推荐答案
只要你能解码它们，你可以用任何方式对它们进行编码......
As long as you can decode them, you can encode them just in any ways...
像Caesar密码一样简单的工作......或者你可以做更复杂的事情......
MP4文件只是位......所以你可以根据需要加密/解密它们......
Something as simple as the Caesar cipher will work... Or you can do more complicated stuff... An MP4 file is just bits... So you can crypt/decrypt them as you want...
