推荐答案

你没有一个简单的方法来做到这一点。为了使用内置播放器，数据必须是未加密的。



现在，这并不是说这是不可能的。你只需要写一个音频过滤器驱动程序 [ ^ ]（在C中）即时解密流。过滤器驱动程序将位于用于播放流的过滤器图形中。



哦，您还必须编写代码来将流加密到文件中。 />


这是一项琐碎任务的FAR，很难得到样本。

You don't have a simple method to do that. In order to use the built in player, the data has to be unencrypted.

Now, that's not to say it's impossible. You just have to write an audio filter driver[^] (in C) that decrypts the stream on-the-fly. The filter driver would sit in the filter graph used to play the stream.

Oh, and you also have to write code to encrypt the stream into a file.

This is FAR from a trivial task and samples are hard to come by.
