Proof

expo-camera

real getUserMedia preview + canvas-backed photo capture with base64 + MediaRecorder-backed video recording. recordAsync starts a MediaRecorder against the live stream (mp4 with webm fallback when video/mp4 is not supported), maxDuration auto-stops, stopRecording returns a real blob URL via URL.createObjectURL. Permissions go through navigator.permissions + getUserMedia probes. Live barcode scanning uses the lazy engine wasm reader; flash/torch/zoom remain unavailable.
