以此视频为例玩法一直被误解，但数值碾压五虎的存在！！_哔哩哔哩bilibili_英雄联盟_第一视角

b站视频网址经过更新已变成了这种形式，由这三个BV_id,spm_id_from,vd_source参数构成

1.导入相关包

2.写入headers，里面要加cookie（获取最高清画质），referer,请求头

3.向上面的url发送请求,获取视频标题，

这里利用正则提取标题数据

4.获取视频和音频的链接

也是用正则提取相关的视频和音频链接

5.保存视频和音频的数据

6.音视频合成（用到ffmpeg软件）

这里得去安装ffmpeg和配置相关环境变量(网上有相关教程)，配置完后一定要重启电脑,否则无法生效.

7.主函数

源码：

import requests
import re
import os
import json
import subprocess
if not os.path.exists('./b_video'):
    os.mkdir('./b_video')
headers = {
    #获取最高清1080p数据,加入cookie个人信息
