PORT 4446

WebSocket fMP4 Player

WebSocket MSE Safari OK

Most compatible. Works in all browsers including Safari. TCP fallback for restrictive networks. Frame batching for efficiency.

Launch Player →

PORT 4443

WebTransport Raw Player

WebTransport WebCodecs Ultra-Low

Lowest latency using WebCodecs API. Frame-by-frame decoding. Requires modern browser with WebTransport.

Launch Player →

PORT 4445

WebTransport fMP4 Player

WebTransport MSE

WebTransport with MediaSource Extensions. No WebCodecs needed. Balance of performance and compatibility.

Launch Player →

PORT 4448

WebSocket Raw Player

WebSocket WebCodecs

Raw H.264 frames over WebSocket. Alternative to WebTransport for restricted networks.

PORT 4444

Native QUIC (Server Only)

CLI Only moq-rs

Server-to-server relay using native QUIC. Not for browsers. Use moq-relay, moq-pub, moq-sub CLI tools.

                        moq-relay --listen :4444

Test Setup Commands

# Stream with FFmpeg
ffmpeg -re -i video.mp4 \
  -c:v libx264 -s 640x360 \
  -f flv rtmp://localhost/mystream

# Test with moq-rs tools
./hang serve --addr :4443
./hang publish video.mp4
./hang subscribe --url https://localhost:4443/mystream
            

Important Information

Firewall & Network Considerations:
Even if your browser supports WebTransport/QUIC/HTTP3, your firewall or corporate network might block UDP traffic on ports 443/4443/4445. This is why WINK Streaming implemented WebSocket fallback (TCP port 4446) - ensuring streams work even in restrictive environments. Browser support is only half the battle; network traversal is equally important.

Current Status - Technical Demo:
This is a technical demonstration of MoQ transport modes. Browser playback functionality varies by mode and browser. Some features are experimental and may not display video despite successful data transfer. This demo showcases the protocol implementation rather than production-ready playback.
