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.

dig +short TXT {0..92}.vid.demo.servfail.network | sed --sandbox -- 's/[" ]*//g' | base64 -d -- | mpv -- -

    The bash backend is what made me stop. Compared to that a video-over-DNS sounds like a normal Tuesday.
