2024最新python使用yt-dlp

1.获取yt的cookie

1）google浏览器下载Get cookies.txt LOCALLY插件

https://chromewebstore.google.com/detail/get-cookiestxt-locally/cclelndahbckbenkjhflpdbgdldlbecc

2）导出cookie

推荐使用cookies方式，因为：
更安全，不需要存储密码
避免频繁登录导致的验证码问题
可以访问账号订阅的内容
支持年龄限制视频的下载
记住要定期更新cookies以确保其有效性。

2.yt-dlp下载yt-dlp的GitHub地址

1）使用Pycharm(2024.3)进行代码demo编写

2）使用的python版本3.9.13

3）Pycharm下载对应的第三方库yt-dlp

4）使用命令进行下载

pip install yt-dlp

提示pip警告
[notice] A new release of pip is available: 23.2.1 -> 24.3.1
[notice] To update, run: python.exe -m pip install --upgrade pip

更新就行了
python.exe -m pip install --upgrade pip

5）复制cookie到根目录

5）python代码

import yt_dlp
from pathlib import Path
import os


def yt_test(url):
    try:
        # 创建下载目录
        video_path = Path("downloads/video")
        audio_path = Path("downloads/audio")
        video_path.mkdir(parents=True, exist_ok=True)
        audio_path.mkdir(parents=True, exist_ok=True)

        # yt-dlp 基础配置
        common_opts = {

            'nocheckcertificate': True,
            'prefer_insecure': True
        }

        print("开始下载视频...")
        print(f"使用cookies文件: {common_opts['cookiefile']}")

        # 视频下载选项

            'outtmpl': str(video_path / '%(title)s.%(ext)s'),
        }

            print(f"视频标题: {title}")
            print(f"视频时长: {duration // 60}:{duration % 60:02d}")
            print(f"缩略图URL: {thumbnail}")

        # 下载视频
        print("\n开始下载视频文件...")
        with yt_dlp.YoutubeDL(video_opts) as ydl:
            ydl.download([url])

        # 下载音频
        print("\n开始下载音频文件...")
        with yt_dlp.YoutubeDL(audio_opts) as ydl:
            ydl.download([url])

        # 获取下载后的文件路径
        video_file = next(video_path.glob(f"{title}.*"))
        audio_file = next(audio_path.glob(f"{title}.*"))

        print("\n下载完成!")
        print(f"视频文件: {video_file}")
        print(f"音频文件: {audio_file}")

        return {
            "status": "success",

            "video_path": str(video_file),
            "audio_path": str(audio_file)
        }

    except Exception as e:
        print(f"\n下载过程中出错: {str(e)}")
        return {"status": "error", "message": str(e)}


if __name__ == "__main__":
    # 测试URL
    test_url = "******.com/watch?v=_KFzaJSxBcY"

    print("测试")
    print("-" * 50)
    print(f"测试URL: {test_url}")
    print("-" * 50)

    result = yt_test(test_url)

    if result["status"] == "success":
        print("\n测试成功!")
        print("-" * 50)
        print(f"标题: {result['title']}")

    else:
        print("\n测试失败!")
        print("-" * 50)
        print(f"错误信息: {result['message']}")

6）运行测试

3.注意事项

1）配置

猫: 常用7890
V2: 常用 10808/10809
S: 常用1080

2）yt-dlp配置

common_opts = {
‘cookiefile’: r’cookies.txt’,
‘quiet’: False,
‘no_warnings’: False,
‘verbose’: True,
#和上方的端口进行对应
‘proxy’: ‘http://127.0.0.1:10809’,
‘socket_timeout’: 30,
‘retries’: 3,
‘nocheckcertificate’: True,
‘prefer_insecure’: True
}
