详解Vue实现直播功能
最近公司刚好在做直播，那么今天就记录一下遇到的坑，公司服务器用的亚马逊aws，所以直接看官方的api就可以了，aws官方地址aws直播api
先看下具体的实现后的效果图把
按照网上成熟的方法，使用的是video.js,然后aws做了一层封装，那么我们直接拿来使用把,这里使用vue版本的vue-video-player
先安装下相关的包
npm install vue-video-player --save
在main.js引入vue-video-player
// 第一个是videoJs的样式，后一个是vue-video-player的样式，因为考虑到我其他业务组件可能也会用到视频播放，所以就放在了main.js内
require('video.js/dist/video-js.css')
require('vue-video-player/src/custom-theme.css')
/*导入视频播放组件*/
import VideoPlayer from 'vue-video-player'
Vue.use(VideoPlayer)
导入组件，修改配置参数
<video-player
class="video-player vjs-custom-skin"
ref="videoPlayer"
:options="playerOptions"
@play="onPlayerPlay($event)"
@pause="onPlayerPause($event)"
@statechanged="playerStateChanged($event)"
></video-player>
修改参数,添加src
playerOptions: {
playbackRates: [0.7, 1.0, 1.5, 2.0], //播放速度
autoplay: false, //如果true,浏览器准备好时开始回放。
controls: true, //控制条
preload: "auto", //视频预加载
muted: true, //默认情况下将会消除任何音频。
loop: false, //导致视频一结束就重新开始。
language: "zh-CN",
aspectRatio: "16:9", // 将播放器置于流畅模式，并在计算播放器的动态大小时使用该值。值应该代表一个比例 - 用冒号分隔的两个数字（例如"16:9"或"4:3"）
fluid: true, // 当true时，Video.js player将拥有流体大小。换句话说，它将按比例缩放以适应其容器。
sources: [
{
withCredentials: false,
type: "application/x-mpegURL",
//src: this.liveSrc
src:
"https://50f5175980ea.us-east-1.playback.live-video.net/api/video/v1/us-east-1.003054160756.channel.bSt8OCsmBtFq.m3u8"
}
],
poster: this.image, //你的封面地址
//width: 200 || document.documentElement.clientWidth,
notSupportedMessage: "此视频暂无法播放，请稍后再试", //允许覆盖Video.js无法播放媒体源时显示的默认信息。
controlBar: {
timeDivider: true, // 当前时间和持续时间的分隔符
durationDisplay: true, // 显示持续时间
remainingTimeDisplay: false, // 是否显示剩余时间功能
fullscreenToggle: true // 是否显示全屏按钮
}
},
注意要先测试直播源可以成功播放才可以，否则就会报下这些错误
那么我们先按照官方的搭建一个本地的直播源测试吧
先搭建html界面,注意要引入相关的js库和文件，我这里用hbuilder，因为用的比较顺手，而且预览模式类似于开了一个端口，通过get方式的方法，返回了一个本地服务，而不是直接本地双击打开html文件，访问静态文件哦~~~~
<!doctype html>
<html lang="en">
<head>
<link href="https://cdnjs.cloudflare.com/ajax/libs/video.js/7.11.4/video-js.css" rel="stylesheet">
<script src="https://cdnjs.cloudflare.com/ajax/libs/video.js/7.11.4/video.min.js"></script>
<script src="https://player.live-video.net/1.4.0/amazon-ivs-videojs-tech.min.js"></script>
</head>
<body>
<div class="video-container">
<video id="amazon-ivs-videojs" class="video-js vjs-4-3 vjs-big-play-centered" controls autoplay playsinline></video>
</div>
<style>
body {
margin: 0;
}
.video-container {
width: 640px;
height: 480px;
margin: 15px;
}
</style>
<script>
(function play() {
// Get playback URL from Amazon IVS API
//var PLAYBACK_URL = 'https://50f5175980ea.us-east-1.playback.live-video.net/api/video/v1/us-east-1.003054160756.channel.bSt8OCsmBtFq.m3u8';
var PLAYBACK_URL = 'https://50f5175980ea.us-east-1.playback.live-video.net/api/video/v1/us-east-1.003054160756.channel.bSt8OCsmBtFq.m3u8'
// Register Amazon IVS as playback technology for Video.js
registerIVSTech(videojs);
// Initialize player
var player = videojs('amazon-ivs-videojs', {
techOrder: ["AmazonIVS"]
}, () => {
console.log('Player is ready to use!');
// Play stream
player.src(PLAYBACK_URL);
});
})();
</script>
</body>
</html>
通过端口访问，
后来发现通过本地静态文件，也可以实现在线直播源播放
ps：如果不想自己搭建本机服务测试，也可以直接使用awd提供的在线测试
https://replit.com/@changdong0524/amazon-ivs-player-web-sample#samples/common/form-control.ts，但是要自己注册账号哦
大概就是下面这样子哦
大家自己去摸索一下就会了，修改input.value为直播源地址，然后在右边shell控制台启动就可以了
npm install && npm run start
效果如下，是一模一样的
load这里的地址换成你自己的直播源m3u8格式就好了，我这里是已经搭建好的在线直播源
直播源没问题后，接下来就直接继续写项目代码
<template>
<div class='demo'>
<video-player class="video-player vjs-custom-skin"
ref="videoPlayer"
:playsinline="true"
:options="playerOptions"
@play="onPlayerPlay($event)"
@pause="onPlayerPause($event)"
@ended="onPlayerEnded($event)"
@waiting="onPlayerWaiting($event)"
@playing="onPlayerPlaying($event)"
@loadeddata="onPlayerLoadeddata($event)"
@timeupdate="onPlayerTimeupdate($event)"
@canplay="onPlayerCanplay($event)"
@canplaythrough="onPlayerCanplaythrough($event)"
@statechanged="playerStateChanged($event)"
@ready="playerReadied"
>
</video-player>
</div>
</template>
<script>
export default {
methods: {
// 播放回调
onPlayerPlay(player) {
console.log('player play!', player)
},
// 暂停回调
onPlayerPause(player) {
console.log('player pause!', player)
},
// 视频播完回调
onPlayerEnded($event) {
console.log(player)
},
// DOM元素上的readyState更改导致播放停止
onPlayerWaiting($event) {
console.log(player)
},
// 已开始播放回调
onPlayerPlaying($event) {
console.log(player)
},
// 当播放器在当前播放位置下载数据时触发
onPlayerLoadeddata($event) {
console.log(player)
},
// 当前播放位置发生变化时触发。
onPlayerTimeupdate($event) {
console.log(player)
},
//媒体的readyState为HAVE_FUTURE_DATA或更高
onPlayerCanplay(player) {
// console.log('player Canplay!', player)
},
//媒体的readyState为HAVE_ENOUGH_DATA或更高。这意味着可以在不缓冲的情况下播放整个媒体文件。
onPlayerCanplaythrough(player) {
// console.log('player Canplaythrough!', player)
},
//播放状态改变回调
playerStateChanged(playerCurrentState) {
console.log('player current update state', playerCurrentState)
},
//将侦听器绑定到组件的就绪状态。与事件监听器的不同之处在于，如果ready事件已经发生，它将立即触发该函数。。
playerReadied(player) {
console.log('example player 1 readied', player);
}
},
}
</script>
定义相关的监听函数，可以根据自己需要加上，常用的有下面几个
onPlayerPlay(player) {
console.log("onPlayerPlay", player);
},
onPlayerPause(player) {
console.log("onPlayerPause", player);
},
playerStateChanged(player) {
console.log("playerStateChanged", player);
},
然后启动服务
npm run start
发现报错，无法找到相关的视频，于是发现缺少相关的库，还得加上aws的库才可以
在整个项目的index.html中加入下面的库支持文件
<link href="https://cdnjs.cloudflare.com/ajax/libs/video.js/7.11.4/video-js.css" rel="stylesheet">
<script src="https://cdnjs.cloudflare.com/ajax/libs/video.js/7.11.4/video.min.js"></script>
<script src="https://player.live-video.net/1.4.0/amazon-ivs-videojs-tech.min.js"></script>
最后完整效果就出来了
注意事项：
video-player标签的class必须设置成“video-player vjs-custom-skin”，你引入的样式才能起作用。 增加hls的支持。支持流媒体m3u8g等等格式播放。
增加hls.js支持，故此要安装依赖，如下：
npm install --save videojs-contrib-hls
这里提供下aws的官方仓库啊，需要自取哦
https://github.com/aws-samples
补充一下：如果直接在页面中实现的话，可能无法直接播放，会报错无法播放视频，我猜测可能有2个原因，见截图
1：异步获取后台返回的拉流地址的时候，需要一定的时间，这个时间直播组件已经初始化完毕，但是还没有获取到直播源地址，所以会报错找不到直播地址
2：直播组件也有自己一整套完整的生命周期，我们可以检测不同的生命周期，然后把直播源地址，在请求完毕后放入合适的时间，直播组件会一直请求这个直播地址，从而实现在线直播
这里我为了偷懒，暂时没有那么多时间去研究一下，等空了会去仔细研究一下，我是把他抽离出一个单组的子组件，通过props来实现地址的传递
效果一样一样的，也可以方便其他组件调用
最后为了方便管理，双手奉上最后的全部代码
