可以"轻松加密和解密视频.您遇到的问题是播放器是一个黑匣子，您需要编写自己的DirectX过滤器来进行解密，并要求人们使用它来观看您的视频.

如果您要视频来告诉您如何加密和解密数据，我建议您如果不能阅读，就永远不能成为程序员.网络上有大量的文章供您选择.

如果您不是这两个意思中的任何一个，那么如果您需要我们的帮助，请尝试弄清楚.

You can''t easily encrypt and decrypt videos. The issue you have is that the players are a black box, you''d need to write your own DirectX filter that does the decrypting and require that people use it to watch your videos.

If you''re asking for videos to tell you how to encrypt and decrypt data, I''d suggest you can never be a programmer if you can''t read. There''s tons of articles on the web for you.

If you don''t mean either of those two things, then try making sense if you want help from us.
