使用 Pytube 从 YouTube 下载播放列表

Question

我希望使用 PyTube 库下载 YouTube 播放列表。目前，我可以一次下载一个视频。我一次不能下载多个视频。

目前，我的建议是

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')

这会产生以下输出

>> Download is complete

YouTube 文件已下载。当我尝试使用播放列表链接 (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 来实现这一点。尽管GitHub repo found here 中有一个部分，但重做中没有对播放列表的引用。脚本的来源在 repo here。

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

上述解决方案不再有效。这是一个下载 Youtube 播放列表中引用的视频的声音流的代码。使用的是 Pytube3，而不是 pytube。请注意，播放列表必须是公开的，下载才能成功。此外，如果您想下载完整视频而不是只下载音轨，则必须修改 Youtube 标签常量的值。空的 Playlist.videos 列表修复取自 Stackoverflow 帖子：PyTube3 Playlist returns empty list

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)

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()

我使用的是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。

此代码允许您将播放列表下载到您指定的文件夹

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 5

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 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，它可以帮助您将播放列表专门下载为 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
