• Download billboard hot 100 (but only 50) mp3 files

  4 mars 2021, par Atlas

  Yo yo yo. I got this insane idea to get 50 of the billboard hot 100 songs, download them into mp3 files, and then put them on private online radio.

  


  Problem is, the way I do it doesn't download each file one by one, it puts all the music together in one mp3 file. Here's my code so far (terrible, I know... I just wanna throw this together really quickly)

  


  const { getChart } = require("billboard-top-100");
const ffmpeg = require("fluent-ffmpeg");
const { mkdir } = require("fs");
const ytdl = require("ytdl-core");
const YT = require("scrape-youtube").default;

getChart('hot-100', (err, chart) => {
    if(err) console.log(err);
    chart.songs.length = 50;
    for (var i = 0; i < chart.songs.length; i++) {
        var song = chart.songs[i];
        song.artist = song.artist.replace("Featuring", "feat.");
        var name = `${song.artist} - ${song.title}`;
        YT.search(name).then(res => {
            downloadVideo(res.videos[0].link, name).then(_ => { console.log(""); }).catch(console.log);
        }).catch(err => console.log(err));
    };
});

function downloadVideo(url, name) {
    return new Promise((resolve, reject) => {
        var stream = ytdl(url, { filter: "audioonly", quality: "highestaudio" });
        var start = Date.now();

        ffmpeg(stream)
            .audioBitrate(128)
            .save(`${__dirname}/${new Date().getWeek()}/${name}.mp3`)
            .on("end", _ => {
                console.log(`Downloaded "${name}.mp3" - Took ${(Date.now() - start) / 1000} seconds.`);
                resolve(`${name}.mp3`);
            })
            .on("error", _ => reject("something went wong"));
    });
}

Date.prototype.getWeek = function() {
  var onejan = new Date(this.getFullYear(),0,1);
  return Math.ceil((((this - onejan) / 86400000) + onejan.getDay()+1)/7);
}


  


• FFmpeg conform DASH to YouTube Live Stream requirements

  4 septembre 2023, par Aniol Pagès

  I'm trying to stream to YouTube using FFmpeg and DASH. I've generated the stream key and I'm successfully sending the generated files to YouTube. However, YouTube refuses the MPD manifest because it has two AdaptationSet (one for video and one for audio), and the documentation specifies that I should use only one for both video and audio

  


  I've tried to use the -adaptation_sets flag unsuccessfully, and also the -map flag.

  


  Here is one of the commands I've tried :
ffmpeg -re -i "/Users/user/Desktop/file.mp4" \        -map 0:v -map 0:a \        -use_template 1 -use_timeline 1 -window_size 5 -min_seg_duration 5000000 \        -f dash dash.mpd

  


  And with the -adaptation_sets flag :
ffmpeg -re -i "/Users/aniolpages/Desktop/2023-09-03 Taller colar filtrar assubtilar.mp4" -map 0 -map 0 -c:a aac -c:v libx264 \ -use_timeline 1 -use_template 1 \ -window_size 5 -adaptation_sets "id=0,streams=v id=1,streams=a" \ -f dash dash.mpd

  


  Has someone been successful to conform the manifest to YouTube requirements ?

  


  Thank you very much !
