yt-dlp "https://www.youtube.com/watch?v=dQw4w9WgXcQ"

import yt_dlp

with yt_dlp.YoutubeDL() as ydl:
    ydl.download([url])

# 下载到指定目录
yt-dlp -o "~/Downloads/%(title)s.%(ext)s" "URL"

# 自定义文件名格式
yt-dlp -o "%(uploader)s - %(title)s.%(ext)s" "URL"

import yt_dlp

    'outtmpl': '~/Downloads/%(title)s.%(ext)s',
}

with yt_dlp.YoutubeDL(ydl_opts) as ydl:
    ydl.download(["URL"])

# 打印视频信息（不下载）
yt-dlp --print filename "URL"

# 查看所有可用格式
yt-dlp -F "URL"

# 输出为 JSON
yt-dlp -j "URL"

import yt_dlp

ydl_opts = {
    'skip_download': True,  # 不下载，只提取信息
}

with yt_dlp.YoutubeDL(ydl_opts) as ydl:

    print(f"标题: {info['title']}")
    print(f"时长: {info['duration']}秒")
