Useful trick

[josedotjs]

Hello Khalid, thanks for this project. Im doing a similar software and i have a trick to share. You can use ffmpeg to download only the portion of the video that you need. Consider this example

const ytdl = require('youtube-dl')
const ffmpeg = require('fluent-ffmpeg')

let options = ['-f 18', '--get-url'];
let url = 'https://www.youtube.com/watch?v=zJ7hUvU-d2Q' // 6 hours long video

ytdl.getInfo(url, options, function(err, info) {
  if (err) {
    return
  }
  ffmpeg(info.url)
  .seekInput('0:20:30') //work best with this format
  .duration(20) //seconds
  .save('outfile.mp4')
})

This helps to save a lot of time and bandwidth in large videos.
I hope this helps
