Function setupSenderMetadata

Installs a metadata encoder in a WebRTC RTCRtpSender to inject position information into an outgoing WebRTC audio stream.

This will install an encoder using either WebRTC Insertable Streams (e.g., Chrome, Edge) or WebRTC Encoded Transform (e.g., Safari).

The position information to inject is set by calls to HRTFOutput.setPosition.

Example

const senders = peerConnection.getSenders();
const sender = senders.find(e => e.track?.kind === 'audio');
setupSenderMetadata(sender);
