Bad Apple on Wooting

Tested on Wooting two HE ARM.

Requirements

Install wooting-rgb-sdk. On arch, it's available in the AUR.
Enable udev rules for wooting if you haven't done so (you can install wootility-lekker from AUR which contains the rules). You will need to run the app as root if you don't.
For compilation, just run cargo build (called automatically when running with cargo run). If you don't have rust installed, you can install it with rustup.

Playback

App reads from data/resized and displays each image (sorted by ASCII) for 1/30th of a second on the keyboard directly. This requires the image to be resized correctly as the app doesn't do any resizing.

To set up your video, create the data folder, download your video there, extract frames with ffmpeg and resize them with imagemagick:

The following is a fish script I used:

mkdir data && cd data
yt-dlp <video URL here> # check for legality in your state :)
ffmpeg -i <video file> -r 30 data/%04d.png
for i in (find out/ | string sub -s 5);
    magick out/$i -resize 7x6! resized/$i;
end

Bad Apple for example can roughly be translated to a 7x6 grid (6 is height, which is the same as the number of rows on the keyboard). the ! force resize to the specified size.

Then start the command - if you have the repository clonned locally, use cargo run (rust required, see rustup for installation of rust), or run the binary.
