html5 webrtc技术详解（Html5 webRTC简单实现视频调用的示例代码）

<template>
  <video id="rtc"></video>
</template>

<script>
export default {
  name: "LiveDetails",
  data() {
    return {};
  },
  mounted() {
    let video = document.querySelector("#rtc");
    // 参数表示需要同时获取到音频和视频
    // 获取到优化后的媒体流
    // { audio: true, video: true }
    const constraints = {
      audio: { echoCancellation: { exact: false } },
      video: true
    };

    navigator.mediaDevices
      .getUserMedia(constraints)
      .then(stream => {
        console.log(stream) //此处打印请看下方
        video.srcObject = stream;

        video.onloadedmetadata = e => {
          video.play();
        };
      })
      .catch(err => {
        console.log(err);
      });
  }
