  avformat/mov : do not overwrite extradata in mov_read_glbl()
  Fixes regression from Ticket3962
  This basically favors the first global header while since 34751f8313a41bf94e004ffa9491f35d96763558
  
  it was the last. If this heuristic turns out worse, do not hesitate to revert this and
  
  reopen 3962 as a feature request for multiple STSD

• Core : Focus invalid element when validating a custom set of inputs

  16 décembre 2014, par Maks3w

  Core : Focus invalid element when validating a custom set of inputs
  Invalid element is not focused when validate a custom set of inputs and
  
  the last one is a valid input. The issue is element method, via
  
  prepareElement method, via reset method, resets errorList state after
  
  validate each input so the global state of the validator is not
  
  preserved.
  Closes #1327
  

• Connection timed out RTSP stream exited with error"

  30 septembre 2019, 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.
