webrtc - tokbox : Subscriber time out error on Safari

Question

使用 opentok.js v2，视频 channel 在 Chrome 和 Firefox 上运行良好。使用的 opentok 版本来自此链接:https://static.opentok.com/v2/js/opentok.min.js

但它不适用于 safari 11.0.3。
在 session 的流创建事件中，它会生成以下错误消息“由于网络错误，流无法连接。确保您的连接没有被防火墙阻止”
发布者已成功发布，即 session.publish(..) 工作正常。

下面的代码用于进行视频通话:

this.session=OT.initSession(this.apiKey, this.sessionId);

this.session.on({

streamCreated: (event) => {

 

this.session.subscribe(event.stream, 'subscriber');

},

streamDestroyed: (event) => {

console.log(`Stream ${event.stream.name} ended because ${event.reason}`);

}

});

this.session.connect(this.token, () => {
this.publisher=OT.initPublisher('publisher');

this.session.publish(this.publisher);

});

}

opentok.js 生成的控制台中的其他异常如下:

[Error] OT.exception :: title: undefined (1554) msg: OT.Subscriber PeerConnection Error: OT.Subscriber failed to subscribe to a stream in a reasonable amount of time

以上所有错误仅在 Safari 浏览器上生成。

您需要确保已在 OpenTok 帐户门户中创建了一个 Safari 项目。更多详情请见 https://tokbox.com/developer/sdks/js/safari/

看起来您正在使用 polyfills.js 文件。如果那是来自 Angular 的包含 zone.js 的 polyfill，那么您需要在 polyfills.js 文件中包含 RTCPeerConnections 'zone.js/dist/webapis-rtc-peer-connection' 的修复程序。

import 'zone.js/dist/webapis-rtc-peer-connection';

您可能还想包含 getUserMedia 的 polyfill。更多详情请见 https://github.com/angular/zone.js/issues/948#issuecomment-357558384
