Widevine CENC在Azure媒体服务上的加密设置 [英] Encryption settings for Widevine CENC on Azure Media Services
问题描述
我想使用Azure媒体服务来提供用于内容保护的许可证.我使用PHP SDK创建了ContentKey，并获得了Widevine的许可证URL.我在一边使用打包器来对视频进行加密.
I want to use Azure Media Services to provide the licenses for content protection. I created the ContentKey using the PHP SDK, and got the license URL for Widevine. I'm using packager in my side to encrypt the video.
我的问题是(主要是由于无知)，我不知道在哪里可以找到参数"--signer"，-aes_signing_key"和"--aes_signing_iv"的值.我在一些教程中读到这些值是由Widevine提供的，但就我而言，我假设这些值是由Azure提供的.
My problem is (mostly because of ignorance) that I don't know where to find the value for the parameters "--signer", "--aes_signing_key" and "--aes_signing_iv". I read in some tutorials that these values are provided by Widevine, but in my case I assumed that were provided by Azure.
PHP或 packager 都不是问题.即使使用REST API，我也不知道哪些信息与签名者"，签名密钥"和签名iv"相关.即使其他平台，例如 bitcodin 和其他打包程序，也需要此信息.
It's not an issue with PHP or packager. Even using the REST API I don't know which information correlates to "signer" "signing key" and "signing iv". This information is required even by other platforms like bitcodin and other packagers.
推荐答案
如果您使用自己的打包程序，则只需与我们一起配置通用加密密钥和Widevine许可模板，您将获得许可URL和KEY ID作为回报，您可以将这些价值放入打包机中.
If you are using your own packager, you only need to configure the common encryption key and Widevine License template with us, you will obtain a license URL and KEY ID as return, and you can put those value into your packager.
您不需要配置用于AES 128透明密钥加密的AES信封密钥.这是我们提供的另一项服务.
You don't need to configure AES envelope Key, which is for AES 128 clear key encryption. That's another service that we offer.
