I installed libvdpau-va-gl and intel-media-driver and rebooted and still no luck. libva-intel-driver was already installed.
When running VLC from the command line I get no errors, but the image still does not move. When quitting VLC I get (opening an mp4 file):

With mpv I see no errors in the console, but still no moving pictures.
Oh! Knowing it had worked until recently triggered a thought. By recently, would that be today? The libplacebo pkg was updated today.

From the last error, it looks like you have v5.229.2, so you could try to downgrade it to the previous.
At the moment, that seems like it would support the theory that downgrading the libplacebo library will help. There are still other factors at play between the ISO and bare metal, so that might only be wishful thinking.
Edit:
I also use i3, but on a HP Omen Optimus laptop. I did find an mp4 in my library, and it plays in mpv on my system. As I am using nvidia, this doesn’t really provide much help as to whether it is libplacebo, or still hunting a missing lib or config, unfortunately.
Sounds like you figured out how to compare and find the differences for ISO and installed files.
Glad to hear you got it working. Not sure why it would have stopped working for you, but you might take a look at Arch Wiki Intel, to see if you can get direction for any of the remaining errors.
Thanks. That looks very technical. It works so I stick with what I have now. I am sure any issues will fix themselves in future updates. I don’t know enough about hardware to properly troubleshoot this issue.
Postscriptum: I did a fresh install, removed xf86-video-intel, rebooted and presto.
