• Download youtube video as stream Readable object

  26 décembre 2023, par Abraam Emad

  in this function it download youtube video as a file out.mp4 on hard disk i need to download it as a Readable Object to upload it

  


  private async downloadVideo(videoId: string) {
// Buildin with nodejs
const cp = require('child_process');
const readline = require('readline');
// External modules
const ytdl = require('ytdl-core');

let progressbarHandle = null;
const progressbarInterval = 1000;
const showProgress = () => {
  readline.cursorTo(process.stdout, 0);

  process.stdout.write(`Audio  | ${(tracker.audio.downloaded / tracker.audio.total * 100).toFixed(2)}% processed `);

• ffmpeg 360 Video Conversion - EAC (Youtube) to Equirectangular

  18 juillet 2022, par chantey

  I have this top-bottom 360 Video, where the bottom is rotated 90 degrees clockwise, and I am looking for the ffmpeg command to produce a singular equirectangular output. I've been experimenting with various ffmpeg 360 filters, but am really just guessing at this point.

  


  

  


• How to use YouTube-dl to stream from Bloomberg TV ?

  Any help would be appreciated !

  This isn’t getting the correct stream from Bloomberg LiveTV, and I’m unsure why and how to fix.

  $ youtube-dl https://www.bloomberg.com/live

  Here’s a snippet of the errors that I get from that link :
