angular - Twilio LocalVideoTrack 覆盖开始和停止事件

Question

有没有办法在视频启动或停止时覆盖启动和停止事件以执行操作？

我尝试了以下但它不工作：

this.videoTrack = screenTrack as LocalVideoTrack;

this.videoTrack.stopped = function (event) {
    //TODO: disable buttons
};

this.videoTrack.started = function (event) {
    //TODO: enable buttons
};

Answer 1

这解决了它：

    this.videoTrack.once("stopped", () => {
      //TODO: disable buttons
    });

    this.videoTrack.once("started", () => {
      //TODO: enable buttons
    });
