Discord Crasher Detector

Check if a Video File will Crash the Discord Desktop Client

How It Works

Video URLs are first tested to see if they direct to a valid video file. If the url provided is a gfycat url, we request the video page from gfycat and extract the valid video url; The video is then analyzed using ffprobe-static, a static package with ffmpeg's ffprobe binaries If the video has properties that match those that crash discord, the analysis returns crasher: true

Installation

npm install discord-crasher-detector

Method

Detector.AnalyzeVideo

Analyzes video file at the specified URL | Parameter | Type | Optional | Default | Description | | --------- | ---- | -------- | ------- | ----------- | | videoUrl | string | | none | The URL of the Video | | generateMd5 | boolean | ✓ | false | Include MD5 checksum for the video | Returns: Promise<videoInfo>

Example Usage

const Detector = require('discord-crasher-detector');

let videoUrl = 'https://thumbs.gfycat.com/bluedampatlanticridleyturtle';
let analyze = Detector.AnalyzeVideo(videoUrl, true);
analyze.then((res) => {
    console.log(res);
}, (rej) => {
    console.log(rej);
});

Async/Await Support

const Detector = require('discord-crasher-detector');

async function runDetector(videoUrl) {
    let analysis = await Detector.AnalyzeVideo(videoUrl, true).catch((err) => {
        console.log(err);
    }
    if(analysis)
      console.log(analysis);
}
runDetector('https://thumbs.gfycat.com/bluedampatlanticridleyturtle');
