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; ｝

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();

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; ｝

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();
  }

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。

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。
