A NEW CameraView to Rule Them All | Community Feed

Allan Ritchie has built the camera control he always wanted — a single CameraView with one API surface that works on every platform Shiny targets, including Blazor WebAssembly. The control auto-starts, requests permissions itself, and supports 11 built-in image filters that apply to both the live preview and captured photos.

What you’ll learn

How CameraView runs on iOS, Android, Windows, macOS AppKit, and Blazor WASM using native platform APIs (AVFoundation, CameraX, Media Capture, getUserMedia)
Using the pluggable analyzer pipeline for barcode scanning, face detection, motion analysis, and OCR — all streaming off the UI thread with built-in back-pressure
Structured document parsing: typed records for invoices, receipts, driver’s licenses, health cards, credit cards, and passports — not raw OCR text
MVVM-friendly bindings, scan commands, and overlay views with normalized bounding boxes
Honest platform limitations to be aware of, like Android’s CameraX concurrency constraints and filter support differences
