Forked:

  • Downloads highest quality available
  • Combines audio and video together using ffmpeg (make sure ffmpeg is installed before running)

Works great , but I'm downloading on low quality video , as @jangxx suggested .

const videoData = json.video.find(v => v.height == 360); // or 1080, or something else

Hello, I download the audio and the video well but I am having problems with ffmpeg, I installed on the macBook through homebrew and when launching the script it failed me. I am trying to mix .m4v and .m4a extension files. Do I need to install something else?

this is the version -> ffmpeg version 4.4 Copyright (c) 2000-2021 the FFmpeg developers
and this is the log:

Unfortunately I do not have the time to look into this right now. You may try combining video and audio externally, or search ffmpeg forums about this. It seems like the downloaded content is not in .m4v format. I would suggest replacing every instance of ".mp4" with other common video file extensions and see if you can find the correct one. You could also analyze the downloaded video-only with the file command and deduct the correct extension that way. I've updated the script so it does that automatically in case ffmpeg crashes. This should help you figure out what is happening here.
