IMediaDevices

Capture camera/mic/screen into a <video>.

Wraps: Media Capture (getUserMedia)
MDN: Media Capture and Streams API
Home: Rask.Wasm.Browser (WASM only)
Shape: one-shot
Availability: Web/Server 🟡 · PWA/WASM ✅

Capture needs transient activation + a secure (HTTPS) context, so the imperative IMediaDevices service is WASM-only. On the Server host, use the declarative MediaCaptureTrigger component — point its For: at a <video>'s ElementRef, set Audio / Video / FacingMode, and its click starts the stream and attaches it to that element inside the gesture, posting "granted" / "denied" to OnResult.

The trigger's OnStream callback hands back the started stream's MediaStreamId, which is what keeps the stream reachable from C# afterwards — stop it with IMediaStreams, re-attach it, or send it to a peer with IWebRtc. On WASM, IMediaStreamHandle.Id is the same id.

🟡 On the Server host, reachable declaratively via MediaCaptureTrigger (a click-gesture component), not as an injected service.
