vue3中播放flv流视频，以及组件封装超全

实现以上功能的播放，只需要传入一个流的地址即可，当然组件也只有简单的实时播放功能

下面直接上组件

里面的flvjs通过npm i flv.js直接下载

<template>
    <div class="player" style="position: relative;">
        <p style="position: absolute !important;top: 10px;left: 20px;">通道{{ title }}</p>
        <img src="@/assets/img/videostop.png" alt="" class="centeredVideo" v-show="url == ''">
        <video  v-show="url" ref="videoElement" class="centeredVideo" controls autoplay
            muted></video>
    </div>
</template>

<script>

import flvjs from "flv.js";  //引入flv
export default {
    props: {
        title: {

        url: {

        },
    },
    data() {
        return {
            flvPlayer: null,
            // src: ["http://172.21.1.111/live?port=1935&app=myapp&stream=streamname"],
        };
    },
    mounted() {
        this.flv_load(this.url);
    },
    methods: {
        flv_load(url) {
            if (flvjs.isSupported()) {
                let videoElement = this.$refs.videoElement;
                this.flvPlayer = flvjs.createPlayer(
                    {
                        type: "flv", //媒体类型
                        url: url || '', //flv格式媒体URL

                    },
                    {
                        enableWorker: false, // 是否启用分离的线程进行转换
                        enableStashBuffer: false, //关闭IO隐藏缓冲区
                        autoCleanupSourceBuffer: true, //自动清除缓存
                    }
                );
                this.flvPlayer.attachMediaElement(videoElement); //将播放实例注册到节点
                this.flvPlayer.load(); //加载数据流
                this.flvPlayer.play(); //播放数据流
            }
        },
        //销毁断流方法
        destoryVideo() {
            if (this.flvPlayer) {
                this.flvPlayer.pause();
                this.flvPlayer.unload();
                this.flvPlayer.detachMediaElement();
                this.flvPlayer.destroy();
                this.flvPlayer = null;
            }
        },

    },
    //3.在销毁的声明周期中  必须要销毁掉播放器的容器！！！！血的教训
    beforeUnmount() {
        if (this.flvPlayer) {
            this.flvPlayer.pause();
            this.flvPlayer.unload();
            this.flvPlayer.detachMediaElement();
            this.flvPlayer.destroy();
            this.flvPlayer = null;
        }
    },
    watch: {
        url(val) {
            this.destoryVideo()
            this.flv_load(val, '变化后');
        }
    }


}

这里我封装了两个组件，一个是单个的播放，另外一个是窗口切换的

这个是窗口切换的组件

<template>

                    <el-radio-button @click="handleCount(4)" label="4" value="4" />
                    <el-radio-button @click="handleCount(6)" label="6" value="6" />

下面是实际使用方法

因为上面的组件暴露了，所以直接改组件里面的数据、直接播放了6路，下面两个arr是因为来回切换的数据需要
