使用 Pytube 从 YouTube 下载播放列表

Question

我想使用 PyTube 库下载 YouTube 播放列表。目前，我一次只能下载一个视频。我一次无法下载多个视频。

目前我的实现是

import pytube

link = input('Please enter a url link\n')
yt = pytube.YouTube(link)
stream = yt.streams.first()
finished = stream.download()
print('Download is complete')

这导致以下输出

>> Download is complete

YouTube 文件已下载。当我尝试使用播放列表 link (An example) 时，只会下载第一个视频。没有错误输出。

我希望能够在不重新提示用户的情况下下载整个播放列表。

Answer 1

您可以导入 Playlist 来实现此目的。尽管在 GitHub repo found here. The source of the script is in the repo here.

中有一个部分，但在 redoc 中没有对播放列表的引用

from pytube import Playlist

playlist = Playlist('https://www.youtube.com/watch?v=58PpYacL-VQ&list=UUd6MoB9NC6uYN2grvUNT-Zg')
print('Number of videos in playlist: %s' % len(playlist.video_urls))
playlist.download_all()

注意：我发现支持方法 Playlist.video_urls 不起作用。然而，视频仍在下载，as evidenced here

Answer 2

from pytube import Playlist
playlist = Playlist('https://www.youtube.com/playlist?list=PL6gx4Cwl9DGCkg2uj3PxUWhMDuTw3VKjM')
print('Number of videos in playlist: %s' % len(playlist.video_urls))
for video_url in playlist.video_urls:
    print(video_url)
playlist.download_all()

我正在使用 pytube3 9.6.4，不是 pytube。

现在 Playlist.video_urls 运行良好。

并且 Playlist.populate_video_urls() 函数已被弃用。

Answer 3

上述解决方案不再有效。这是下载 Youtube 播放列表中引用的视频的声音流的代码。使用的是 Pytube3，不是 pytube。请注意，播放列表必须为 public 才能下载成功。另外，如果你想下载完整的视频而不是只下载音轨，你必须修改 Youtube 标签常量的值。空 Playlist.videos 列表修复取自此 Whosebug post:

import re
from pytube import Playlist

YOUTUBE_STREAM_AUDIO = '140' # modify the value to download a different stream
DOWNLOAD_DIR = 'D:\Users\Jean-Pierre\Downloads'

playlist = Playlist('https://www.youtube.com/playlist?list=PLzwWSJNcZTMSW-v1x6MhHFKkwrGaEgQ-L')

# 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:
    print(url)

# physically downloading the audio track
for video in playlist.videos:
    audioStream = video.streams.get_by_itag(YOUTUBE_STREAM_AUDIO)
    audioStream.download(output_path=DOWNLOAD_DIR)

Answer 4

如果需要下载播放列表中每个项目的最高质量视频

playlist = Playlist('https://www.youtube.com/watch?v=VZclsCzhzt4&list=PLk-w4cD8sJ6N6ffzp5A4PQaD76RvdpHLP')

for video in playlist.videos:
    print('downloading : {} with url : {}'.format(video.title, video.watch_url))
    video.streams.\
        filter(type='video', progressive=True, file_extension='mp4').\
        order_by('resolution').\
        desc().\
        first().\
        download(cur_dir)

Answer 5

此代码允许您将播放列表下载到指定的文件夹

import re
from pytube import Playlist
playlist = Playlist('https://www.youtube.com/playlist?list=Pd5k1hvD2apA0DwI3XMiSDqp')   
DOWNLOAD_DIR = 'D:\Video'
playlist._video_regex = re.compile(r"\"url\":\"(/watch\?v=[\w-]*)")    
print(len(playlist.video_urls))    
for url in playlist.video_urls:
    print(url)    
for video in playlist.videos:
    print('downloading : {} with url : {}'.format(video.title, video.watch_url))
    video.streams.\
        filter(type='video', progressive=True, file_extension='mp4').\
        order_by('resolution').\
        desc().\
        first().\
        download(DOWNLOAD_DIR)

Answer 6

虽然这似乎是一个已解决的问题，但这是我的解决方案之一，可以帮助您下载播放列表，专门作为 1080P 30 FPS 或 720P 30 FPS 的视频（如果1080P 不可用).

from pytube import Playlist
playlist = Playlist('https://www.youtube.com/playlist?list=PLeo1K3hjS3uvCeTYTeyfe0-rN5r8zn9rw')
print('Number of videos in playlist: %s' % len(playlist.video_urls))

# Loop through all videos in the playlist and download them
for video in playlist.videos:
    try:
        print(video.streams.filter(file_extension='mp4'))
        stream = video.streams.get_by_itag(137) # 137 = 1080P30
        stream.download()
    except AttributeError:
        stream = video.streams.get_by_itag(22) # 22, 136 = 720P30; if 22 still don't work, try 136
        stream.download()
    except:
        print("Something went wrong.")

Answer 7

这对我有用。只需将播放列表中的网址一一下载即可：

from pytube import Playlist

playlist = Playlist('URL')
print('Number of videos in playlist: %s' % len(playlist.video_urls))
for video_url in playlist.video_urls:
    print(video_url)
    urls.append(video_url)
    for url in urls:
        my_video = YouTube(url)

        print("*****************DOWNLOAD VID*************")
        print(my_video.title)

        my_video = my_video.streams.get_highest_resolution()
        path = "PATH"
        my_video.download(path)
        print("VIDEO DOWNLOAD DONNNNE")

Answer 8

import pytube
from pytube import Playlist
playlist = Playlist('plylist link')
num = 0
for v in playlist.videos:
    print(v.watch_url)
    one = pytube.YouTube(v.watch_url)
    one_v = one.streams.get_highest_resolution()
    name = f"{0}" + one_v.default_filename
    one_v.download()
    num = num + 1

下载所有播放列表

Answer 9

这可以完美地下载完整的播放列表

检查 pytube github 安装

pip install pytube

现在，转到此文件夹并打开 cipher.py

D:\ProgramData\Anaconda3\Lib\site-packages\pytube\

在第 273 行替换

function_patterns = [
        r'a\.[a-zA-Z]\s*&&\s*\([a-z]\s*=\s*a\.get\("n"\)\)\s*&&\s*.*\|\|\s*(.*)\(',
        r'\([a-z]\s*=\s*([a-zA-Z0-9$]{3})(\[\d+\])?\([a-z]\)',
    ]

main.py

from pytube import Playlist
playlist = Playlist('https://www.youtube.com/playlist?list=PLwdnzlV3ogoXUifhvYB65lLJCZ74o_fAk')

playlist._video_regex = re.compile(r"\"url\":\"(/watch\?v=[\w-]*)")

print(len(playlist.video_urls))

for url in playlist.video_urls:
    print(url)

for video in playlist.videos:
    video.streams.get_highest_resolution().download()
