Function produceMedia

produceMedia(
__namedParameters: ProduceMediaOptions,
): Promise<HeadlessActionResult>
Publish any MediaStream to the room — not just the camera or microphone.

clickVideo / clickAudio call getUserMedia internally, so they can only ever publish a real device. Anything else — a <canvas> capture, a <video> element playing a file, a Web Audio destination, a processed or synthesised track, a virtual camera — previously required monkey-patching navigator.mediaDevices.getUserMedia around the call, which is racy and leaks if the control throws. This publishes your stream directly.

The stream stays yours: stop its tracks when you are done, or call stopProducing to tear the producer down first.
Parameters
- __namedParameters: ProduceMediaOptions
Returns Promise<HeadlessActionResult>
Example: Publish a canvas as your camera
```
import { produceMedia } from 'mediasfu-shared';

const canvas = document.querySelector('canvas')!;
const stream = canvas.captureStream(30);
await produceMedia({ parameters, stream, kind: 'video' });
```
Example: Publish a video file's audio and video
```
const el = document.querySelector('video')!;
const stream = (el as any).captureStream();
await produceMedia({ parameters, stream, kind: 'video' });
await produceMedia({ parameters, stream, kind: 'audio' });
```
