问题
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/watch?v=WH7xsW5Os10")
vids= yt.streams.all()
for i in range(len(vids)):
print(i,'. ',vids[i])
vnum = int(input("Enter vid num: "))
vids[vnum].download(r"C:\YTDownloads")
print('done')
I managed to download the 'audio' version, but it was in .mp4
format. I did try to rename the extension to .mp3
, and the audio played, but the application (Windows Media Player) stopped responding and it began to lag.
How can I download the video as an audio file, in .mp3
format directly? Please provide some code as I am new to working with this module.

I'm afraid you can't. The only files available for direct download are the ones which are listed under yt.streams.all()
.
However, it is straightforward to convert the downloaded audio file from .mp4
to .mp3
format. For example, if you have ffmpeg installed, running this command from the terminal will do the trick (assuming you're in the download directory):
$ ffmpeg -i downloaded_filename.mp4 new_filename.mp3
Alternatively, you can use Python's subprocess
module to execute the ffmpeg command programmatically:
import os
import subprocess
import pytube
yt = pytube.YouTube("https://www.youtube.com/watch?v=WH7xsW5Os10")
vids= yt.streams.all()
for i in range(len(vids)):
print(i,'. ',vids[i])
vnum = int(input("Enter vid num: "))
parent_dir = r"C:\YTDownloads"
vids[vnum].download(parent_dir)
new_filename = input("Enter filename (including extension): ")) # e.g. new_filename.mp3
default_filename = vids[vnum].default_filename # get default name using pytube API
subprocess.run([
'ffmpeg',
'-i', os.path.join(parent_dir, default_filename),
os.path.join(parent_dir, new_filename)
])
print('done')
EDIT: Removed mention of subprocess.call
. Use subprocess.run
(unless you're using Python 3.4 or below)

I am assuming you are using Python 3 and pytube 9.x, you can use the filter method to "filter", the file extension you are interested in.
For example, if you would like to download mp4 video file format it would look like the following:
pytube.Youtube('url here').streams.filter(file_extension='mp4').first()
if you would like to pull audio it would look like the following:
pytube.Youtube('url here').streams.filter(only_audio=True).all()
Hope that helps anyone landing on this page; rather than converting unnecessarily.

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')

here is a mildly more slim and dense format for downloading an mp4 video and converting from mp4 to mp3:
Download will download the file to the current directory or location of the program, this will also convert the file to mp3 as a NEW file.
from pytube import YouTube
import os
import subprocess
import time
while True:
url = input("URL: ")
# Title and Time
print("...")
print(((YouTube(url)).title), "//", (int(var1)/60),"mins")
print("...")
# Filename specification
# Prevents any errors during conversion due to illegal characters in name
_filename = input("Filename: ")
# Downloading
print("Downloading....")
YouTube(url).streams.first().download(filename=_filename)
time.sleep(1)
# Converting
mp4 = "'%s'.mp4" % _filename
mp3 = "'%s'.mp3" % _filename
ffmpeg = ('ffmpeg -i %s ' % mp4 + mp3)
subprocess.call(ffmpeg, shell=True)
# Completion
print("\nCOMPLETE\n")
This is an infinite loop that will allow the renaming, download, and conversion of multiple URLs.

You will need to install pytubemp3 (using pip install pytubemp3
) latest version 0.3 + then
from pytubemp3 import YouTube
YouTube(video_url).streams.filter(only_audio=True).first().download()
