• 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);
}


  


• How to watch or download periscope live streams from start ?

  10 septembre 2019, par Sanchit

  I am trying to figure how watch/download a periscope livestream from it’s starting point. The app doesn’t let go back more than 2 minutes so I tried downloading as someone told me it downloads from beginning but it didn’t. It started from the current time.

  I tried running :

  youtube-dl https://www.pscp.tv/w/b_7KWDFyYVFaeFhCTXhaanp8MXluS09Sd05QRFZ4Uuj5klcOLvuiNqQPC2PcorcMlZOwD3uZyIP7o-UXVYNi

  I get

• Getting Error while trying to download youtube video by using python

  23 octobre 2024, par Aditya Kumar

  Code

  


  I'm working on a script that allows users to manually select and download separate video and audio streams from YouTube using yt-dlp. The script lists the available video and audio formats, lets the user choose their desired formats, and then merges them using FFmpeg.

  


  Here’s the complete code :

  


  import yt_dlp
import os
import subprocess

# Function to list and allow manual selection of video and audio formats
def download_and_merge_video_audio_with_selection(url, download_path):
    try:
        # Ensure the download path exists
        if not os.path.exists(download_path):
            os.makedirs(download_path)

        # Get available formats from yt-dlp
        ydl_opts = {'listformats': True}

        with yt_dlp.YoutubeDL(ydl_opts) as ydl:
            info_dict = ydl.extract_info(url, download=False)
            formats = info_dict.get('formats', [])

        # List available video formats (video only)
        print("\nAvailable video formats:")
        video_formats = [f for f in formats if f.get('vcodec') != 'none' and f.get('acodec') == 'none']
        for idx, f in enumerate(video_formats):
            resolution = f.get('height', 'unknown')
            filesize = f.get('filesize', 'unknown')
            print(f"{idx}: Format code: {f['format_id']}, Resolution: {resolution}p, Size: {filesize} bytes")

        # Let user select the desired video format
        video_idx = int(input("\nEnter the number corresponding to the video format you want to download: "))
        video_format_code = video_formats[video_idx]['format_id']

        # List available audio formats (audio only)
        print("\nAvailable audio formats:")
        audio_formats = [f for f in formats if f.get('acodec') != 'none' and f.get('vcodec') == 'none']
        for idx, f in enumerate(audio_formats):
            abr = f.get('abr', 'unknown')  # Audio bitrate
            filesize = f.get('filesize', 'unknown')
            print(f"{idx}: Format code: {f['format_id']}, Audio Bitrate: {abr} kbps, Size: {filesize} bytes")

        # Let user select the desired audio format
        audio_idx = int(input("\nEnter the number corresponding to the audio format you want to download: "))
        audio_format_code = audio_formats[audio_idx]['format_id']

        # Video download options (based on user choice)
        video_opts = {
            'format': video_format_code,  # Download user-selected video format
            'outtmpl': os.path.join(download_path, 'video.%(ext)s'),  # Save video as video.mp4
        }

        # Audio download options (based on user choice)
        audio_opts = {
            'format': audio_format_code,  # Download user-selected audio format
            'outtmpl': os.path.join(download_path, 'audio.%(ext)s'),  # Save audio as audio.m4a
        }

        # Download the selected video format
        print("\nDownloading selected video format...")
        with yt_dlp.YoutubeDL(video_opts) as ydl_video:
            ydl_video.download([url])

        # Download the selected audio format
        print("\nDownloading selected audio format...")
        with yt_dlp.YoutubeDL(audio_opts) as ydl_audio:
            ydl_audio.download([url])

        # Paths to the downloaded video and audio files
        video_file = os.path.join(download_path, 'video.webm')  # Assuming best video will be .mp4
        audio_file = os.path.join(download_path, 'audio.m4a')  # Assuming best audio will be .m4a
        output_file = os.path.join(download_path, 'final_output.mp4')  # Final merged file

        # FFmpeg command to merge audio and video
        ffmpeg_cmd = [
            'ffmpeg', '-i', video_file, '-i', audio_file, '-c', 'copy', output_file
        ]

        # Run FFmpeg to merge audio and video
        print("\nMerging video and audio...")
        subprocess.run(ffmpeg_cmd, check=True)

        print(f"\nDownload and merging complete! Output file: {output_file}")

    except Exception as e:
        print(f"An error occurred: {e}")

# Example usage
video_url = "https://www.youtube.com/watch?v=SOwk8FhfEZY"  # Replace with your desired video URL
download_path = 'C:/Users/vinod/Downloads/VideoDownload'  # Replace with your desired download path
download_and_merge_video_audio_with_selection(video_url, download_path)



  


  Explanation :

  


  The script first lists all available video formats (video-only) and audio formats (audio-only) from a given YouTube URL.

  


  It allows the user to manually select their preferred video and audio formats.

  


  After downloading the selected formats, it merges the video and audio streams into a single file using FFmpeg.

  


  Error

  


  while trying to run above mentioned code , I am getting this error :

  


  Merging video and audio...
An error occurred: [WinError 2] The system cannot find the file specified


  


  Requirements :

  


  


  yt-dlp : pip install yt-dlp

  


  


  


  FFmpeg : Make sure you have FFmpeg installed and added to your system's PATH.
