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
