Download video in mp3 format using pytube

Question

I have been using pytube to download youtube videos in python. So far I have been able to download in mp4 format.

yt = pytube.YouTube(\"https://www.youtube.com/         


        

Answer 1

With this code you will download all the videos from a playlist and saving them with the title from youtube in mp4 and mp4 audio formats.

i used the code from @scrpy in this question and the hint from @Jean-Pierre Schnyder from this answer

import os
import subprocess
import re
from pytube import YouTube
from pytube import Playlist


path =r'DESTINATION_FOLER'
playlist_url = 'PLAYLIST_URL'

play = Playlist(playlist_url)

play._video_regex = re.compile(r"\"url\":\"(/watch\?v=[\w-]*)")
print(len(play.video_urls))
for url in play.video_urls:
    yt = YouTube(url)
    audio = yt.streams.get_audio_only()
    audio.download(path)
    nome = yt.title
    new_filename=nome+'.mp3'
    default_filename =nome+'.mp4'
    ffmpeg = ('ffmpeg -i ' % path default_filename + new_filename)
    subprocess.run(ffmpeg, shell=True)
         
    
print('Download Complete')
