Features

• Cross-Platform Camera Components - Acts as a high-performance cross-platform interface for integrating camera hardware and media capture into mobile apps.
• Camera Feed Decoders - Detects and decodes QR codes and barcodes in real-time directly from the live camera video stream.
• Computer Vision Libraries - Serves as a high-performance library for running AI models and real-time frame analysis on mobile camera streams.
• Real-Time Object Detection - Runs real-time object and face detection using AI models on live camera frames within React Native.
• Pixel-Buffer Memory Mapping - Maps raw camera pixel data into memory buffers accessible by both native code and JavaScript worklets for high-speed processing.
• Worklet Threading - Executes JavaScript functions on dedicated high-performance background threads to analyze camera frames without blocking the UI.
• Mobile Photo and Video Capture - Supports recording high-resolution images and video clips with customizable resolutions, aspect ratios, and frame rates.
• Real-Time Model Inference on Frames - Runs AI models and custom logic on individual camera frames for tasks like facial recognition and object detection.
• Device Hardware Integrations - Integrates native mobile application logic with camera hardware to optimize image quality and device selection.
• Camera Capture Controllers - Provides low-level controls for device selection, zoom, HDR, and night modes to optimize image capture.
• Mobile Media Capture - Enables recording high-resolution photos and videos with control over zoom, HDR, and frame rates.
• Native Bindings - Provides high-performance synchronous communication between JavaScript and native C++ camera modules using the JavaScript Interface.
• Scanning Workflows - Provides the operational workflow for capturing and processing barcode data from a live camera feed.
• Real-Time Visual Stream Processors - Streams camera frames to JavaScript worklet functions for high-performance analysis while the camera is active.
• Camera Frame Processors - Provides a system for manipulating pixel formats and applying visual shaders to live video streams.
• Frame Dropping Strategies - Manages high-frequency camera streams by discarding frames when the processing thread cannot keep up with hardware.
• Render-to-Texture Buffers - Binds camera output directly to GPU textures for low-latency previews and real-time shader overlays.
• Live Stream Overlays - Enables drawing shapes, text, and shaders directly onto the live camera stream for real-time visual feedback.
• QR Code Scanner Libraries - Provides a real-time detection and decoding system for QR codes and barcodes within a mobile camera feed.
• Visual Feed Overlays - Supports drawing shapes, text, or shaders over a real-time camera feed to provide visual feedback.
