Vue3封装Video.js组件

  话不多说直接上代码

在项目中安装Video.js

通过npm安装video.js

npm install video.js --save

Video.js组件的封装

<template>
  <div class="videoPlay">
    <video
      ref="m3u8_video"
      class="video-js vjs-default-skin vjs-big-play-centered"
      controls
    >
      <source :src="videoSrc" />
    </video>
  </div>
</template>
<script lang="ts" setup>
import { nextTick, onBeforeUnmount, onMounted, ref, watch } from "vue";
import videojs, { VideoJsPlayer } from "video.js";
import "video.js/dist/video-js.css";
import zh from "video.js/dist/lang/zh-CN.json";
const props = withDefaults(
  defineProps<{
    videoSrc: string;
    autoPlay?: boolean;
  }>(),
  { autoPlay: false }
);
const m3u8_video = ref();
let player: VideoJsPlayer;
const initPlay = async () => {
  videojs.addLanguage("zh-CN", zh);
  await nextTick();
  const options = {
    muted: true,
    controls: true,
    autoplay: true,
    loop: true,
    language: "zh-CN",
    techOrder: ["html5"],
  };
  player = videojs(m3u8_video.value, options, () => {
    videojs.log("播放器已经准备好了!");
    if (props.autoPlay && props.videoSrc) {
      player.play();
    }
    player.on("ended", () => {
      videojs.log("播放结束了!");
    });
    player.on("error", () => {
      videojs.log("播放器解析出错!");
    });
  });
};
onMounted(() => {
  initPlay();
});
//直接改变路径测试
watch(
  () => props.videoSrc,
  () => {
    player.pause();
    player.src(props.videoSrc);
    player.load();
    if (props.videoSrc) {
      player.play();
    }
  }
);
onBeforeUnmount(() => {
  player?.dispose();
});
</script>
<style lang="scss" scoped>
.videoPlay {
  width: 100%;
  height: 100%;
  .video-js {
    height: 100%;
    width: 100%;
    object-fit: fill;
  }
}

:deep(.vjs-tech) {
  object-fit: fill;
}
</style>
   

Video.js组件的使用

传入videoSrc和autoPlay参数，这里videoSrc是一段测试地址，你可以换成自己的实际视频流地址

<template>
  <div class="myVideo"><VideoJs :videoSrc="data.videoSrc" autoPlay /></div>
</template>

<script lang="ts" setup>
import { reactive } from "vue";
//找到你的组件地址引入进来
import VideoJs from "@/components/video/VideoJs.vue";
const data = reactive({
  videoSrc: "https://www.w3schools.com/html/movie.mp4",
});
</script>
<style scoped lang="scss">
.myVideo {
  width: 100%;
  height: 100%;
}
</style>
