视频才用流媒体,有后台实时返回数据, 要支持flash播放, 所以需安装对应的flash插件。当视频播放时,每间隔3秒向后台发送请求供检测心跳,表明在线收看状态,需要后台持续发送视频数据。
1. yarn add video.js videojs-flash
2. 创建videp.js声明文件
3. 创建video_player.vue组件,供外部调用。源码如下
<script lang="ts">
import { Component, Emit, Prop, Vue } from 'vue-property-decorator';
import 'video.js/dist/video-js.css';
import _videojs from 'video.js';
const videojs = (window as any).videojs || _videojs;
import 'videojs-flash';
@Component({
name: 'video-player',
})
export default class VideoPlayer extends Vue {
/* ------------------------ INPUT & OUTPUT ------------------------ */
@Prop({ type: Object, default: () => {}}) private options!: object;
/* ------------------------ VUEX (vuex getter & vuex action) ------------------------ */
/* ------------------------ LIFECYCLE HOOKS (created & mounted & ...) ------------------------ */
private mounted() {
this.player = videojs(this.$refs.videoPlayer, this.options, function onPlayerReady() {
// console.log('onPlayerReady');
});
}
private beforeDestroy() {
if (this.player) {
this.player.dispose();
}
}
/* ------------------------ COMPONENT STATE (data & computed & model) ------------------------ */
private player: any;
/* ------------------------ WATCH ------------------------ */
/* ------------------------ METHODS ------------------------ */
}
</script>
<template>
<div class="module_video_player">
<video ref="videoPlayer" class="video-js" autoplay></video>
</div>
</template>
<style lang="stylus" scoped>
@import '~@/assets/styles/var.styl';
.module_video_player
position relative
width 780px
</style>
4. 在需要使用的模块(如show_monitor.vue)调用。组件创建后,向后台发送轻轻获取rtmp视频播放地址,并更新videoOptions中的src。触发video_player的创建、挂载等。
import VideoPlayer from '@/components/video_player.vue';
components: {
VideoPlayer,
}
private videoOptions = {
techOrder: ['flash', 'html5'],
sourceOrder: true,
flash: {
hls: { withCredentials: false },
},
html5: { hls: { withCredentials: false } },
sources: [{
type: 'rtmp/flv',
src: '', // 'rtmp://live.hkstv.hk.lxdns.com/live/hks2', // 香港卫视,可使用此地址测试
}],
autoplay: true,
controls: true,
width: '778',
height: '638',
};
<video-player :options="videoOptions" v-if="videoOptions.sources[0].src !== ''"></video-player>
5. 心跳检测
在show_monitor.vue创建时,新建定时器,每隔3秒向后台发送一个包含当前监控设备id的请求,告知后台此设备监控被调用播放。show_monitor.vue销毁时,清空定时器,后台将停止传输视频数据。
private intervalFunc: any;
private created() {
// ****
this.intervalFunc = setInterval(() => {
EquipmentService.monitor_continue_test(this.eqmtid);
}, 3000);
}
private destroyed() {
clearInterval(this.intervalFunc);
}
注: 可以再电脑安装VLC media player 下载, 播放获取到的rtmp路径,已检测数据获取是否成功
