Video: Annex-B H.264/HEVC access units over a partially-reliable WebRTC DataChannel, decoded with WebCodecs in a worker.
Audio: the console's Opus as a native RTP Opus track.
Input: JSON over a reliable DataChannel (keyboard, Gamepad API with rumble, and a dual-stick multi-touch on-screen controller). Mic via the libchiaki Opus encoder.
WebSocket transport fallback for UDP-hostile networks.
Discovery / wakeup / pairing over REST; demo mode for pipeline validation.

Gated behind CHIAKI_ENABLE_WEBBRIDGE (OFF by default); self-contained under webbridge/ and consumes only the public libchiaki API. nlohmann/json and cpp-httplib are fetched via FetchContent, not vendored.

See webbridge/README.md and webbridge/PROTOCOL.md.

Note: It works pretty well! Solid latency, smoothness, and performance on Windows, Mac, and iOS Chrome browsers, even when forwarded over Cloudflare TURN relay servers.

chiaki-web is a headless bridge that embeds chiaki-lib to run a real Remote Play session and relays it to any modern browser (desktop or mobile). The browser is a thin client; the console-facing half is all libchiaki. - Video: Annex-B H.264/HEVC access units over a partially-reliable WebRTC DataChannel, decoded with WebCodecs in a worker. - Audio: the console's Opus as a native RTP Opus track. - Input: JSON over a reliable DataChannel (keyboard, Gamepad API with rumble, and a dual-stick multi-touch on-screen controller).

Hey,

I did the same thing using WASM with a proxy. Here are the sources: Chiaki-NG-Web.
