Media-over-QUIC is a streaming protocol built upon cutting edge protocols (QUIC, HTTP3) and browser APIs (WebTransport, WebCodecs). It's slightly faster than WebRTC, has an advanced data recovery mechanism (placed at the frame level and not at the packet level), it supports additional codecs (FLAC) and is less complicated to route.
