python将下载到本地m3u8视频合成MP4的代码详解
(编辑：jimmy 日期: 2024/11/18 浏览：3 次 )
代码如下所示：
import os
import requests
import datetime
from Crypto.Cipher import AES
def decode_key_file(key_file_name):
with open(key_file_name,"r") as f:
data=f.read()
return data
def decode_m_file(m_file_name):
with open(m_file_name,"r") as f:
data=f.read()
return data.split("\n")[6::2]
def decode_video(filename):
data_list=[[],[],[]]
file_list=os.listdir(filename)
for one_file_name in file_list:
if "m3u8" in one_file_name:
data_list[0].append(filename+"/"+one_file_name)
elif "key" in one_file_name:
data_list[1].append(filename + "/" + one_file_name)
else:
data_list[2].append(filename + "/" + one_file_name)
key=decode_key_file(data_list[1][0])
name_list=decode_m_file(data_list[0][0])
for one_name in name_list:
for path_name in data_list[2]:
if one_name in path_name:
with open(path_name,"rb") as f:
data_name=f.read()
if len(key): # AES 解密
cryptor = AES.new(key, AES.MODE_CBC, key)
with open(key + ".mp4", 'ab') as f:
f.write(cryptor.decrypt(data_name))
if __name__ == '__main__':
decode_video("./data")
