VisionCamera v5 was five years in the making, and in this episode, Marc Rousavy joins Mike Grabowski to explain what changed, why v5 is more than a version bump, and how Nitro reshaped the foundation of one of the most widely used camera libraries in React Native.They cover the bridge and JSI limitations that pushed VisionCamera toward a new architecture, the move to Nitro Modules, and the API decisions behind v5. The conversation also gets into the new constraints model, output objects, in-memory photo handling, barcode scanning, migration from v4, and the testing work needed to make camera features hold up across real devices.If you build React Native camera apps, this episode is a detailed look at the engineering behind VisionCamera v5 and the decisions behind making complex camera features easier to ship and maintain.Check out episode resources on our website: https://clstk.com/3Rj0dlNCatch more React Universe On Air episodes: https://clstk.com/45ypLysSign up for our newsletter: https://clstk.com/4bktu6fFollow us on X: https://x.com/callstackioChapters:0:00 Welcome to React Universe On Air2:07 What VisionCamera is today4:51 Barcode scanning and the new Data Scanner library7:25 How VisionCamera helped shape Nitro10:55 Frame processors, C++ glue, and the old JSI era18:56 What is actually new in VisionCamera v521:45 The constraints API explained30:12 Why third-party camera apps still struggle33:29 The new output system and custom outputs37:31 Imperative API, hooks, and components39:01 Migrating from v4 to v543:25 AI, agents, and building VisionCamera v545:33 Testing, stability, and what comes next48:25 Advice for teams building camera apps50:50 Why web support is not on the roadmap
