然后摄像头显示了，如果我有多个rtsp流，且rtsp流可能从后台获取怎么办，有没有具体代码(标签-前端|关键词-app)

Question

实现rtsp流显示在前端页面上
我先是写了一个app.js

const stream = require('node-rtsp-stream')
new stream(
    {
        name: 'video-stream',
        streamUrl: ['rtsp://admin:jsrh123456@192.168.2.100:554/Streaming/Channels/101','rtsp://admin:jsrh123456@192.168.2.100:554/Streaming/Channels/201'],//rtsp地址
        wsPort: 9999,//端口号
        ffmpegOptions: {
            '-stats': '',
            '-r': 30,//视频帧数
            '-s': '1920*1080' //视频分辨率
        }
    }
)

然后node app.js运行
vue页面

<canvas id="video"></canvas>

 mounted() {
        //开始播放
        var canvas = document.getElementById("video");
        var url = "ws://127.0.0.1:9999";//node服务ip+端口号，本机node服务默认127.0.0.1
        var player = new JSMpeg.Player(url, { canvas });
        player.play();
    },

然后摄像头显示了，但我只会显示一个，如果我有多个rtsp流，一次性页面要显示四个，且rtsp流可能从后台获取怎么办，有没有具体代码

app.js

const stream = require('node-rtsp-stream')
const urls = [
    'rtsp://admin:jsrh123456@192.168.2.100:554/Streaming/Channels/101',
    'rtsp://admin:jsrh123456@192.168.2.100:554/Streaming/Channels/201',
    'rtsp://admin:jsrh123456@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
});

vue组件

<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: {},
    computed: {
        // player() {
        //     return this.$refs.videoPlayer.player
        // },
    },
    filters: {},
    components: {
        // Video
        // videoPlayer
    },
    created() {
        // this.controlVolume()
    },
    beforeDestroy() {
        this.players.forEach(player => player.stop());
    }

}

</script>
<style scoped>
.view {
    background-color: rgb(43, 168, 188);
    width: 435px;
    /* height: 460px; */
