Video.js v10.0.0 beta is a ground-up rewrite merging Video.js, Plyr, Vidstack, and Media Chrome into a single modern framework. Key highlights include an 88% reduction in default bundle size (66% even without ABR), a new composable streaming engine called SPF that enables much smaller adaptive bitrate bundles, first-class React and TypeScript support, unstyled UI primitives inspired by Radix/Base UI, and a shadcn-style skin ejection system. The architecture is fully composable — unused features are tree-shaken out. Three presets ship with the beta: video, audio, and background video. New skins were designed by Plyr's creator Sam Potts. GA is targeted for mid-2026, with migration guides for Video.js v8, Plyr, Vidstack, and Media Chrome planned before then.
