如果.stop()已弃用，那么我认为我们不应该像@MuazKhan剂量那样重新添加它。这是一个原因，为什么东西被弃用，不应该再使用。只需创建一个辅助函数…这是一个更es6的版本

function stopStream (stream) {
    for (let track of stream.getTracks()) { 
        track.stop()
    }
}

使用下列函数:

// stop both mic and camera
function stopBothVideoAndAudio(stream) {
    stream.getTracks().forEach(function(track) {
        if (track.readyState == 'live') {
            track.stop();
        }
    });
}

// stop only camera
function stopVideoOnly(stream) {
    stream.getTracks().forEach(function(track) {
        if (track.readyState == 'live' && track.kind === 'video') {
            track.stop();
        }
    });
}

// stop only mic
function stopAudioOnly(stream) {
    stream.getTracks().forEach(function(track) {
        if (track.readyState == 'live' && track.kind === 'audio') {
            track.stop();
        }
    });
}

有溪流形式成功的参考吗

var streamRef;

var handleVideo = function (stream) {
    streamRef = stream;
}

//this will stop video and audio both track
streamRef.getTracks().map(function (val) {
    val.stop();
});

你需要停止所有的轨迹(来自摄像头，麦克风):

localStream.getTracks().forEach(track => track.stop());

FF, Chrome和Opera已经开始通过导航器公开getUserMedia。mediaDevices现在是标准(可能会改变:)

在线演示

navigator.mediaDevices.getUserMedia({audio:true,video:true})
    .then(stream => {
        window.localStream = stream;
    })
    .catch( (err) =>{
        console.log(err);
    });
// later you can do below
// stop both video and audio
localStream.getTracks().forEach( (track) => {
track.stop();
});
// stop only audio
localStream.getAudioTracks()[0].stop();
// stop only video
localStream.getVideoTracks()[0].stop();

启动和停止网络摄像头，(更新2020 React es6)

开启Web摄像头

stopWebCamera =()=>

       //Start Web Came
      if (navigator.mediaDevices && navigator.mediaDevices.getUserMedia) {
        //use WebCam
        navigator.mediaDevices.getUserMedia({ video: true }).then(stream => {
          this.localStream = stream;
          this.video.srcObject = stream;
          this.video.play();
        });
      }
 }

停止网络摄像头或视频播放一般

stopVideo =()=>
{
        this.video.pause();
        this.video.src = "";
        this.video.srcObject = null;

         // As per new API stop all streams
        if (this.localStream)
          this.localStream.getTracks().forEach(track => track.stop());
}

停止网络摄像头功能，即使视频流:

  this.video.src = this.state.videoToTest;
  this.video.play();
