import { useRoute, useRouter } from "vue-router";
import { LeftOutlined } from "@ant-design/icons-vue";
import videojs from "video.js"
import "video.js/dist/video-js.css"
const videoPlayer = ref(null)
const myPlayer = ref(null)
const route = useRoute();
const router = useRouter()
let token = route.query.token;
nextTick(() => {
  myPlayer.value = videojs(videoPlayer.value, {
    // poster: "//vjs.zencdn.net/v/oceans.png",//视频封面照片
