视频下载

B站

B站视频下载，可以使用you-get和ffmpeg配合下载

一些老视频可以直接you-get音视频一起下载，但新视频大概率是图像和声音分离的，需要使用ffmpeg处理

2.Python脚本

一般4K视频需要有VIP会员，且登录； 即使是1080p，至少也要正式会员登录。

import subprocess

video_url = ""
download_cmd = f"you-get -o ./ {video_url}"
download_list_cmd = f"you-get -o ./ -l {video_url}"
download_cookie_cmd = f"you-get -o ./ {video_url}"

subprocess.run(download_cmd,shell=True)
