DistroAV is an OBS Studio plugin that enables real-time network audio/video transmission using NDI technology. It implements both NDI sources (receiving streams) and NDI outputs (transmitting the main scene, preview, or per-source filters) within OBS. The architecture is a standard OBS plugin: it registers custom source, output, and filter types using the OBS API, provides a Qt-based settings dialog for configuration, and includes an automatic update checker. Key data flows involve capturing OBS video/audio frames, converting them to NDI frames using the NDI SDK (v6.3+), and sending/receiving over the network. External dependencies include the NDI runtime library, OBS Studio 31.1.1+, Qt6, and libcurl for updates. The codebase is well-structured with cross-platform CMake build system, CI/CD pipelines, and internationalization support, though it relies on a proprietary SDK and contains some legacy code paths.
modV is a desktop application for real-time audio-visual synthesis and effects processing. Built with Electron, Vue.js, and WebGL, it provides a modular environment where users can create chains of visual modules (2D, 3D, shader-based) that react to audio, MIDI, or user-defined parameters. The application features a dual-store Vuex architecture (main and worker processes) to keep the UI responsive while handling intensive graphics and audio processing in a background thread. Key capabilities include audio feature extraction via Meyda, MIDI input mapping, a plugin system for extensibility, and a preset system with seamless state switching. The project emphasizes real-time performance and flexibility for VJs, artists, and live visual performers.
