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，我可以一次下载一个视频。我不能一次下载多个视频。

目前，我的意思是

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')

结果为以下输出

>> Download is complete

并且YouTube文件已下载。当我尝试使用播放列表链接（示例）进行下载时，只会下载第一个视频。没有输出错误。

我希望能够下载整个播放列表，而无需重新提示用户。

Answer 1

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，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仅下载音轨，则必须修改 Youtube 标签常量的值。空的 Playlist.videos 列表修复取自此 Stackoverflow 帖子：PyTube3 播放列表返回空列表

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 2

如果需要下载播放列表中每一项的最高质量视频

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 3

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 4

您可以导入Playlist以实现此目的。在redoc中没有引用播放列表，尽管GitHub存储库中有一部分可在此处找到。脚本的源代码在此处的仓库中。

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：我发现该支持方法Playlist.video_urls无效。这些视频仍在下载中，如此处所示

Answer 5

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，而不是 pytube。

现在Playlist.video_urls效果很好。

并且Playlist.populate_video_urls()该功能已被弃用。
