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();

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。

你需要停止所有的轨迹(来自摄像头，麦克风):

localStream.getTracks().forEach(track => track.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。

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; ｝
