How should i pass a localStream object as an argument to an
rtcpeerconnection addtrack method

I tried the code below but it returned this error

JavaScript

TypeError: Argument 1 of RTCPeerConnection.addTrack does not implement interface MediaStreamTrack.

What I have tried:

JavaScript

localPeerConnection.addTrack(await localStream)
            remotePeerConnection.ontrack = () => {
                const remoteStreamVideoElement = document.querySelector("#remoteStreamVideoElement")
                remoteStreamVideoElement.srcObject = localStream
                remoteStreamVideoElement.onloadedmetadata = () => remoteStreamVideoElement.play()
            }

Solution 1

The error is telling you that whatever your localStream promise returns, it can't be passed to the addTrack method.

We can't tell you how to fix that, since you haven't shown how the localStream variable is initialized.
