This is NOT a file format that corrupts itself. This is a file reader that corrupts files. There's a big difference. Nothing about the format itself causes or requires corruption. A better tagline would be "decayfmt is a social contract enforced by pinky promise".
Basically what you want is a custom PCIe device that can P2P DMA the DRM-encrypted frame data to GPU DRM-protected memory directly, more corrupted each time.
Can still be replayed, but would likely require special hardware to do so.
Tie::Hash::Cannabinol is a completely useless demonstration of how to use Tie::StdHash to
pervert the behaviour of Perl hashes. Once a hash has been tied to Tie::Hash::Cannabinol,
there is a 25% chance that it will forget anything that you tell it immediately and a
further 25% chance that it won't be able to retrieve any information you ask it for. Any
information that it does return will be pulled at random from its keys.
Oh, and the return value from exists isn't to be trusted either :)
From what I remember, MS Paint do something similar when you would save the image as a jpeg. It would apply the algorithm each save and the image would degrade a bit each time. It was super fun.
Seems like there is no mechanism to allow non-corrupting reads from authorized processes? Begs the question then of what the point of this is. Pure novelty, or truly something that could be used in practice?
A better analogy would be if every time you played the video file, the mechanism hallucinated a little, bringing in your current feelings as input to change the emotional undertones (and possibly characters and events) depicted in the video.
A company I was at had a disk array that would do something like this. It wasn't a documented feature mind you. During writes, it would randomly zero out data within a file. So at least it didn't get progressively worse, but it was a bear to isolate. These were large media files so a quick look at the head/middle/tail could easily miss the problem areas.

Dammit! This renders it completely unusable.
I came here for this comment.
"A file format that corrupts itself a little every time you open it" simply isn't possible.
It's almost like the author is trying to ragebait with this AI generated non-sense.
Reminds me of Tie::Hash::Cannabinol:

That happens with all editing programs for lossy formats, but it's on write, not on read.
> This is a social contract
What's the other side of the contract? Why would a reader oblige to corrupt?
Probably satire. Like: "social contract: you will allow fools to choose your government".

Kind of like how human memory works, if I understand correctly.

Should have patented it and licensed it to Snap
You might look into (Norbert) Weiner functions.
I thought something like this should be part of the file system to make it even more laborious to by pass

Would you please stop inventing more ways to enshittify the world?
