【问题描述】:
我需要让屏幕共享正常工作。如果是视频共享,它就可以工作。这是代码:
public n = navigator as any;
ngAfterViewInit(): void {
const video = this.myVideo.nativeElement;
let peerx: any;
this.n.getUserMedia =
this.n.getUserMedia ||
this.n.webkitGetUserMedia ||
this.n.mozGetUserMedia ||
this.n.msGetUserMedia;
}
this.n.getUserMedia( // this.n.mediaDevices.getDisplayMedia
{
video: {
madatory: {
chromeMediaSource: 'screen',
maxWidth: 1920,
maxHeight: 1080,
minAspectRatio: 1.77
},
}
},
(stream: any) => {
peerx = new SimplePeer({
initiator: location.hash === '#init',
trickle: false,
stream,
});
peerx.on('signal', (data) => {
const strData = JSON.stringify(data);
console.log(strData);
this.targetpeer = data;
});
peerx.on('stream', (streamX: any) => {
if ('srcObject' in video) {
video.srcObject = streamX;
} else {
video.src = window.URL.createObjectURL(streamX);
}
const playPromise = video.play();
if (playPromise !== undefined) {
playPromise
.then((_) => {
video.play();
})
.catch((error) => {
console.log(`Playing was prevented: ${error}`);
});
}
});
如果我将 'this.n.getUserMedia(....)' 行更改为 'this.n.mediaDevices.getDisplayMedia(...)',我不会得到 'signal'(关键我需要粘贴到客户端才能连接)。
