Figured I'd take a stab at this; pointed Claude at the VLC codebase, gave it a few references of WASM ports and a bunch of file formats to test on, and let it rip for a while. Bundled up as a JS package and built some UI around it. Pretty wild; can do stuff like play DVDs or Blu-Ray files in the browser

Show HN: Storyboarder (script to shotlist in minutes, with AI)

https://storyboarder.vercel.app/dashboard

This is very much a beta—with current functionality you can make projects, generate shots, and upload scripts which we can process into shotlists. Features I’m working on as we speak: character consistency, location consistency, framing and composing shots....
