How to prevent iOS11 Built in screen recording feature just like Amazon Prime for protected DRM content?

问题

WideVine iOS CDM Player is playing DRM Protected content. Now, iOS11 introduce a new built-in feature i.e Screen Recording. Using this feature a user can easily capture or record DRM Protected content.

I used iOS11 Beta isCaptured and UIScreenCapturedDidChange Property and try to prevent DRM protected content to recorded, But This isCaptured and UIScreenCapturedDidChange working fine when the first time I Launch my Application. Now, when I Kill my running App(Terminate the application) and Launch again then my App doesn't receive any value for isCaptured and UIScreenCapturedDidChange.

Now I try to record Netflix and Amazon Prime content using iOS11 screen recording feature but it will don't allow to record and gives a Black screen.

I want similar Black screen when screen recording is On in iOS11 device, But I don't have the solution. If anyone has then please help.

回答1:

Netflix and Amazon prime iOS apps are using Apple DRM solution for apple devices - FairPlay (https://developer.apple.com/streaming/fps/). When AVPlayer plays FairPlay encrypted content it can't be captured by Screen Recording in iOS11.

You can use UIScreen.main.isCaptured to tell if the screen is being recording by screen recording or AirPlay etc...then show your black view to cover your screen
