What is Movi-Player? ​

Movi-Player is a modern, modular video player for the web powered by WebCodecs and FFmpeg WASM.

The Problem ​

Traditional web video players have limitations:

  • 🚫 Limited Format Support - Only MP4/WebM with specific codecs
  • 🚫 No HDR - Can't detect or render HDR content
  • 🚫 Server Processing - Need backend for format conversion
  • 🚫 Large Bundle - All-or-nothing approach
