The default video player (Totem) is unable to play videos after installing Ubuntu 22.04. I tried opening an MP4 file and I get the error (also shown in the screenshot):
An error occured
The specified movie could not be found.
I also tried installing ubuntu-restricted-extras, but it's still not working.
This is a known issue for Ubuntu 22.04: Ubuntu 22.04 - totem 41.alpha.0 - The specified movie could not be found
There are also bug reports on Launchpad about it, which I suggest you subscribe to, so that they get more heat and hopefully get dealt with more quickly:
The workaround for the moment is to either use the Flatpak version of Totem or another video player, such as VLC, mpv, etc.
Update 23/05/2022:
As Samuel Simon commented in 19/05/2022 in the first bug report above:
Run this command:
sudo apt remove gstreamer1.0-vaapiGot my solution from this article, check it out too. https://www.makeuseof.com/things-to-do-after-upgrading-to-ubuntu-2204-lts/
Thanks @Manuel for mentioning this workaround in their answer.
As pointed in the second link of the answer given by @BeastOfCaerbannog, a solution for PCs (no Raspberry Pi, as pointed in the same thread) is to remove gstreamer1.0-vaapi:
sudo apt remove gstreamer1.0-vaapi
Here is the original article.
I tried to remove gstreamer1.0-vaapi, but that also didn't work. I read from an Ubuntu bug report that I should use something like:
MESA_GL_VERSION_OVERRIDE=3.3 totem
So I played with 3.3, 3.2, until this worked for me using the shell:
MESA_GL_VERSION_OVERRIDE=3.1 totem
My system's details:
Videos had been problematic on 22.04 since installing it. Symptoms are Video starting 10 seconds after audio, and Video stalling, especially when stopping and resuming a video. Confirmed on Ubuntu 22.04 and XUbuntu 22.04 All streaming videos were affected, not just netflix.
I also have similar problems in 23.10, but not on 22.04 Lubuntu.
my hardware: Gigabyte RTX 3060 on an asus Z690P motherboard. Using s/pdif output.
Maybe what I've found so far will give someone knowedgable on audio and video driver interactions a clue where to look. the key value seems to be -10 seconds, probably stored as a value around -10,000 milliseconds but the setting in Pulse Audio is only -20.00 ms.
A workaround. Maybe... An upstream fix that made it into the latest drivers?
I updated Xubuntu today. The updates included several drivers including Nvidia. Yhe problem seems to be resolved. After a reboot, the videos played normally. I'll update this post if anything changes.

I installed Ubuntu 22 and ran into trouble playing some udemy training videos, so I looked to troubleshoot and came across this question. I tried uninstalling
sudo apt remove gstreamer1.0-vaapi
but that did not work as I didn't have that package installed.
When trying to troubleshoot I learned of a few things which I will share:
I found this command:
aplay /usr/share/sounds/alsa/Front_Center.wav
worked out of the box (no other installs)
I found this website
https://sample-videos.com/index.php#sample-mp4-video
that had some MP4 files which I could download for testing.
I tried opening the file using the Ubuntu File Explorer (I think it is called Nautilus). But I got the same error the OP pointed out but there was a popup that said something like Install from the Ubuntu Software Store. The GUI looked like this, and I installed all of the choices that were not greyed out.
This didn't work, the video still did not play.
The solution (for me) was to install vlc. After I installed vlc using
sudo apt install vlc
Then both vlc SampleVideo_1280x720_20mb.mp4 worked, but also double-clicking on the file icon in the File Explorer also worked (and opened a different video player).
