我正在用Python 3制作一个小的图形界面，它应该下载一个带有URL的youtube视频.
import youtube_dl # Youtube_dl is used for download the video
ydl_opt = {"outtmpl" : "/videos/%(title)s.%(ext)s", "format": "bestaudio/best"} # Here we give some advanced settings. outtmpl is used to define the path of the video that we are going to download
def operation(link):
"""
Start the download operation
"""
try:
with youtube_dl.YoutubeDL(ydl_opt) as yd: # The method YoutubeDL() take one argument which is a dictionary for changing default settings
video = yd.download([link]) # Start the download
result.set("Your video has been downloaded !")
except Exception:
result.set("Sorry, we got an error.")
operation("https://youtube.com/watch?v=...")
当我执行代码时，会出现以下错误:
ERROR: YouTube said: Unable to extract video data
我看到了here，因为它找不到任何视频信息，我如何解决这个问题？
