Well actually with modern segmented streaming (HLS or DASH), you only need 2 encodes to get 2^n (for video of n segments) unique streams. The trick is you generate the manifest per user, and they each get a unique permutation.

I actually spoke to a vendor in the last month that claims to have actually deployed this and actually prosecuted pirates. Obviously this is a sales engineer pitching a product, so take it with a grain of salt, but I have no reason to believe the technology is not reasonably robust and scalable.

So then we need captures from, say, 16 users and some software to scramble all of them together.
