javascript - 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

您需要添加轨道而不是流。API 参考和示例可以在这里看到。

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