I use Impress presentations with embedded media files (audio and video) for online lectures very often. I let my audience download the files because I use audio/video conference systems like Mumble without screen sharing. Unfortunately a lot of users reported that slides with embedded media files didn't play the audio or video content. As far as I understood...
...LibreOffice impress media files are only played if the operation system supports the embedded file format. I don't think that this is really the case because a presentation with media files created under Debian GNU/Linux is not properly played in a Linux Mint system although the used media files were played on the Linux Mint system.
However: Thank you very much for Libre Office!

One slide impress presentation with an embedded WebM video.
The attached one slide impress presentation with an embedded WebM video was created under Debian 10.9 and LO 220.127.116.11 ("source system"). After transferring this presentation to a Linux Mint 19.3 system with LO 18.104.22.168 ("target system") the video in the presentation is not visible, just the sound of the video is hearable.
If I play just the embedded video file on the "target system" the video content is visible and hearable so the target system is able to play the video.
[Automated Action] NeedInfo-To-Unconfirmed
No repro Win.
Repro 6.1 master, no repro 6.2 and 6.3 master and 6.4 oldest (ODS open and webM fine), somewhat repro 6.4 master (ODS opens black but webM runs OK) and 7.3+ (as in 6.4) Linux Mint 19 GTK3. No repro with GEN and SKIA.
Not sure if regression in GTK3 or just some flopping.
I tried bibisect in 6.4 but with no success. I considered black screen already when prez is opened as repro. But still runs video in 6.4 so I guess that spoiled it.
Someone else may also try.
Upon retest, I don't know why I confirmed this. Let someone else test.
Do you have package gstreamer1.0-gtk3 ? As in bug 124068.

Meanwhile I've set up my main system with a freh Debian11/bullseye installation so I don't know if it was the case before. Now the situation on my system is
$ apt policy gstreamer1.0-gtk3
*** 1.18.4-2 500
500 http://deb.debian.org/debian bullseye/main amd64 Packages
and the media in the attached video of https://bugs.documentfoundation.org/attachment.cgi?id=172848 is played as expected.
Do I have to test again the situation with a random target system like before and does a target system need gstreamer1.0-gtk3 installed to play the embedded media files properly?

No need to test, thanks. I guess we can call this notourbug as it's a packaging dependency issue of your distribution.

So the problem is caused by LO compiled for Debian and not by Windows/Linux/MacOS LO versions opening a presentation with media files?

It is caused by LibreOffice packaged for Debian not installing that gstreamer package as a dependency. Windows and macOS are not using a package manager to install LibreOffice.
This should be reported to Debian or Ubuntu.
I see in my Mint based on Ubuntu that libreoffice depends on some gstreamer packages but not on gstreamer1.0-gtk3, while it should in GTK3.

So I have to report the problem to the Debian and Ubuntu developers?

Yes, because this is a packaging issue.
