python将下载到本地m3u8视频合成MP4的代码详解

代码如下所示：

import osimport requestsimport datetimefrom Crypto.Cipher import AESdef decode_key_file(key_file_name): with open(key_file_name,'r') as f: data=f.read() return datadef 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')

视频下载下来如下图所示

https://ngmov.me/?channelCode=ngdl50这个应用下载下来的视频就是这样的解法

改进版本

def decode_key_file(key_file_name): with open(key_file_name, 'r') as f: data = f.read() return datadef 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) try: key = decode_key_file(data_list[1][0]) except: key = one_file_name 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))else: with open(key + '.mp4', ’ab’) as f: f.write(data_name) f.flush()if __name__ == ’__main__’: data_list = os.listdir('/home/dfy/Videos/Download') index=0 for path_one in data_list: index+=1 if index<18: continue decode_video('/home/dfy/Videos/Download' + '/' + path_one)
