Overall, we must be coming at this with quite different expectations of what a NVR should do. Not just this but also "when the app fetches a video, the server deletes the ciphertext (in order to be memory efficient)". Some installations of my NVR software are multi-user; I personally use it from multiple devices; etc. So the idea the whole pipeline exists just to transfer event videos to a single Android device results in a system that I would not find useful.
There certainly is space for different approaches. E.g. Frigate's approach is quite different than Moonfire NVR's but obviously is useful in a lot of ways to a lot of people. But my take is that Privastead's approach is going to be pretty niche.
And my main comparison has been with security camera solutions that use their cloud solution to transfer videos (e.g., Ring). I think an open source solution that uses MLS and treats the cloud as fully untrusted is a superior alternative.
Regarding the multi-user support: yes, that's on the to-do list. A nice aspect of MLS is the notion of groups that it provides. In Privastead, each camera will have a separate MLS group and it could add multiple devices/smartphones to the group. The hub will then try to deliver the video to all devices in the group. Many aspects of the multi-user support still needs to be figured out, but it's technically feasible.
Regarding ffmpeg: I agree. I'm aware of it and I have it in my to-do list to replace that with a Rust-based implementation. In fact, I'll be looking into your retina library as one potential replacement. :-)
Yeah. I'm also frustrated with cameras in general. I've commented on this a few times here before, [1] but tl;dr: I don't even know what camera I'd recommend even if I had the perfect open source firmware to flash onto it easily.

Okay, interesting, yeah that sounds like a significant step up for most folks.

Patches very welcome. It could use more attention than I've been able to give it recently but likely will interact well with your camera model as-is.
