有两种方法可以实现目标

There are two ways through which you can achieve your goal

要播放该文件时，请下载文件并对其进行加密，然后将其解密以将其存储在临时文件中并进行播放.

Download a file and encrypt it, when you want to play that file decry-pt it in a temporary file and play it.

如果您想动态播放加密文件(而不是在临时文件中解密)，则可以使用 Libmedia 库.它将加密的文件流式传输到本地主机上，然后从本地主机上播放

if you want to play encrypted file on the fly (not decrypting it in a temp file) then you can use Libmedia library. It streams encrypted file on local host and play it from there
