Since a few days I can't play videos, system wide.
I am running this help: So installieren Sie alle Multimedia-Codecs unter Ubuntu Linux | CodePre.com
Then the videos work again for a short time, but then not again.
How can I fix this error?
Hello greenster
Have you tried using "vlc"? 
Yes, VLC plays videos, but no videos are played in several browsers.
Hi Greenster,
If you can't watch youtube, it is definitely not a 'ubuntu-restricted-extras' problem.
If you disable video hardware acceleration in your browser settings and it is still not working then we really need more info.
To get some extra info, run the following commands and paste the results here, we might need more later on:
inxi -CGz
snap list
dpkg --get-selections {*firefox*,*brave*,*chromium*,*opera*}
cat /etc/*release
The info we get from the aforementioned commands could at least give us some insight in what kind of install we are looking at.

Thank you very much for your help. But strangely enough, it currently works to watch YouTube and other videos. If the error occurs again, then I will implement your suggestions. I use Vivaldi browser as default, but also Firefox and Chromium for testing.
The error occurs again.

Hi greenster 
I've more or less simulated your setup on an old laptop.
The first time I started Firefox (snap) and visited youtube, it refused to connect to youtube and displayed a certificate error, hence I couldn't connect and I couldn't watch video.
Exactly the same happened to chromium.
Some time later it just worked.
With the small amount of info that I have I suspect that this is a certificate- or https handshake error where I presume that the communication with the certificate-issuing party times out or something comparable. So I have some questions:
-
If it happens again with youtube, could you try to see if Odysee has the same problem ?
-
If youtube refuses to play on your browsers
Could you try to let your browsers play a locally stored video instead of an online one ?
(only use WEBM videos or , if you dont have locally stored WEBM, a youtube compatible format like MP4 containing AVC + AAC )
It would confirm the suspicion that the problem is network related. -
Has your internetspeed been fluctuating more than ever recently ?
-
Has there been any machines digging in the streets in your neighbourhood ?
-
Is there any specific day ( or time ) that your videoplay stops/starts working (rush hour)?
-
Have you visited any more sites lately that gave a certificate error ?
Only VLC plays videos offline.
Odysee is like youtube but a lot less demanding with respect to javascript, beacons, XHR etc etc. So if something doesn't work with Odysee it will probably work nowhere

Odysee also does not play videos.
Is it possible that my graphics card has a problem?
Okay, so your browsers don't play any online videos but also no offline videos.
VLC (and probably other mediaplayers too) play without problem.
Since the mediaplayers play video, your standard codecs are provably working and so is the rendering path to your video output. (so it is not a graphics card problem)
Browsers need codecs as prepackaged browser-addons (almost always prepackaged with the browser). I am afraid that I'm no expert on that. Sorry.
Last resort:
sudo apt install ubuntu-restricted-addons
If that doesn't work, I'm out of solutions, I give up. 
"sudo apt install ubuntu-restricted-addons" was already installed, but thanks for your help.
I enabled pre-release updates and after that there was a big update and now the videos in the browser play again
