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
