FFmpeg Loading Issues?

If FFmpeg fails to load, you can try the fallback player that doesn't require FFmpeg:

Fallback mode enabled. This mode can play MP4 videos directly without conversion.

Note: MKV files will not work in fallback mode.

Troubleshooting

• FFmpeg not loading? Make sure you're using a local server (http://localhost) not file://
• Video not playing? Check that the server supports Range requests and CORS headers
• Performance issues? Reduce chunk size or max queue size on slower devices
• Browser compatibility? Use Chrome, Firefox, Edge, or Safari 11+ with WebAssembly enabled

Quick local server setup:
python -m http.server (Python 3)
python -m SimpleHTTPServer (Python 2)
npx http-server (Node.js)
Then open http://localhost:8000
