Download Youtube video to mp3 with Python

#python #showdev #tutorial #productivity

I often need to download videos from Youtube in mp3 format. There are many websites where you can convert Youtube videos to mp3, but I am giving you a simple Python script that does the same job.

I am using youtube_dl. Command-line program to download videos from YouTube.com and other video sites. It requires the Python interpreter, version 2.6, 2.7, or 3.2+, and it is not platform-specific. It should work on your Unix box, on Windows, or on macOS.

Let's jump to the code:

import youtube_dl
def run():
    video_url = input("please enter youtube video url:")
    video_info = youtube_dl.YoutubeDL().extract_info(
        url = video_url,download=False
    )
    filename = f"{video_info['title']}.mp3"
    options={
        'format':'bestaudio/best',
        'keepvideo':False,
        'outtmpl':filename,
    }

    with youtube_dl.YoutubeDL(options) as ydl:
        ydl.download([video_info['webpage_url']])

    print("Download complete... {}".format(filename))

if __name__=='__main__':
    run()

Just enter the URL of the song and the script will download that song in mp3 format, cool isn't it?

Thank you all.

`from pytube import YouTube

total_size = stream.filesize
bytes_downloaded = total_size - bytes_remaining
percentage_of_completion = bytes_downloaded / total_size * 100
print(f"Descărcare: {percentage_of_completion:.2f}% completă.")

Here is a python script through which you can download all the videos in a playlist in .mp3 format

import re
import os
from pytube import Playlist
from pytube import YouTube
from pathlib import Path

YOUTUBE_STREAM_AUDIO = '320' # modify the value to download a different stream
DOWNLOAD_DIR = "./" # directory where you want to store the songs 
AUDIO_DIR = os.path.join(DOWNLOAD_DIR, 'audio')

p = input('Enter the playlist URL(make sure it is a public playlist): ')
playlist = Playlist(p)

# this fixes the empty playlist.videos list
playlist._video_regex = re.compile(r"\"url\":\"(/watch\?v=[\w-]*)")

print(len(playlist.video_urls))

for url in playlist.video_urls:
    yt = YouTube(url)

    video = yt.streams.filter(abr=YOUTUBE_STREAM_AUDIO ).last()
    out_file = video.download(output_path=DOWNLOAD_DIR)
    base, ext = os.path.splitext(out_file)
    new_file = Path(f'{base}.mp3')
    os.rename(out_file, new_file)
    if new_file.exists():
        print(f'{yt.title} has been successfully downloaded.')
    else:
        print(f'ERROR: {yt.title}could not be downloaded!')

thaks for the post!
i had some problems with the code and i extended it to be able to download single songs and playlists. (sorry for the bad english not nativ)

import youtube_dl

def main():
    link = input("give link: ")
    output = "C:/something/somethin" # example path

    prepLink(link, output)


def downloadVideo(videoInfo ,path):
    try:
        filename = f"{path}/{videoInfo['title']}.mp3"
        options={
            'format':'bestaudio/best',
            'keepvideo':False,
            'outtmpl': filename,
        }
        print(f"[script] downloading {videoInfo['title']}")

        with youtube_dl.YoutubeDL(options) as ydl:
            ydl.download([videoInfo['webpage_url']])
    except:
        print("error occured with one video")

def prepLink(link, path):
    video_url = link
    video_info = youtube_dl.YoutubeDL().extract_info(
        url = video_url,download=False
    )

    try: 
        # trying it for a playlist
        for singleVideoInfo in video_info['entries']:
            downloadVideo(singleVideoInfo, path)
    except KeyError:
        # if the KeyError is raised it will be a  KeyError: 'entries'
        # it is a single video
        downloadVideo(video_info, path)
    print("download complete")

if __name__=='__main__':
    main()

comment for simplification.
You can now also choose the output!

Here is also the code to download mp3 from youtube in highest possible quality using pytube:

from pytube import YouTube
import os
from pathlib import Path


def youtube2mp3 (url,outdir):
    # url input from user
    yt = YouTube(url)

    ##@ Extract audio with 160kbps quality from video
    video = yt.streams.filter(abr='160kbps').last()

    ##@ Downloadthe file
    out_file = video.download(output_path=outdir)
    base, ext = os.path.splitext(out_file)
    new_file = Path(f'{base}.mp3')
    os.rename(out_file, new_file)
    ##@ Check success of download
    if new_file.exists():
        print(f'{yt.title} has been successfully downloaded.')
    else:
        print(f'ERROR: {yt.title}could not be downloaded!')

But it I can't edit the mp3 tags of the file download with it. Can anyone tell me what happand?

Rowe Morehouse • May 24 '21

why not pytube?

pypi.org/project/pytube/

or pytube3, pytubeX

I used the pytube but I don't know how to download files as mp3, I did download the audio only but the format was mp4.
that's why I am trying this library as I found an explanation how to do it.
