Video file encryption and decryption

[Gurwar]

Problem description:

I am working on an application for the Quest 2 that may require users to download video files
to their device and use AV Pro to stream it from a local file. This file would not be in the streaming assets
directory of the APK but a directory native to the Quest itself. Do you guys have any suggestions on video
encryption and decyption? So far the videos we use are accessible to users and this leaves the application
unsafe. Is there any technique within the asset itself to solve this problem or will I need to look at a third party?
crash?

Device (which devices are you having the issue with - model, OS version number):

Quest 2, PC

Media (tell us about your videos - number of videos, resolution, codec, frame-rate, example URLs):

Hi @Gurwar

There are a couple of options for content protect: https://www.renderheads.com/content/docs/AVProVideo/articles/feature-content-protection-ultra.html
