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'm currently using the Adobe RMSDK to read DRM EPUBs. It renders an EPUB page as an image, and sends it back to be displayed on the device. I would really like to have access to the EPUBs XHTML, to display it in a webview. I have been able to unzip the EPUBs and browse the different chapters, but the content is still encrypted. Is there anyone that have any idea how I can accomplish this? I'm using Xcode 4.2 , Objective C/C++ Regards, EZFrag EDIT 1: I already combed through the whole RMSDK,

问题 WideVine iOS CDM Player is playing DRM Protected content. Now, iOS11 introduce a new built-in feature i.e Screen Recording.

问题 I'm currently researching the subject of encrypting and playing encrypted videos in browser. I already have some successes with castlabs' DRMToday and Shaka Player while using Widevine. Now I'm trying to encrypt video without external services using ClearKey and play it in Chrome (using whatever js player which can handle). I did manage to encrypt single mp4 file using MP4Box (and mse-eme for creating crypt configuration) but I have no idea how to play it in browser. HTML5's Video didn't even

问题 I've trying to find out how to determine which DRM system browser is using. And in fact, only chrome say it is use 'com.widevine.alpha' where IE & Safari (Win) throw error on 'requestMediaKeySystemAccess', and firefox do not even try to say it use 'com.adobe.acccess' =] function isKeySystemSupported(keySystem) { var dfd = Q.defer(); console.log('check: ', keySystem); navigator.requestMediaKeySystemAccess(keySystem, [{contentType: 'video/webm; codecs="vp9"'}]).then(function() { dfd.resolve

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed last year . I want to implement video encryption in php and play encrypted video in HTML5 video.

问题 This question is mainly about protecting the content inside my iOS app. I intend to make an app that will download a lot of content (mainly PDF files) on user request. Once these PDFs are downloaded, they will be stored locally for easy offline access. Now, I don't want anyone to get hold of the .ipa file and manage to extract the PDF files. If this is not possible, is it possible that even if they extract the PDFs, they canNOT view it or run them? I am not sure how to handle this. Any
