Media Over QUIC (MOQ)

Using the MOQ feature with nanoStream Cloud​

Introduced in nanoStream H5Live Player Version 5.0, the Media Over QUIC (MOQ) feature adds support for next-generation transport protocols based on QUIC. MOQ is designed specifically for real-time media streaming and enables lower latency, higher reliability, and improved playback quality under unstable or changing network conditions.

MOQ builds on modern browser APIs such as WebTransport, WebCodecs, and WebAudio/Canvas, providing a new workflow optimized for live and interactive streaming at scale.

MOQ Benefits​

  • Ultra-low latency for real-time interactivity (Q&A, betting, auctions).
  • Improved stability: playback is more resilient on unstable or fluctuating networks.
  • Stream prioritization: efficient bandwidth use for video, audio, and data.
  • Future-ready: based on QUIC/HTTP/3, modernizing transport compared to TCP, HLS, or DASH.
  • Reduced packet loss impact (independent stream retransmissions).
  • Smoother adaptive bitrate playback under mobile/roaming conditions.

Browser Support​

MOQ depends on WebTransport and WebCodecs APIs in modern browsers:

  • Google Chrome, Microsoft Edge and other Chromium-based browsers (Opera, Brave, Samsung Internet, etc.): Supported in Chromium version 110 and higher.
  • Mozilla Firefox: Supported in version 130 and higher on Windows and macOS.
  • Apple Safari (macOS/iOS/iPadOS): No official support at the time (v18). Experimental feature flags already exist, but not completely working yet.

Migration Notes​

Configuration for MOQ​

MOQ playback can be controlled via new configuration settings.

'config': {
    ...
    'playback': {
        // Enabling or disabling MOQ (Media over QUIC) playback
        'enableMediaOverQuic': true, // default: true

        // Probing WebTransport/QUIC connectivity during player setup
        'enableQuicConnectionProbe': true, // default: true
    },
    ...
}
  • If enableMediaOverQuic is set to true and the browser supports it, MOQ will be used.
  • If MOQ is not available or the connection probe fails, the player will fall back to WebSocket/MSE playback.
