vue中web端播放rtsp视频流（摄像头监控视频）（海康威视录像机）

一、ffmpeg安装​​​​​​

ffmpeg下载 https://ffmpeg.org/download.html找ffmpeg-release-essentials.zip点击下载，下载完解压ffmpeg.exe 程序运行

二、配置ffmpeg环境变量

添加成功后验证是否生效任意地方打开cmd窗口输入 ffmpeg 打印如下表示成功

三、node搭建websocket服务

新建一个app.js文件，同级目录下npm安装 node-rtsp-stream

我是直接写在项目里了，你们可以单独写在外面

npm install node-rtsp-stream -S

app.js内容

const stream = require('node-rtsp-stream')
const urls = [
    'rtsp://admin:123456@192.168.2.100:554/Streaming/Channels/101',
    'rtsp://admin:123456@192.168.2.100:554/Streaming/Channels/201',
    'rtsp://admin:123456@192.168.2.100:554/Streaming/Channels/301'
]; // 将此处替换为实际的RTSP流地址
let wsPort = 9999; // 初始端口号
urls.forEach((url) => {
    new stream({
        name: `video-stream-${urls.indexOf(url) + 1}`,
        streamUrl: url,
        wsPort: wsPort,
        ffmpegOptions: {
            '-stats': '',
            '-r': 30,
            '-s': '1920*1080'
        }
    });
    wsPort++; // 每次递增端口号
});

运行

node app.js

这样就是成功了

四、vue播放视频

vue组件

jsmpeg.min.js下载地址

<template>
    <div class="view">
        <p>录像画面</p>
        <div id="video-container">
        </div>
    </div>
</template>

<script>
import '../../public/jsmpeg.min.js'
export default {

    data() {
        return {
            players: []
        };
    },
    methods: {
    },
    mounted() {
        //开始播放
        const container = document.getElementById('video-container');
        for (let i = 0; i < 3; i++) {
            const canvas = document.createElement('canvas');
            canvas.id = `video-${i + 1}`;
            canvas.style.width = '210px'; // 设置宽度为200px
            canvas.style.height = '210px'; // 设置高度为200px
            canvas.style.margin = '3px'; // 设置高度为200px
            container.appendChild(canvas);
            const url = `ws://127.0.0.1:${9999 + i}/video-stream-${i + 1}`;
            // const url = `ws://127.0.0.1:9999/video-stream-${i + 1}`;
            this.players.push(new JSMpeg.Player(url, { canvas }));
            this.players[i].play();
        }

    },
    watch: {},
    filters: {},
    beforeDestroy() {
        this.players.forEach(player => player.stop());
    }

}

</script>
<style scoped>
.view {
    background-color: rgb(43, 168, 188);
    box-sizing: border-box;
    
}

#video-container{
    height: 450px;

}
</style>

jsmpeg.min.js建议在index.html引入，我只是不放心又引入了一遍，正常在index.html也要引入
