Thank you, this resolved my issue.

I read the wiki and changed “Hardware-accelerated decoding” to “VA-API video decoder”.

My original problem was caused by the fact that this was set to automatic, now that it’s set to “VA-API video decoder” VLC is able to play mp4 files again without any issues.

I disabled hardware acceleration and VLC is able to play mp4 files again; however, is there a way to turn on hardware acceleration without getting these errors?

Update:

Changing “Hardware-accelerated decoding” to “VA-API video decoder” fixed the issue. Now VLC is able to play mp4 files with hardware acceleration without any issues.

Tried it. I don’t think there’s anything to upgrade:

Jean-Luc@Enterprise:~$ sudo apt dist-upgrade
[sudo] password for Jean-Luc: 
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Calculating upgrade... Done
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

How do I do that?

I don’t know if it updated my video driver. I just used this command: sudo apt update && sudo apt upgrade

like Debian Stable has packages from this century

You can set up Debian 12 to use Flatpak. I use it and it works well.
