• 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 programatically set the export date to download date using python

  16 janvier 2021, par Vladimir Tarasov

  i'm currently using the code below to export a youtube-dl converted video (with ffmpeg and youtube-dl for python)
how could i programatically set the good options for ffmpeg to add the download date (at least today's date) to the .mp3 file ?

  


  ydl_opts = {
    'format': 'bestaudio/best',
    'outtmpl': path + urlToTitleYT(link) + '.mp3',
    'postprocessors': [{
        'key': 'FFmpegExtractAudio',
        'preferredcodec': 'mp3',
        'preferredquality': '320',
    }],
}

with youtube_dl.YoutubeDL(ydl_opts) as ydl:
    ydl.download([link])
