Videos not working in Presentations 2024

[sebastian.schwindt]

Hello,

I tried to implement videos in my Presentation 2024 slides, but I keep getting the error message:
"Unable to play video (Probably missing codec.)"

However, the videos in the same presentation run when I open it with LibreOffice (just the formatting is ruined), and videos run with any other player, too. I tried several formats, and keep getting the error (the original file format of all my videos is .mp4).

I also tried the tip to run Presentations 2024 with `LIBVA_DRIVER_NAME=nvidia presentations24`through terminal, but the error persists. Can you please help me to figure out what is wrong?

Thank you!

AS the error says... You are missing a codec. Ensure you have all the gstreamer codecs (good, bad, ugly), as well as other codecs that are not part of of the gstreamer architecture: libx264, ffmpeg and so on. Mos distributions have an article explaining how to install all media codecs.
You may then ask: Then why does it work on LibreOffice? Well, most likely because or libreoffice looks for codec A and if it doesn't sees it looks for B, or has the codecs built-in.
The LIBVA_DRIVER_NAME won't do a thing because is not graphics related.

Thank you for the reply. I have installed any possible library on my Linux Mint (latest version), through:

apt install libavcodec-extra gstreamer1.0-vaapi gstreamer1.0-tools \
gstreamer1.0-plugins-base \
gstreamer1.0-plugins-good \
gstreamer1.0-plugins-bad \
gstreamer1.0-plugins-ugly \
gstreamer1.0-libav \
gstreamer1.0-x \
gstreamer1.0-alsa \
gstreamer1.0-gl \
gstreamer1.0-gtk3 \
libgstreamer1.0-dev \
libgstreamer-plugins-base1.0-dev \
ubuntu-restricted-extras

It still does not work with Presentations 2024, but with any other software that I have on my computer for presentations (ONLYOFFICE, LibreOffice, ...) . Can you please outline any specific library that Presentations 2024 may not include but all other software does somehow have implemented and that is not in the above list?
