Notes and deployment guidance:

• Load and host: Paste a public M3U URL and click Load. Then:

  • Copy web player link to share an interactive, device-friendly UI.
  • Copy hosted M3U link to share a stable, CORS-enabled URL that proxies your original M3U via /api/playlist.m3u?src=...
• Web player: Uses the HTML video element with controls; for HLS (.m3u8), it falls back to hls.js when native HLS is unavailable, following recommended patterns for autoplay, muted, and playsInline on iOS 12.
• Scalability: Deploy to Vercel for global scaling. Static assets are CDN-cached; dynamic API routes here are serverless and scale horizontally. If self-hosting behind a proxy and using streaming, ensure buffering is disabled to support streaming responses 3.

Important limitation:

• The provided source URL http://192.168.31.240:8000/playlist.m3u is a private LAN address and will not be reachable from the public internet. To make it accessible online:

  • Expose it through a publicly reachable URL (e.g., your router with port forwarding plus HTTPS, a VPN with public endpoint, or upload the .m3u file to a public host like object storage), then use that URL in this app.
  • Alternatively, upload the .m3u file via the UI; the app will host it for viewing through the web player, but persistence is ephemeral without adding storage.

Next steps to productionize:

• Add persistent storage to host the playlist file (e.g., Vercel Blob or object storage) and generate permanent share links.
• Restrict the stream proxy to known domains and/or require auth to prevent open-proxy abuse.
• Optionally add periodic re-fetching and caching headers to reduce upstream load.
