Function getParticipantMedia

getParticipantMedia(
__namedParameters: GetParticipantMediaOptions,
): Promise<MediaStream | null>
Resolve a participant's live MediaStream from a MediaSFU parameter bag.

This is the SDK-level counterpart of the getParticipantMedia helper that MediaSFU components publish through sourceParameters. That helper remains available for backwards compatibility; prefer this export when you drive the SDK headlessly (returnUI={false}) and only hold the parameter bag.

Resolution order:
1. parameters.participants matched by id, then by name.
2. The matched participant's videoID / audioID, looked up against allVideoStreams / allAudioStreams by producerId. These collections are keyed by producer id only — a participant's id is its membership id and never matches, which is why an id-keyed lookup silently returns null.
3. id treated directly as a producer id, for callers that already hold one.
Parameters
- __namedParameters: GetParticipantMediaOptions
Returns Promise<MediaStream | null>
Example
```
import { getParticipantMedia } from 'mediasfu-reactjs';

const stream = await getParticipantMedia({
  name: 'Paul',
  kind: 'video',
  parameters: sourceParameters.current,
});
if (stream) videoElement.srcObject = stream;
```
