Video Easiest way to cache downloaded Videos locally on device but make them unreadable to user/public?

Hi there everyone,

Any out the box ideas for this issue?

I do not want any user just being able to copy my Mp4s to youtube. I download and cache (www) the Mp4s locally to device, each game level has it's own MP4. Best solution is putting them in in Asset Bundles. I have built this but it does not work on 2017.4.3f1 on Android. But everything else does so..... Any idea how to make these files inaccessible?

I have lots of ideas, add bytes before and after, but I'm not sure how to rebuild into object. And I'm not an Android expert and don't want to move latter Unity version after I've finally upgraded to a stable version for my game.

Hope there's an obvious solution I've missed.

Cheers

 

I could load the video file with the extra bytes and resave correctly as an Mp4. But that is a terrible solution.
