写在前面:
之前使用过vodiejs插件播放过mp4视频格式的视频;
此次需要使用flvjs插件播放rtsp视频格式的视频;
因为视频的数据格式不同,所以对应的插件不同。
思维导图:
参考链接:rtmp、rtsp、flv、m3u8、
1.npm 安装依赖
npm i flv.js
2.使用(vue)
- <template>
- <div class="video_home">
- <video class="videoBox" muted autoplay controls ref="player">video>
- div>
- template>
-
- <script>
- import flvjs from 'flv.js' // 引入flvjs
- export default {
- data () {
- return {
- player: null
- }
- },
- mounted () {
- // 如果浏览器支持flvjs,则执行相应的程序
- if (flvjs.isSupported()) {
- // 准备监控设备流地址
- const url = 'rtsp://admin:1234567@192.168.1.100:554/Streaming/Channels/101?transportmode=unicast'
- // 创建一个flvjs实例
- // 下面的ws://localhost:8888换成你搭建的websocket服务地址,后面加上设备流地址
- this.player = flvjs.createPlayer({
- type: 'flv',
- isLive: true,
- url: 'ws://localhost:8888/' + url
- })
-
- this.player.on('error', (e) => {
- console.log(e)
- })
-
- // 将实例挂载到video元素上面
- this.player.attachMediaElement(this.$refs.player)
-
- try {
- // 开始运行加载 只要流地址正常 就可以在h5页面中播放出画面了
- this.player.load()
- this.player.play()
- } catch (error) {
- console.log(error)
- }
- }
- },
- beforeDestroy () {
- // 页面销毁前 关闭flvjs
- this.player.destroy()
- }
- }
- script>
-
- <style lang="scss" scoped>
- .video_home{
- .videoBox{
- width: 300px;
- height: 300px;
- }
- }
- style>
3.使用(react)
- import React, { useEffect, useRef } from 'react';
- import './FlvVideoPlayer.scss';
- import flvjs from 'flv.js';
- import { Button } from '@alifd/next';
-
- interface FlvVideoPlayerProps {
- url?: string; // rtsp 的url
- isNeedControl?: boolean;
- fullScreenRef?: any; // 方便组件外部调用全屏方法的ref
- }
-
- const FlvVideoPlayer = React.forwardRef
FlvVideoPlayerProps>(({ isNeedControl, url, fullScreenRef }, ref) => { - const videoDomRef = useRef
(); - const playerRef = useRef
(); // 储存player的实例 -
- React.useImperativeHandle(ref, () => ({
- requestFullscreen,
- }));
-
- useEffect(() => {
- if (videoDomRef.current) {
- if (fullScreenRef) {
- fullScreenRef.current[url] = requestFullscreen;
- }
- // const url = `${videoUrl}/rtsp/video1/?url=${url}`;
- playerRef.current = flvjs.createPlayer({
- type: 'flv',
- isLive: true,
- url,
- });
- playerRef.current.attachMediaElement(videoDomRef.current);
- try {
- playerRef.current.load();
- playerRef.current.play();
- } catch (error) {
- console.log(error);
- }
- }
-
- return () => {
- destroy();
- };
- }, [url]);
-
- /**
- * 全屏方法
- */
- const requestFullscreen = () => {
- if (videoDomRef.current) {
- (videoDomRef.current.requestFullscreen && videoDomRef.current.requestFullscreen()) ||
- (videoDomRef.current.webkitRequestFullScreen && videoDomRef.current.webkitRequestFullScreen()) ||
- (videoDomRef.current.mozRequestFullScreen && videoDomRef.current.mozRequestFullScreen()) ||
- (videoDomRef.current.msRequestFullscreen && videoDomRef.current.msRequestFullscreen());
- }
- };
-
- /**
- * 销毁flv的实例
- */
- const destroy = () => {
- if (playerRef.current) {
- playerRef.current.pause();
- playerRef.current.unload();
- playerRef.current.detachMediaElement();
- playerRef.current.destroy();
- playerRef.current = null;
- }
- };
-
- return (
- <>
- <Button type="primary" onClick={requestFullscreen}>
- 全屏按钮
- Button>
- <video controls={isNeedControl} ref={videoDomRef} className="FlvVideoPlayer" loop />
- >
- );
- });
-
- export default FlvVideoPlayer;

后端代码:
- const ffmpegPath = require('@ffmpeg-installer/ffmpeg'); // 自动为当前node服务所在的系统安装ffmpeg
- const ffmpeg = require('fluent-ffmpeg');
- const express = require('express');
- const webSocketStream = require('websocket-stream/stream');
- const expressWebSocket = require('express-ws');
-
- ffmpeg.setFfmpegPath(ffmpegPath.path);
-
- /**
- * 创建一个后端服务
- */
- function createServer() {
- const app = express();
- app.use(express.static(__dirname));
- expressWebSocket(app, null, {
- perMessageDeflate: true
- });
- app.ws('/rtsp/', rtspToFlvHandle);
-
- app.get('/', (req, response) => {
- response.send('当你看到这个页面的时候说明rtsp流媒体服务正常启动中......');
- });
-
- app.listen(8100, () => {
- console.log('转换rtsp流媒体服务启动了,服务端口号为8100');
- });
- }
-
- /**
- * rtsp 转换 flv 的处理函数
- * @param ws
- * @param req
- */
- function rtspToFlvHandle(ws, req) {
- const stream = webSocketStream(ws, {
- binary: true,
- browserBufferTimeout: 1000000
- }, {
- browserBufferTimeout: 1000000
- });
- // const url = req.query.url;
- const url = new Buffer(req.query.url, 'base64').toString(); // 前端对rtsp url进行了base64编码,此处进行解码
- console.log('rtsp url:', url);
- try {
- ffmpeg(url)
- .addInputOption(
- '-rtsp_transport', 'tcp',
- '-buffer_size', '102400'
- )
- .on('start', (commandLine) => {
- // commandLine 是完整的ffmpeg命令
- console.log(commandLine, '转码 开始');
- })
- .on('codecData', function (data) {
- console.log(data, '转码中......');
- })
- .on('progress', function (progress) {
- // console.log(progress,'转码进度')
- })
- .on('error', function (err, a, b) {
- console.log(url, '转码 错误: ', err.message);
- console.log('输入错误', a);
- console.log('输出错误', b);
- })
- .on('end', function () {
- console.log(url, '转码 结束!');
- })
- .addOutputOption(
- '-threads', '4', // 一些降低延迟的配置参数
- '-tune', 'zerolatency',
- '-preset', 'ultrafast'
- )
- .outputFormat('flv') // 转换为flv格式
- .videoCodec('libx264') // ffmpeg无法直接将h265转换为flv的,故需要先将h265转换为h264,然后再转换为flv
- .withSize('50%') // 转换之后的视频分辨率原来的50%, 如果转换出来的视频仍然延迟高,可按照文档上面的描述,自行降低分辨率
- .noAudio() // 去除声音
- .pipe(stream);
- } catch (error) {
- console.log('抛出异常', error);
- }
- }
-
- createServer();
