我使用以下JavaScript代码打开了一个网络摄像头:
const stream = await navigator.mediaDevices.getUserMedia({ /* ... */ });
是否有任何JavaScript代码停止或关闭网络摄像头?

当前回答
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();
}

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();
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; }
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。
