我安装了 pytube 来从一些 YouTube 视频中提取字幕。下面的代码都给出了 xml 标题。
from pytube import YouTube
yt = YouTube('https://www.youtube.com/watch?v=4ZQQofkz9eE')
caption = yt.captions['a.en']
print(caption.xml_captions)
正如文档中提到的
yt = YouTube('http://youtube.com/watch?v=2lAe1cqCOXo')
caption = yt.captions.get_by_language_code('en')
caption.xml_captions
但在这两种情况下，我都会得到 xml 输出，并且在使用时
print(caption.generate_srt_captions())
我收到如下错误。你能帮忙看看如何提取srt格式吗？
