如何使用 Python 下载 YouTube 视频？

Question

我想用 Python 下载 YouTube 视频。我用Python试过opencv，但是一直有问题。我正在尝试使用 pytube3 和 Python 3。我尝试了这个程序（我在StackOverflow 上找到的）：

from pytube import YouTube
YouTube('http://youtube.com/watch?v=9bZkp7q19f0').streams.first().download()

但它因“HTTP 错误 410”错误而失败。当我运行各种 pytube 程序时，我不断收到“HTTP 错误 410”。我更改了 URL 并在浏览器中测试了 URL。当我运行 Python 程序下载视频时，没有任何效果。

我正在尝试运行此程序（正如我在此处找到的那样）：

from pytube import YouTube
 
try:
    yt_obj = YouTube('https://www.youtube.com/watch?v=DkU9WFj8sYo')
 
    print(f'Video Title is {yt_obj.title}')
    print(f'Video Length is {yt_obj.length} seconds')
    print(f'Video Description is {yt_obj.description}')
    print(f'Video Rating is {yt_obj.rating}')
    print(f'Video Views Count is {yt_obj.views}')
    print(f'Video Author is {yt_obj.author}')
 
except Exception as e:
    print(e)

我懂了：

在处理上述异常的过程中，又发生了一个异常：

回溯（最近一次调用最后一次）：文件“e.py”，第 14 行，在 raise Exception('Some exception occurred.') 异常：发生了一些异常。

我的研究表明 410 错误涉及一个 URL 被找到但随后被移动。由于问题发生在不同的 youtube 链接和不同的程序上，我不知所措。当我不断收到错误 410 消息时，如何下载 YouTube 视频？

Answer 1

有一个错误在pytube3的结果在410错误。有一个从该问题链接的修复程序似乎可以解决该问题。如果我安装补丁版本：

pip install git+https://github.com/Zeecka/pytube@fix_1060#egg=pytube

然后我可以获取有关 youtube 视频的信息而不会出现该错误：

>>> import pytube
>>> yt = pytube.YouTube('https://www.youtube.com/watch?v=DkU9WFj8sYo')
>>> yt.title
'Space Ranger Video Game using FXGL and JavaFX'

该修复已作为拉取请求提交。通读讨论，似乎仍有一些未解决的问题。
