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?

问题 To prevent the casual distribution of pdf document, is there any way such as embedding the serial number to the file? My idea is to embed the id bound to user and enable to find who distribute the file. I know it's not preventing the distribution but may discourage the casual distribution by the certain level. Any other solution is also welcome. Thanks! 回答1: Common way is placing of meta data, but you can easily remove them. Let's search hideouts (most of them low-level)! Non-mark text Text

问题 I'm trying to find informations about the compatibility with DRM protected content and the MediaProjection API. Specifically, I would like to know if I can record the video from Netflix or other apps that implement DRM protection? 回答1: Simple answer is no, not too surprisingly.
