Interesting, I have never tried this before.

I’ll try out your solution and get back to you.

Thanks

For me sites like YouTube, Rumble, Odysee, and Bitchute work but unfortunately this version of flatpak Firefox is giving me problems.

It uses Google’s Chromium engine, that’s the problem.

I appreciate your recommendation but I’m boycotting Google and as much of its tech as possible—that’s why I was using Firefox.

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.
