Building a Smooth 60fps Video Player in Node.js.

A developer built a video player that runs Big Buck Bunny at 60 FPS entirely inside Node.js using a custom renderer called tessera.js. The system decodes video with ffmpeg into raw RGBA frames, streams them to Node, and renders with zero-copy buffers. The main challenge was synchronization timing—preventing frame drops and playback drift by anchoring everything to absolute time rather than using imprecise setTimeout intervals.
