如何将具有DRM许可证的mpeg破折号(MPD)转换为MP4? [英] How to convert mpeg dash (MPD) with DRM license to MP4?

问题描述

我正在尝试将其中具有DRM保护的MPD破折号文件转换为MP4文件.我确实有DRM许可证的URL.因此，我尝试使用ffmpeg库执行此操作，但是没有选择将许可证URL与ffmpeg命令一起传递以进行解密.

I am trying to convert a MPD dash file which has DRM protection in it to a MP4 file. I do have the URL to the DRM license. So, I tried to do this using ffmpeg library, but there is no option to pass the license URL along with ffmpeg command for decryption.

推荐答案

DRM旨在防止您这样做. DRM可以具有软件读取器或硬件读取器.硬件阅读器既不会提供解密密钥，也不会提供解密的内容.软件阅读器将尽可能以最混乱的方式进行操作.

DRM is designed and created to stop you from doing it. DRM can have software reader or hardware reader. Hardware reader will not give you neither decryption key, neither decrypted content. Software reader will do it in most obfuscated way possible.

因此ffm​​peg没有这种选择，因为从DRM的设计来看，这实际上是不可能的.

So ffmpeg does not have such option because it is virtually impossible by design of DRM.

但是，如果您与内容所有者有任何关系，他们可以共享您原始的加密密钥，并且您可以解密.

However, if you have any relations with content owner, they can share you original encryption key and you will be able to decrypt.
