I’m working on an app that presents a large number of short (~6Mb) video files (sequentially) to users in playlists of up to ten videos. In development, I’m just dragging a half dozen or so sample .mov files into the app, and referring to them via Bundle.main.
The app is being developed for teaching in areas with intermittent electricity and internet, so they need to be stored internally. If I continue to just drag videos in, does that mean that someone viewing the contents of the app will be able to see these individually or copy them outside the app? Is there a way to encrypt them before adding them, and then decrypt them on the fly from within the app? Or can CoreData manage this task in some way?
The expectation is that the app will be run in places where internet connectivity is available, but then taken to classrooms in rural regions of Cambodia, so preloading needs to happen in some way. So am I trying to solve the wrong problem?
The total size of all the videos could reach 3GB, so that also is a factor…
