我应该如何将localStream对象作为参数传递给rtcpeerconnection addtrack方法

Question

我尝试了下面的代码

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

但是它返回了这个错误

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

Answer 1

您需要添加一个音轨而不是流。API参考和示例可以在这里看到。

localStream.getTracks().forEach(track => localPeerConnection.addTrack(track));
