Title: Webcam woes
Post by: Richard I on May 29, 2019, 06:14:21 PM

Hi All,
My webcam nettalk app problems continue
In Firefox the console is reporting this :

NT-Cam: Error getting stream NotAllowedError: The request is not allowed by the user agent or the platform in the current context.. Perhaps some other tab is already using the camera? jquery.nt-cam.js:132:15

and jquery.nt-cam.js returns this

​navigator.mediaDevices.getUserMedia(constraints)
            .then(function(stream){
                  _this.stream = stream;
                  _this.options.videoElement.srcObject = stream;
                  _this.options.videoElement.onloadedmetadata = function(e) {
                     _this.options.videoElement.play;
                  }   
               }).catch(function(err){
                  console.log('NT-Cam: Error getting stream ' + err + '. Perhaps some other tab is already using the camera?')
               })   
      } else {
         console.log('NT-Cam: getUserMedia() is not supported by your browser');
      }   
      return this;
   },


I can run the webcam successfully using IE 10
but the problem is the desire to run on  ipads!


Is there a fix for this yet ? as I have posted a similiar query some months ago...
The app is not running secure.

thanks

Hi Richard,

there were some webcam updates in 11.08, so that's good and so I'm pretty confident that side is working. Your last line though is the clue;

>> The app is not running secure.

Most browsers _require_ that the site be HTTPS before they will tolerate use of the webcam or microphone.
see https://www.digicert.com/blog/https-only-features-in-browsers/

Given that it's trivial, and free, to make the server HTTPS instead of HTTP probably your best bet is to get this sorted out first, and then re-check the webcam issue.

(The other most common problem I see with Webcams when testing on my machine is that only one tab, in one browser, can access the webcam at a time. So when I'm cross-browser testing I need to make sure to close the webcam page on one browser before I can test the next one. That's caught me out a few times... <g>)

Cheers
Bruce
