用于下载YouTube视频的Python3库。

感谢赞助商：

安装

pip install pytubefix

快速开始

下载最高分辨率的mp4视频：

from pytubefix import YouTube
from pytubefix.cli import on_progress
 
url = "url"
 
yt = YouTube(url, on_progress_callback = on_progress)
print(yt.title)
 
ys = yt.streams.get_highest_resolution()
ys.download()

如果你想保存为.mp3格式，只需传递mp3=True参数（MPEG-4 AAC音频编解码器）：

from pytubefix import YouTube
from pytubefix.cli import on_progress
 
url = "url"
 
yt = YouTube(url, on_progress_callback = on_progress)
print(yt.title)
 
ys = yt.streams.get_audio_only()
ys.download(mp3=True)

如果你想下载完整播放列表：

from pytubefix import Playlist
from pytubefix.cli import on_progress
 
url = "url"

pl = Playlist(url)

for video in pl.videos:
    ys = video.streams.get_audio_only()
    ys.download(mp3=True)

如果你想添加认证

from pytubefix import YouTube
from pytubefix.cli import on_progress
 
url = "url"

yt = YouTube(url, use_oauth=True, allow_oauth_cache=True, on_progress_callback = on_progress)
           
ys = yt.streams.get_highest_resolution()

ys.download() # 你只会在下载时收到一次认证请求

字幕/说明文字轨道：

查看可用字幕：

from pytubefix import YouTube

yt = YouTube('http://youtube.com/watch?v=2lAe1cqCOXo')
subtitles = yt.captions

print(subtitles)

打印字幕轨道：

from pytubefix import YouTube
 
yt = YouTube('http://youtube.com/watch?v=2lAe1cqCOXo')

caption = yt.captions.get_by_language_code('en')
print(caption.generate_srt_captions())

现在你可以将字幕保存到txt文件中：

from pytubefix import YouTube
 
yt = YouTube('http://youtube.com/watch?v=2lAe1cqCOXo')

caption = yt.captions.get_by_language_code('en')
caption.save_captions("captions.txt")

使用频道：

获取频道名称：

from pytubefix import Channel

c = Channel("https://www.youtube.com/@ProgrammingKnowledge/featured")

print(f'频道名称: {c.channel_name}')

下载频道中的所有视频：

from pytubefix import Channel

c = Channel("https://www.youtube.com/@ProgrammingKnowledge")

print(f'正在下载来自以下频道的视频: {c.channel_name}')

for video in c.videos:
    download = video.streams.get_highest_resolution().download()

搜索：

>>> from pytubefix import Search
>>> 
>>> results = Search('Github Issue Best Practices')
>>> 
>>> for video in results.videos:
...     print(f'标题: {video.title}')
...     print(f'URL: {video.watch_url}')
...     print(f'时长: {video.length} 秒')
...     print('---')
