使用python 下载 mp4格式的腾讯视频

将腾讯视频本地化的方法

第一步查找视频的地址

视频的真实地址保存session中如上图

找到视频地址后，使用python下载腾讯视频

2.这里使用的解释器python3.5

需要安装request 和 moviepy

安装request

pip install requests

安装moviepy

pip install moviepy

安装ffmpeg

如果之前没安装过 ffmpeg , 这个时候导入 moviepy 开始使用会报错的, 所以我们可以先用 imageio 自带的方法下载 ffmpeg

新建install_ffmpeg.py,并执行

文本文件

import imageio
import ssl

# 下面这一句不是必须的, 但是某些情况下访问 https 会报SSL证书不受信任, 加上这一句可以允许通过
ssl._create_default_https_context = ssl._create_unverified_context

# 下载 ffmpeg 组件
imageio.plugins.ffmpeg.download()

　3.下载视频文件
