Encryption settings for Widevine CENC on Azure Media Services

由 喜你入骨 提交于 2020-04-11 06:32:32
问题 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. 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

Decrypting widevine DRM protected video in android using MediaDrm

问题 I am trying to decrypt widevine DRm protected media file using Android's MediaDrm API. But MediaDrm is instantiated using UUId( of DRM-scheme). Android developer site says "App accesses the DRM-scheme-identifying UUID, typically from metadata in the content, and uses this UUID to construct an instance of a MediaDrm object that is able to support the DRM scheme required by the content". (www.developer.android.com/reference/android/media/MediaDrm.html). So I tried to get UUID using

问题 I am trying to playback a wvm file that I download through an iOS app and located in the apps document directory. I am getting a 1013 error and I believe this is due to the files location and the WideVine api not having access to that location. Any ideas on how to overcome this? Or am I wrong and the issue is something else? Thanks 回答1: Well, I found this issue to be with the File URL starting with File:// Once I removed that it all worked great. 来源： https://stackoverflow.com/questions

Widevine video streaming on iOS and AirPlay

问题 Could you help us please with the following problem related to the DRM (Widevine) encrypted video stream playback and use of the AirPlay? When we tried to play the video from iPhone with use of the AirPlay on Apple TV, the "failed to load content” error was shown on the TV screen. We are not sure if that is correct behaviour. We think it is, because for encrypted video playback we cannot use the AirPlay as it transports the raw unencrypted stream, right? So far we found that the only possible
