jquery 视频播放器 兼容苹果

安装vlc 地址https://www.videolan.org/vlc/

打开网络串流测试视频流是否可用

安装 npm install --save flv.js

1.单个flv.js dome

复制代码
<template>
    <div>
        <video class="demo-video" ref="player" muted autoplay></video>
    </div>
</template>
<script>
import flvjs from "flv.js";
export default {
    data () {
        return {
            player: null
        }
    },
    mounted () {
        if (flvjs.isSupported()) {
            let video = this.$refs.player;
            if (video) {
                this.player = flvjs.createPlayer({
                    type: "flv",
                    isLive: true,
                    url: `http://1011.hlsplay.aodianyun.com/demo/game.flv`
                });
                this.player.attachMediaElement(video);
                try {
                    this.player.load();
                    this.player.play();
                } catch (error) {
                    console.log(error);
                };
            }
        }
    },
    beforeDestroy () {
        this.player.destory();
    }
}
</script>
<style>
    .demo-video {
        max-width: 880px; 
        max-height: 660px;

2.点击列表显示相应flv流 (注：浏览器页面最多显示6个flv流 )

功能:点击右边菜单出现实时监控画面,页面有四个窗体,每个窗体播放不同的视频,当四个窗体都在播放时,点击下一个会依次替换每个窗体,随机点四个页面会出现对应的实时视频

这段代码解决了

开发问题1:离开页面视频会暂停(就没有实时性)
开发问题2:页面会疯狂报错(不影响功能,但是浏览器受不了)
开发问题3:怎么当四个窗体都在播放时,点击下一个会依次替换每个窗体
开发问题4:怎么断掉上一个视频的推流(视频会卡顿)
开发问题5:怎么断开重新连接

遇到的问题

第一种报错情况：谷歌浏览器控制台出现的报错
使用报错如下：Failed to read the ‘buffered’ property from ‘SourceBuffer’: This SourceBuffer has been removed from the parent media source.

这种错误提示一般是在flv源发生异常中断的时候产生的。错误提示大多数都在 mse-controller.js 这个模块中。
解决办法：在 mse-controller.js中（flv.js/src/core/mse-controller.js），appendMediaSegment()、_needCleanupSourceBuffer()这些方法的入口处调用检查以下MediaSource的合法性。

if (!this._mediaSource || this._mediaSource.readyState !== 'open') {
          return;
      }
