请检查这个:https://jsfiddle.net/wazb1jks/3/

导航器。getUserMedia(mediaConstraints，函数(流){ 窗口。streamReference =流; }, onMediaError);

停止记录

函数stopStream() { if (!window.streamReference)返回; window.streamReference.getAudioTracks () .forEach(函数(跟踪){ track.stop (); })； window.streamReference.getVideoTracks () .forEach(函数(跟踪){ track.stop (); })； 窗口。streamReference = null; ｝

假设我们有流式视频标签，id是video - <video id="video"></video>，那么我们应该有以下代码-

var videoEl = document.getElementById('video');
// now get the steam 
stream = videoEl.srcObject;
// now get all tracks
tracks = stream.getTracks();
// now close each track by having forEach loop
tracks.forEach(function(track) {
   // stopping every track
   track.stop();
});
// assign null to srcObject of video
videoEl.srcObject = null;

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……

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();
});

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。

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();
        }
    });
}
