你需要停止所有的轨迹(来自摄像头，麦克风):

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

使用不同的浏览器启动网络摄像头视频

对于Opera 12

window.navigator.getUserMedia(param, function(stream) {
                            video.src =window.URL.createObjectURL(stream);
                        }, videoError );

Firefox夜间18.0

window.navigator.mozGetUserMedia(param, function(stream) {
                            video.mozSrcObject = stream;
                        }, videoError );

针对Chrome 22

window.navigator.webkitGetUserMedia(param, function(stream) {
                            video.src =window.webkitURL.createObjectURL(stream);
                        },  videoError );

使用不同浏览器停止摄像头视频

对于Opera 12

video.pause();
video.src=null;

Firefox夜间18.0

video.pause();
video.mozSrcObject=null;

针对Chrome 22

video.pause();
video.src="";

有了这个，网络摄像头的灯每次都要熄灭……

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();

您可以直接使用成功处理程序中返回给getUserMedia的流对象来结束流。如。

localMediaStream.stop()

视频。Src =""或null只会从视频标签中删除源。它不会释放硬件。

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();
});
