JSMpeg

JSMpeg is a lightweight JavaScript MPEG1 video decoder and player designed for low-latency video streaming directly inside web browsers using HTML5 technologies. The project decodes MPEG video and MP2 audio entirely in JavaScript, allowing real-time playback without requiring plugins or native browser codec support. It is commonly used in applications involving webcam streaming, surveillance systems, remote monitoring, game streaming, and embedded video dashboards because of its low overhead and simplicity. jsmpeg supports WebSocket streaming pipelines, enabling live video feeds to be transmitted efficiently to browser clients with minimal latency. The library is optimized for performance and compactness, making it especially useful for constrained environments and custom streaming solutions. Overall, jsmpeg provides a practical browser-based alternative for lightweight real-time media playback workflows.
