RTSP流媒体播放器_代码007(未授权)

rtsp主要还是运用ffmpeg来搭建 node后端转发到前端，前端再播放这样的思路。

这里讲的到是用两种方式，一种是ffmpeg 设置成全局来实现，一种是ffmpeg放在本地目录用相对路径来引用的方式。

ffmpeg 下载地址：http://www.ffmpeg.org/download.html
jsmpeg 下载地址：https://jsmpeg.com/jsmpeg.min.js

1） Linux下先安装 ffmpeg，详情可参考以下地址，一定要配置成全局可用。参考文档
 https://blog.csdn.net/wang y on g pro/ar ti cle/de tail s/104036835

2）如何配置window 版本 ffmpeg 全局可用，先下载 ffmpeg，找到 ffmpeg里的路径：ffmpeg bin 然后加入你的环境变量 path里。

const Stream=require('node-rtsp-stream');
// 设置rtsp视频流地址
const rtsp_urls = 'rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mov'
const streams = new Stream({
  name: 'sockets',
  streamUrl: rtsp_urls,
  wsPort: 9998,
  ffmpegOptions: { // 选项ffmpeg标志
    '-stats': '', // 没有必要值的选项使用空字符串
    '-r': 30, // 具有必需值的选项指定键后面的值<br&gt;　　　　'-s':'1920*1080'
  }
})

<canvas id="video-canvas" width="1366" height="750" style="width:980px;height:544px"&gt;</canvas&gt;
export default {
  name: 'App',
  data () {
  },
  mounted () {
    require('./jsmpeg.min.js')
    const canvas = document.getElementById('video-canvas')
    var urls = 'ws://localhost:9998'
    new window.JSMpeg.Player(urls, {canvas: canvas})
  },
  beforeUnmount () {
    this.player.destory()
  }
}
</script>

var express =  require("express");
var expressWebSocket = require("express-ws");

      .on("start", function () {

      })

        // 摄像机断线的处理

      .outputFormat("flv").videoCodec("copy").noAudio().pipe(stream);
