.
It worked under Ubuntu 16.04 I can't remember which LibreOffice version was installed there. It doesn't matter what kind of video files as far as I figered out it happens to any kind of file. I uploaded an examaple here: https://ch.owncube.com/index.php/s/VaTbKwx9UkzKrEA In makind the example I figured out, that it happens to new presentations too. So it happens not only to old presentations but to new ones as well.

So it happens not only to old presentations but to new ones as well. IDK - that test file actually crashed both 6.0.5 and 6.1 in my environment. Extracted the media files, the two .flv files work fine stand alone, but the .mpeg crashes the media player in my OS every time (not just in Impress). Speaking of which if I create a new Impress file and drop in one of the .flv files the new impress file works fine and the video plays fine. If I try to add the .mpeg file, using 6.0.5 than Impress hangs. Also, trying to check the properties of the Billy Elliot.mpeg file crashed gnome 'Files' twice. so, it is looking like the mpeg file is the culprit and the OS support changed.

The .mpeg plays fine in Impress slideshow for me. No stripes, no crash.

On the other hand, I just tired opening that file with OpenShot and voila it is playing like a champ. Now I am scratching my head.
What have I started here? I just randomly picked a few video files all of which play fine with vlc and totem but show like all the rest of my video files the weird behaviour in Impress.

You have created a monster!! :) Please copy and paste here the contents of LibreOffice's Help - About. This allows us to know more about your system. You might also try with an appimage of a pre-release (6.1) or a daily build (6.2): https://libreoffice.soluzioniopen.com/

I just had a quick look, with the appimage of the pre-release all the tested video files worked as expected.
Ok, perhaps it is something related to Ubuntu and gtk3. Try this: 1. Open terminal 2. Give this command: SAL_USE_VCLPLUGIN=gtk libreoffice 3. Open your Impress file and see how the videos play Step 2 launches your Ubuntu-packaged LibreOffice so it uses gtk2 for the interface instead of gtk3.
the error doesn't go away if i open lO with gtk2. (It does show some improvement: the flickering stripes are now in black instead of in white ;-)
(In reply to rosgnilk from comment #13) > the error doesn't go away if i open lO with gtk2. (It does show some > improvement: the flickering stripes are now in black instead of in white ;-) Ah, then your appimage test proves that this is fixed in 6.1!
oh no, I gess it isn't planed that LO 6.1 lands in Ubuntu 18.04. That means I have to fiddle around with an manual upgrade to 6.1 which is allways a pain in the ass with ubuntu.
I just upgraded LO to 6.1 (ppa) but the bug doesn't go away, the videos still show the weird stripes. The same applies to the snap version.

Based on the results so far, this seems to be an Ubuntu-only bug. You should report it to them: https://bugs.launchpad.net/ubuntu/+source/libreoffice Tell them that the problem does not appear for you with the appimage. If in the future it turns out not to be strictly Ubuntu-only, we can change the status.
I think it is due to hardware acceleration: * Tools > Options > View > Graphics Output > uncheck "Use hardware acceleration" @Buovjaga I have a similar issue on fedora: https://ask.libreoffice.org/en/question/304553/white-stripes-on-screen/?answer=304554#post-id-304554
