点对点videostream使用webrt和节点js和soket io远程video不呈现
我使用这个代码https://bitbucket.org/webrtc/codelab 。 当我尝试连接远程系统时，它会在远程video框中显示我的networking摄像机video。 任何人都可以帮助如何RTCPeerConnection工作？ 这是代码。
var localStream, localPeerConnection, remotePeerConnection; var localVideo = document.getElementById("localVideo"); var remoteVideo = document.getElementById("remoteVideo"); var startButton = document.getElementById("startButton"); var callButton = document.getElementById("callButton"); var hangupButton = document.getElementById("hangupButton"); startButton.disabled = false; callButton.disabled = true; hangupButton.disabled = true; startButton.onclick = start; callButton.onclick = call; hangupButton.onclick = hangup; function trace(text) { console.log((performance.now() / 1000).toFixed(3) + ": " + text); } function gotStream(stream){ trace("Received local stream"); localVideo.src = URL.createObjectURL(stream); localStream = stream; callButton.disabled = false; } function start() { trace("Requesting local stream"); startButton.disabled = true; getUserMedia({audio:true, video:true}, gotStream, function(error) { trace("getUserMedia error: ", error); }); } function call() { callButton.disabled = true; hangupButton.disabled = false; trace("Starting call"); if (localStream.getVideoTracks().length > 0) { trace('Using video device: ' + localStream.getVideoTracks()[0].label); } if (localStream.getAudioTracks().length > 0) { trace('Using audio device: ' + localStream.getAudioTracks()[0].label); } var servers = null; localPeerConnection = new RTCPeerConnection(servers); trace("Created local peer connection object localPeerConnection"); localPeerConnection.onicecandidate = gotLocalIceCandidate; remotePeerConnection = new RTCPeerConnection(servers); trace("Created remote peer connection object remotePeerConnection"); remotePeerConnection.onicecandidate = gotRemoteIceCandidate; remotePeerConnection.onaddstream = gotRemoteStream; localPeerConnection.addStream(localStream); trace("Added localStream to localPeerConnection"); localPeerConnection.createOffer(gotLocalDescription,handleError); } function gotLocalDescription(description){ localPeerConnection.setLocalDescription(description); trace("Offer from localPeerConnection: \n" + description.sdp); remotePeerConnection.setRemoteDescription(description); remotePeerConnection.createAnswer(gotRemoteDescription,handleError); } function gotRemoteDescription(description){ remotePeerConnection.setLocalDescription(description); trace("Answer from remotePeerConnection: \n" + description.sdp); localPeerConnection.setRemoteDescription(description); } function hangup() { trace("Ending call"); localPeerConnection.close(); remotePeerConnection.close(); localPeerConnection = null; remotePeerConnection = null; hangupButton.disabled = true; callButton.disabled = false; } function gotRemoteStream(event){ remoteVideo.src = URL.createObjectURL(event.stream); trace("Received remote stream"); } function gotLocalIceCandidate(event){ if (event.candidate) { remotePeerConnection.addIceCandidate(new RTCIceCandidate(event.candidate)); trace("Local ICE candidate: \n" + event.candidate.candidate); } } function gotRemoteIceCandidate(event){ if (event.candidate) { localPeerConnection.addIceCandidate(new RTCIceCandidate(event.candidate)); trace("Remote ICE candidate: \n " + event.candidate.candidate); } } function handleError(){} 您可以使用peer.js进行使用javascript的videostream。
