python嗅探m3u8_python通过m3u8下载视频
python可以通过安装ffmpeg扩展来实现下载m3u8的视频，很多视频网站都提供m3u8
ffmpeg命令行格式如下
D:\Python36\Lib\site-packages\imageio_ffmpeg\binaries\ffmpeg-win64-v4.1.exe -i url -vcodec copy -acodec copy 视频.mp4
通过解析视频网站活动m3u8的url，再使用ffmeg可以实现视频下载
python代码如下：
# -*- coding:utf-8 -*-
import requests
from lxml import etree
# import ffmpeg
import imageio_ffmpeg
import subprocess
# url = 'https://jx.618g.com/?url=https://v.qq.com/x/cover/59l8gzmf4d9cjuu.html'
# response = requests.get(url)
# # print(response.text)
# # print(response.content)
# html_str = response.content
# html = etree.HTML(html_str)
# m3u8_url = html.xpath("//div[@class='player']/iframe/@src")[0].split('=')[-1]
# print(m3u8_url)
url = 'https://cn4.download05.com/hls/20190618/be22d970332fd4ba4d3c63b19ebd0667/1560840680/index.m3u8'
ffmpeg = imageio_ffmpeg.get_ffmpeg_exe()
cmd = ffmpeg + " -i " + url + " -vcodec copy -acodec copy 1.mp4"
print(cmd)
res = subprocess.call(cmd, shell=True)
