• RTSP stream exited with error" : Connection timed out

  21 février 2020, par fw08

  I am building an web application on AWS Cloud that requires to stream a recorded/live video over the global network. I purchased an IP camera(GV-AVD4710) and NVR(GV-SNVR0811) for our application. In future I need to stream no. of cameras on my application.

  While Camera in use With NVR, I have connected the NVR in our local network and the camera at channel_1 of NVR. Now the lets assume NVR is getting an IP of 192.168.1.203. So for rtsp streaming URL for channel_1 will be "rtsp://id:password@192.168.1.203:554/ch1" as per manufacturer’s specification. For camera streaming I am using "ffmpeg" multimedia framework (https://github.com/xpcrts/Steaming-IP-Camera-Nodejs ). So it is working fine. I tested it and working well in local network. Code that is running on the server

  Stream = require('node-rtsp-stream')
  
  stream = new Stream({
  
      name: 'name',
  
      streamUrl: 'rtsp://ID:PASSWORD@abcxyz.com:554/ch1',
  
      wsPort:3000,
  
      ffmpegOptions: {
  
          '-stats': '',
  
          '-r': 30
  
      }
  
  })

  and Code running at client side which is independent of any plug-ins

  <div>
  
         <canvas width="auto" height="auto"></canvas>
  
         <code class="echappe-js">&lt;script type=&quot;text/javascript&quot; src='http://stackoverflow.com/feeds/tag/jsmpeg.min.js'&gt;&lt;/script&gt;
         
  &lt;script type=&quot;text/javascript&quot;&gt;<br />
  
              var canvas = document.getElementById('chanel1');<br />
  
              var websocket = new WebSocket(&quot;ws://34.202.222.188:3000&quot;);<br />
  
              var player= new jsmpeg(websocket, {canvas:canvas, autoplay:true, loop:true})<br />
  
         &lt;/script&gt;
  

  When I made this IP address available for public, and then the problem begins. It is not working and giving an error :

   "[tcp @ 0x563911f0a340] Connection to tcp://192.168.1.205:554?timeout=0 failed: Connection timed out
  
  rtsp://admin:admin@192.168.1.205: Connection timed out RTSP stream exited with error"

  In Camera Without NVR, I connected camera directly to our local network and so got an rtsp url like rtsp ://id:password@192.168.1.205/media/video1. Same happens again. Works well in local, but not working when I am making this available on public network.

  How can stream video over global network ? Is it possible to implement these logic using ffmpeg multimedia framework ? Does VLC can help in these cases ?

  I would like to reiterate that, In future there are no. of cameras needs to be stream.
