jsmpeg

Why we included this project

For low-latency in-browser video, JSMpeg is a complete MPEG1/MP2 decoder written in JavaScript that sidesteps the buffering delays of HLS/DASH and the codec support gaps that make WebRTC or H.264 fiddly. A small embed, a script tag plus a div pointing at a .ts file or WebSocket source, gives you a player, and the WebSocket path is a clean way to push streams from ffmpeg or a camera to any modern browser, including iOS. Because the entire pipeline from demux to render is understandable in one codebase, it's also a useful reference for studying how video codecs work. It's not a general-purpose streaming solution; for static video you're better off with a standard MP4/WebM player, but for tight control over playback and realtime feeds it's a well-tested tool.
