It turns out you can get video over DNS TXT records.
I saw “we made a globally distributed DNS network for shits and giggles” at 38c3.
It can also be found on one of the presenter’s webpage.
The presenter of “A Deep Dive into DNS” mentioned that some people have used TXT records to perform backups, so it was interesting to see that in action.
Obligitory bash warning: I added the --sandbox to sed and the “end of options” -- flag to the utilities that support it for security, but really, it depends on how much you trust mpv and the people who gave the talk I suppose, so be careful.

Lmaoo the webpage has a prompt injection
I’m sorry. I didn’t read the whole page. Just the part about video-over-dns which was covered in the talk.
Are you talking about that weird logo and do you recommend I remove the link?
Oh, I see the part that says “Delist…”. I did see that. I guess I was used to hearing “prompt injection” with regards to the LLM web prompts versus something that crawlers would use that I was worried I’d made a mistake sharing.
Wait, can you go into more detail? I don’t feel like reading the entire thing as it’s not really my area of expertise
