我想在这样的程序中使用格式数字

import youtube_dl

url = "https://www.youtube.com/watch?v=BaW_jenozKc"
ydl_opts = {
    'verbose': True,
    'format': 'bestaudio/best', #maybe like this 'formatid'= 22
    'outtmpl': '%(title)s-%(id)s.%(ext)s',
    'noplaylist': True,
}
with youtube_dl.YoutubeDL(ydl_opts) as ydl:
    ydl.download([url])

我该怎么做

Answer 1

如果你真的想要格式22，那么确实，传入一个22的format键。如果 22 不可用，您可以使用 /best 回退到最佳视频格式：

ydl_opts = {
    'format': '22/best',
    ...
