First of all, thanks for creating LO Impress. It is a good alternative to PowerPoint for me. :)

Nevertheless, I have a problem: LO Impress does not play MP4 files encoded as h264. But, Impress plays videos with the royal-free codec Theora. See the following screenshot: Slide two contains the OGV video, slide three contains the MP4 video (but only shows the placeholder symbol).

LO Impress does not play MP4 files

According to this forum post, "LibreOffice relies on the operating system's installed media support", and it also suggests to install the package libreoffice-avmedia-backend-gstreamer. Therefore, I have installed following packages:

gstreamer-qapt gstreamer1.0-plugins-base gstreamer1.0-plugins-good gstreamer1.0-plugins-ugly gstreamer1.0-pulseaudio gstreamer1.0-x libreoffice-avmedia-backend-gstreamer phonon-backend-gstreamer phonon-backend-gstreamer-common phonon4qt5-backend-gstreamer

For test purposes, I have also installed the VLC backends with no success:

phonon-backend-vlc phonon4qt5-backend-vlc

ffprobe reborts following information about the MP4 and the OGV file:


MP4 File:

Stream #0:0(eng): Video: h264 (High) (avc1 / 0x31637661), yuv420p, 522x536, 138 kb/s, 25 fps, 25 tbr, 12800 tbn, 50 tbc (default)

OGV File:

Stream #0:0(eng): Video: theora, yuv420p, 522x536 [SAR 1:1 DAR 261:268], 25 tbr, 25 tbn, 25 tbc


My environment:

  • OS: Kubuntu 18.04.1 LTS
  • LO Impress Version:

So, whats going wrong? Any hints or suggestions?
