当通过http连接时，在流上使用.stop()在chrome上工作。它在使用ssl (https)时不起作用。

试试下面的方法:

var mediaStream = null;
    navigator.getUserMedia(
        {
            audio: true,
            video: true
        },
        function (stream) {
            mediaStream = stream;
            mediaStream.stop = function () {
                this.getAudioTracks().forEach(function (track) {
                    track.stop();
                });
                this.getVideoTracks().forEach(function (track) { //in case... :)
                    track.stop();
                });
            };
            /*
             * Rest of your code.....
             * */
        });

    /*
    * somewhere insdie your code you call
    * */
    mediaStream.stop();

下面的代码适用于我:

public vidOff() {

      let stream = this.video.nativeElement.srcObject;
      let tracks = stream.getTracks();

      tracks.forEach(function (track) {
          track.stop();
      });

      this.video.nativeElement.srcObject = null;
      this.video.nativeElement.stop();
  }

不要使用stream.stop()，它已被弃用

MediaStream用法

使用stream.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();

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()
    }
}
