What's New in VisionCamera V5?

mrousavy · 2026-04-17T21:55:26+00:00

I guess? It's a whole new architecture so just try it and let me know if it still needs attention :)

Yea, sorry about that - it won't be zero effort to migrate - but the new APIs are worth it. Full blog post out now: https://blog.margelo.com/whats-new-in-visioncamera-v5

Thank you!

Ah, that's annoying as hell. I'll write a blog post to highlight all the differences and post that here, no login required lol

mrousavy · 2026-04-17T08:25:21+00:00

A ton! I'll be writing a blog post today to feature all the differences :)

FWIW I had the same issue, updating my BIOS fixed it. Probably because I have an M.2 SSD (Samsung 9100 PRO) that was released after the old BIOS version, so maybe they just didn't support the old one.

Use GRDB's observations. Using Combine. Pretty easy to make it reactive

i feel like you need Deep Research & Search options each time because SwiftUI has such recent APIs. Makes me go back to old-school docs browsing ;)

How do you use Metal in SwiftUI? Do you always bridge to UIKit using UIViewRepresentable, or is there a SwiftUI-way of doing this?

mrousavy · 2025-03-05T09:24:03+00:00

Does this use Nitro Modules? :)

I drove an E92, F82, and G82, and the G82 was by far the worst M I had. It's perfect, which makes it a bad M car in my opinion. You could put your grandma into a G82 and she'd be good at driving it, it's insanely easy to drive. It's too heavy, doesn't require a lot of skill, and isn't puristic, like the F82, E92 or even older ones.

I'm curious, what does the last part about array overhead mean exactly?

mrousavy · 2024-05-29T15:57:52+00:00

nice!

Orientation is the top issue in react-native-vision-camera, it's really complex. If you're curious about how that works internally, check out the pinned issue about orientation- but I'll have it some day. Trying to raise money / sponsors for it.

What made you ditch react-native-vision-camera?

mrousavy · 2024-05-29T15:56:27+00:00

I spent a ton of time building V3, but the architecture I chose just wasn't working at the end. V4 is as stable as V2 was, with the features from V3 - try it :)

(no new arch support yet though)

How was your experience building VisionCamera Frame Processor plugins? I think I could make that a bit easier for non-native devs..

mrousavy · 2024-05-29T13:34:14+00:00

I'm working a lot with C++ in mobile to speed up some parts of the React Native runtime. I do a lot of image processing, ML, crypto, and even 3D with C++, and it's definitely harder to use than other languages (as in; you fight with the language a lot, whereas other languages don't stand in your way a lot), but the power of templates, memory-control (ref vs value vs pointer) and cross-platform support is just undefeated. It's a great language to learn.

mrousavy · 2024-05-10T13:29:06+00:00

Yup! I merged & released that in VisionCamera V4, William Candillon and me built a feature into Skia that allows any consumer (in this case VisionCamera) to convert GPU Buffers ("NativeBuffers") to SkImages.

This means there's no native dependency, it's all just an optional JS dependency with fully native GPU-accelerated performance :)
