How it Works

Getting the Audio & Video Data manually

In my case I use the yt-dlp tool to download the video and ffmpeg to extract the audio track.

• the video is saved in the src/utils/assets folder as badapple.webm to be processed later.
• the audio track is saved in the src/data folder as track.ogg to be used by the animation.

yt-dlp https://www.youtube.com/watch?v=FtutLA63Cp8 -o ./src/utils/assets/badapple.webm
ffmpeg -i ./src/utils/badapple.webm -vn -q:a 4 ./src/data/track.ogg

Converting the Video to SVG paths

We process the video using edge detection (Sobel operator) and contour finding technique (thresholding) to extracts polygon points. After iterating over all the frames, we save all polygons in a JSON file.

• the JSON file is saved in the src/data folder as frames.json to be used by the animation.

Requirements

• OpenCV
• Numpy

cd ./src/utils
python3 polyframe_extractor.py ./assets/badapple.webm 

Playing the Animation

Just a simple DOM manipulation to change the path of the SVG element synchronously with the audio track and original video frames rate.

const svg = document.querySelector(".js-activity-overview-graph");
const svgPath = svg.querySelector("path");
...

function getPathFromPolygons(polygons) {
    return polygons.map(polygon => `M${polygon.join(" L")} Z`).join(" ");
}

Minified Code

Code minified using minify.

cd ./src
minify badapple.js > badapple.min.js
