我一直在使用pytube在Python中下载YouTube视频。到目前为止，我已经能够以MP4格式下载。
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')
我设法下载了"音频"版本，但它以.mp4格式。我确实尝试将扩展名重命名为.mp3，并且播放了音频，但是应用程序（Windows Media Player）停止响应，并且开始滞后。
如何以.mp3格式直接下载视频作为音频文件？请提供一些代码，因为我是使用此模块的新手。
如何将视频作为音频文件下载，以.mp3格式直接？
我恐怕你不能。唯一可直接下载的文件是在yt.streams.all()中列出的文件。
但是，将下载的音频文件从.mp4转换为.mp3格式很简单。例如，如果您已安装了FFMPEG，则从终端运行此命令将有效（假设您在下载目录中）：
$ ffmpeg -i downloaded_filename.mp4 new_filename.mp3
另外，您可以使用Python的subprocess模块来编程执行FFMPEG命令：
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')
编辑：删除提及subprocess.call。使用subprocess.run（除非您使用Python 3.4或以下）
我假设您正在使用Python 3和 pytube 9.x ，您可以将过滤器方法使用" filter＆quot"，您感兴趣的文件扩展程序in。
例如，如果您想下载MP4视频文件格式，则看起来如下：
pytube.YouTube("url here").streams.filter(file_extension="mp4").first()
如果您想拉音频，则看起来如下：
pytube.YouTube("url here").streams.filter(only_audio=True).all()
希望可以帮助任何人降落在此页面上；而不是不必要地转换。
您需要安装Pytubemp3（使用pip install pytubemp3）最新版本0.3 然后
from pytubemp3 import YouTube
YouTube(video_url).streams.filter(only_audio=True).first().download()
将视频作为音频下载，然后将音频扩展更改为mp3：
from pytube import YouTube
import os
url = str(input("url:- "))
yt = YouTube(url)
video = yt.streams.filter(only_audio=True).first()
downloaded_file = video.download()
base, ext = os.path.splitext(downloaded_file)
new_file = base + '.mp3'
os.rename(downloaded_file, new_file)
print("Done")
pytube不支持" mp3"格式，但您可以以WebM格式下载音频。以下代码证明了它。
from pytube import YouTube
yt = YouTube("https://www.youtube.com/watch?v=kn8ZuOCn6r0")
stream = yt.streams.get_by_itag(251)
ITAG是独特的ID
stream.download()
对于mp3，您必须将（MP4或WebM）文件格式转换为mp3。
使用此代码，您将从播放列表中下载所有视频，并从MP4和MP4音频格式中保存标题。
我在这个问题中使用了@scrpy的代码，以及 @jean-pierre schnyder的提示从这个答案
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')
这是一种略微苗条和密集的格式，用于下载MP4视频并从MP4转换为MP3：
下载将将文件下载到程序的当前目录或位置，这也将将文件转换为mp3作为新文件。
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("nCOMPLETEn")
这是一个无限循环，将允许重命名，下载和转换多个URL。
from pytube import YouTube
yt = YouTube(url)
yt.streams.get_audio_only().download(output_path='/home/',filename=yt.title)
pytube不支持" mp3"格式，但您可以以WebM格式下载音频。以下代码证明了它。
from pytube import YouTube
yt = YouTube("https://www.youtube.com/watch?v=kn8ZuOCn6r0")
stream = yt.streams.get_by_itag(251)
stream.download()
对于mp3，您必须将（MP4或WebM）文件格式转换为mp3。
这是我的解决方案：
import os
import sys
from pytube import YouTube
from pytube.cli import on_progress
PATH_SAVE = "D:Downloads"
yt = YouTube("YOUR_URL", on_progress_callback=on_progress)
#Download mp3
audio_file = yt.streams.filter(only_audio=True).first().download(PATH_SAVE)
base, ext = os.path.splitext(audio_file)
new_file = base + '.mp3'
os.rename(audio_file, new_file)
#Download Video
ys = yt.streams.filter(res="1080p").first()
ys.download(PATH_SAVE)
工作：Python v3.9.x和Pytube V11.0.1
尝试使用：
from pytube import YouTube
import os
link = input('enter the link: ')
path = "D:\" #enter the path where you want to save your video
video = YouTube(link)
print( "title is : ", video.title)
#download video
print("title is : ", video.title)
video.streams.filter(only_audio=True).first().download( path , filename ="TemporaryName.Mp4" )
#remove caracters (" | , / ..... ) from video title
VideoTitle = video.title
VideoTitle = VideoTitle.replace('"' , " ")
VideoTitle = VideoTitle.replace('|', " ")
VideoTitle = VideoTitle.replace(',', " ")
VideoTitle = VideoTitle.replace('/"' , " ")
VideoTitle = VideoTitle.replace('\', " ")
VideoTitle = VideoTitle.replace(':', " ")
VideoTitle = VideoTitle.replace('*"' , " ")
VideoTitle = VideoTitle.replace('?', " ")
VideoTitle = VideoTitle.replace('<', " ")
VideoTitle = VideoTitle.replace('>"' , " ")
#change name and converting Mp4 to Mp3
my_file = path + "\" + "TemporaryName.mp4"
base = path + "\" + VideoTitle
print("New Video Title is :" +VideoTitle)
os.rename(my_file, base + '.mp3')
print(video.title, ' nhas been successfully downloaded as MP3')
这是我的解决方案：
from os import path, rename
from pytube import YouTube as yt
formato = ""
descarga = desktop = path.expanduser("~/Desktop")
link = input("Inserte el enlace del video: ")
youtube = yt(link)
while formato != "mp3" and formato != "mp4":
formato = input("¿Será en formato mp3 o mp4? ")
if formato == "mp4":
youtube.streams.get_highest_resolution().download(descarga)
elif formato == "mp3":
video = youtube.streams.first()
downloaded_file = video.download(descarga)
base, ext = path.splitext(downloaded_file)
new_file = base + '.mp3'
rename(downloaded_file, new_file)
print("Descarga completa!")
input("Presiona Enter para salir...")
这是我的解决方案。只需使用Pytube的文件名选项重命名下载内容的名称。
url = input("URL of the video that will be downloaded as MP^: ")
try:
video = yt(url)
baslik = video.title
print(f"Title: {baslik}")
loc = input("Location: ")
print(f"Getting ITAG info for {baslik}")
for itag in video.streams.filter(only_audio=True): # It'll show only audio streams.
print(itag)
itag = input("ITAG secimi: ")
print(f"{baslik} sesi {loc} konumuna indiriliyor.")
video.streams.get_by_itag(itag).download(loc, filename=baslik + ".mp3") # And you can rename video by filename= option. Just add .mp3 extension to video's title.
print("Download finished.")
except:
print("Enter a valid URL")
sys.exit()
这对我来说很好：
pip install pytube
pip install os_sys
# importing packages
from pytube import YouTube
import os
# url input from user
yt = YouTube(
str(input("paste your link")))
# extract only audio
video = yt.streams.filter(only_audio=True).first()
# check for destination to save file
print("Enter the destination (leave blank for current directory)")
destination = str(input(">> ")) or '.'
# download the file
out_file = video.download(output_path=destination)
# save the file
base, ext = os.path.splitext(out_file)
new_file = base + '.mp3'
os.rename(out_file, new_file)
# result of success
print(yt.title + " has been successfully downloaded.")
这是使用Pytube下载最高质量音乐的功能，并将其保存在所需目录中。
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!')
我有一种使用Pytube的MP3下载YouTube视频的更多Pythonic方法：
# Use PyTube to download a YouTube video, then convert to MP3 (if needed) using MoviePy
import pytube
from moviepy.editor import AudioFileClip
link = "your youtube link here"
fn = "myfilename.mp3"
yt = pytube.YouTube(str(link))
video = yt.streams.filter(only_audio=True).first()
out_file = video.download(output_path='.')
os.rename(out_file, fn)
# Check is the file a MP3 file or not
if not out_file.endswith('.mp3'):
# File is not a MP3 file, then try to convert it (first rename it)
dlfn = '.'.join(fn.split('.')[:-1]) + '.' + out_file.split('.')[-1]
os.rename(fn, dlfn)
f = AudioFileClip(dlfn)
f.write_audiofile(fn)
f.close()
os.remove(dlfn)
代码写在python3中。确保安装库： python3 -m pip install pytube moviepyhightpy不支持每个音频文件，但它支持大多数："空"MP4（仅具有音乐的MP4），wav等...
为什么转换为mp3很重要？许多人只是重命名文件，但是此不能转换文件！如果您使用vlc使用vlc，则VLC将播放文件不是作为MP3，而是作为原始格式播放。因此，如果您使用仅支持MP3的软件播放文件，则音频播放器将返回错误。
