引言

海康提供了vue实现插件播放视频的实例，实现取流失败了之后重新获取新的流播放视频，但是在很多情况下需要在静态HTML项目中进行视频的播放，于是引出此文。

一、项目结构

二、项目可信代码块

<a-locale-provider :locale="zh_CN">
		<a-row>
			<a-col :span="24" :md="12">
				<a-affix :offset-top="8">
					<div id="player"></div>
				</a-affix>
				<a-form-item>
					分屏
					<a-radio-group v-model="splitNum" @change="arrangeWindow">
						<a-radio-button :value="1">1x1</a-radio-button>
						<a-radio-button :value="2">2x2</a-radio-button>
						<a-radio-button :value="3" v-show="!isMoveDevice">3x3</a-radio-button>
						<a-radio-button :value="4" v-show="!isMoveDevice">4x4</a-radio-button>
					</a-radio-group>
					<a-button @click="wholeFullScreen" v-show="!isMoveDevice">整体全屏</a-button>
				</a-form-item>
			</a-col>
			<a-col :span="24" :md="12">
				<div class="actions">
					<a-tabs v-model="tabActive">
						<a-tab-pane key="mse" tab="普通模式" :disabled="!mseSupport"></a-tab-pane>
					</a-tabs>

					<a-form :label-col="labelCol" :wrapper-col="wrapperCol" v-show="tabActive !== 'log'">
						<a-form-item label="预览URL">
							<a-input v-model="urls.realplay"></a-input>
						</a-form-item>
						<a-form-item label="预览&对讲">
							<a-button id="btn-realplay" @click="realplay">开始预览</a-button>
							<a-button id="btn-realplay-stop" @click="stopPlay">停止预览</a-button>
						</a-form-item>
					</a-form>
				</div>
			</a-col>
		</a-row>
	</a-locale-provider>

JS部分：

<script>
	const { LocaleProvider, locales } = window.antd
	moment.locale('./static/js/zh-cn.js')

	const IS_MOVE_DEVICE = document.body.clientWidth < 992 // 是否移动设备
	const MSE_IS_SUPPORT = !!window.MediaSource // 是否支持mse

	const app = new Vue({
		el: '#app',
		// components: { Log },
		data() {
			return {
				zh_CN: locales.zh_CN,
				isMoveDevice: IS_MOVE_DEVICE,
				player: null,
				splitNum: IS_MOVE_DEVICE ? 1 : 2,
				mseSupport: MSE_IS_SUPPORT,
				tabActive: MSE_IS_SUPPORT ? 'mse' : 'decoder',
				labelCol: { span: 5 },
				wrapperCol: { span: 18 },
				urls: {
					realplay: 'ws://10.157.99.39:559/openUrl/HcLPta8',
				},
				muted: true,
				volume: 50,
			}
		},
		computed: {
			mode: function() {
				return this.tabActive === 'mse' ? 0 : 1
			}
		},
		methods: {
			init() {
				// 设置播放容器的宽高并监听窗口大小变化
				window.addEventListener('resize', () => {
					this.player.JS_Resize()
				})

			},
			createPlayer() {
				this.player = new window.JSPlugin({
					szId: 'player',
					szBasePath: "./",
					iMaxSplit: 4,
					iCurrentSplit: IS_MOVE_DEVICE ? 1 : 2,
					openDebug: true,
					oStyle: {
						borderSelect: IS_MOVE_DEVICE ? '#000' : '#FFCC00',
					}
				})
			},
			arrangeWindow() {
				let splitNum = this.splitNum
				this.player.JS_ArrangeWindow(splitNum).then(
						() => { console.log(`arrangeWindow to ${splitNum}x${splitNum} success`) },
						e => { console.error(e) }
				)
			},
			wholeFullScreen() {
				this.player.JS_FullScreenDisplay(true).then(
						() => { console.log(`wholeFullScreen success`) },
						e => { console.error(e) }
				)
			},
			/* 预览&对讲 */
			realplay() {
				let { player, mode, urls } = this,
						index = player.currentWindowIndex,
						playURL = urls.realplay

				player.JS_Play(playURL, { playURL, mode }, index).then(
						() => { console.log('realplay success') },
						e => { console.error(e) }
				)
			},
		},
		mounted() {
			this.$el.style.setProperty('display', 'block')
			this.init()
			this.createPlayer()
			this.realplay();
		}
	})
</script>

三、查看效果

由于本项目是静态H5的，所以可以直接打开html文件进行预览，效果图如下：
