FAQ

Frequently Asked Questions

Yes, as long as your server's CORS policy allows cross-origin requests. Your URL is never stored or shared with anyone.
FluxPlays uses the browser's native HTML5 video engine, which can play 4K MP4 files if your device hardware supports it.
CORS errors occur when the hosting server blocks cross-origin requests. Configure your server to allow the FluxPlays domain, or use a CORS proxy.
