Question

我正在尝试创建WebRTC视频聊天。现在我已经专注于创建媒体轨道按钮（静音视频启用或禁用视频发送，静音音频使音频相同）。这是我的代码。

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
  <script type="text/javascript" src="http://cdn.peerjs.com/0.3/peer.min.js"></script>
  <script>
  navigator.getUserMedia = navigator.getUserMedia || navigator.webkitGetUserMedia || navigator.mozGetUserMedia;

  var myStream;
  var peer = new Peer({key: 'PeerJS key'});
  var setOthersStream = function(stream){
    $('#others-video').prop('src', URL.createObjectURL(stream));
  };

  var setMyStream = function(stream){
    myStream = stream;
    $('#video').prop('src', URL.createObjectURL(stream));

  };

  peer.on('open', function(id){
    $('#peer-id').text(id);
  });

  peer.on('call', function(call){
    call.answer(myStream);
    call.on('stream', setOthersStream);
  });

  $(function(){
    navigator.getUserMedia({audio: true, video: true}, setMyStream, function(){});

    $('#call').on('click', function(){
      var call = peer.call($('#others-peer-id').val(), myStream);
      call.on('stream', setOthersStream);
    });
  });

  peer.on('error', function(e){
    console.log(e.message);
  });

有人可以指导我吗？

Answer 1

您的信息流中的视频和音轨具有您可以修改的pyautogui.dragTo(100, 100, duration=0.25) pyautogui.dragTo(200, 100, duration=0.25) pyautogui.dragTo(200, 200, duration=0.25) pyautogui.dragTo(100, 200, duration=0.25)属性。 E.g：

enabled

Answer 2

使用MediaStreamTrack.enabled。

let mic_switch = true;
let video_switch = true;

function toggleVideo() {
  if(localStream != null && localStream.getVideoTracks().length > 0){
    video_switch = !video_switch;

    localStream.getVideoTracks()[0].enabled = video_switch;
  }

}

function toggleMic() {
  if(localStream != null && localStream.getAudioTracks().length > 0){
    mic_switch = !mic_switch;

    localStream.getAudioTracks()[0].enabled = mic_switch;
  }

与远程流相同。

最后我明白了！答案的第一个答案来自＆＃34; webrtc video stream stop sharing＆＃34;引导我走向正确的方向。我创建了两个新功能来静音视频和音频，并将它们绑定到html文件中的相应按钮。最后看起来像这样：

navigator.getUserMedia = navigator.getUserMedia || navigator.webkitGetUserMedia || navigator.mozGetUserMedia;

var myStream;
var peer = new Peer({key: 'PeerJS key'});

var setOthersStream = function(stream){
  $('#others-video').prop('src', URL.createObjectURL(stream));
};

var setMyStream = function(stream){
  myStream = stream;
  $('#video').prop('src', URL.createObjectURL(stream));
};

peer.on('open', function(id){
  $('#peer-id').text(id);
});

peer.on('call', function(call){
  call.answer(myStream);
  call.on('stream', setOthersStream);
});

$(function(){
  navigator.getUserMedia({audio: true, video: true}, setMyStream, function(){});
  $('#call').on('click', function(){
    var call = peer.call($('#others-peer-id').val(), myStream);
    call.on('stream', setOthersStream);
  });
});

peer.on('error', function(e){
  console.log(e.message);
});

//create button to toggle video
var video_button = document.createElement("video_button");
video_button.appendChild(document.createTextNode("Toggle hold"));

video_button.video_onclick = function(){
  myStream.getVideoTracks()[0].enabled = !(myStream.getVideoTracks()[0].enabled);
}

var audio_button = document.createElement("audio_button");
video_button.appendChild(document.createTextNode("Toggle hold"));

audio_button.audio_onclick = function(){
  myStream.getAudioTracks()[0].enabled = !(myStream.getAudioTracks()[0].enabled);
}

希望它会对某人有所帮助。
