This is your Github page and telling others not to abuse this? Get a grip dude.

found a way to do this with ffmpeg and using a input image, making it into a webm, fun stuff! This is nice also since it works in firefox :D

ffmpeg -loop 1 -i image.jpg -t 5 -c:v libvpx-vp9 -pix_fmt yuv420p -color_primaries bt2020 -color_trc smpte2084 -colorspace bt2020nc -metadata:s:v:0 master-display="G(8500,39850)B(6550,2300)R(35400,14600)WP(15635,16450)L(50000000,10)" output.webm

and for just a blank image

ffmpeg -f lavfi -i color=c=white:s=240x240:r=1:d=1 -c:v libvpx-vp9 -pix_fmt yuv420p -color_primaries bt2020 -color_trc smpte2084 -colorspace bt2020nc -metadata:s:v:0 master-display="G(8500,39850)B(6550,2300)R(35400,14600)WP(15635,16450)L(50000000,10)" blank.webm

got the display values from https://silentaperture.gitlab.io/mdbook-guide/encoding/x265.html?highlight=master-display#source-dependent-settings

edit: changed unneccessary 30 fps framerate to 1 fps, thanks @notpushkin

And make a QRImage in photoshop with avifenc (https://github.com/AOMediaCodec/libavif).

What is this called on my macbook and is there a way to turn it off? I occasionally see this happen with photos I take on my Pixel and share via the web. It's very annoying
