Gyroflow is a cross-platform desktop and mobile application for video stabilization using gyroscope and IMU data. It ingests telemetry from a wide range of cameras (GoPro, Sony, Insta360, DJI, Canon, RED, Blackmagic, etc.), applies lens distortion correction, rolling-shutter compensation, and smoothing algorithms, then exports stabilized video via FFmpeg with GPU acceleration. The architecture is a Rust core library (gyroflow-core) with a Qt/QML GUI, GPU backends (OpenCL, wgpu/Vulkan/Metal/DirectX, Qt RHI), and a rendering pipeline supporting hardware encoding. It also includes advanced features like optical-flow-based synchronization, lens calibration, adaptive zoom, and NLE plugin installation. The codebase is large and well-structured, with trait-based algorithm dispatch for distortion models, smoothing, optical flow, and pose estimation. It demonstrates strong engineering in GPU interop, signal processing, and computer vision. However, it uses a custom Rust-like dialect (macros that transpile to Rust/C++) which increases onboarding complexity, and there are many platform-specific conditionals and some unwrap-heavy error handling. The project is actively maintained with a large community and frequent updates.
This repository is a collection of standalone web application demos from Intel showcasing the W3C Generic Sensor API (Accelerometer, Gyroscope, Magnetometer, AmbientLightSensor, OrientationSensor). The demos are built with Polymer 2/3, LitElement, Three.js, and A-Frame, and include a sensor polyfill, a sensor tester with automated test cases, a punch speed meter, a VR button using magnetometer, 360-degree panorama and video viewers, and an ambient light map. The code is functional but outdated, relying on deprecated Polymer patterns and old library versions. The primary value lies in the sensor polyfill implementation and the walking detection algorithm, which are self-contained and demonstrate non-obvious engineering skill. The repo was migrated to the W3C organization and is no longer actively maintained.
