getUserMedia() not supported in chrome

问题

I am trying to access my webcam using the getUserMedia() using my own website that run using my own ip address.

it was working fine until i tried my website again. i had tried the other demo site and the error given was getUserMedia is not supported.

Chrome version v47.0.2526.80m 32bits

I am able to access the webcam if i enter localhost instead of my ipadress. it also work in firefox.

回答1:

Chrome is requiring secure origins (HTTPS) for getUserMedia.

Starting with Chrome 47, getUserMedia() requests are only allowed from secure origins: HTTPS or localhost.

Chrome finally implemented the new navigator.mediaDevices.getUserMedia() method, but they added a security that will prevent the calls from unsecure address (non https or non localhost servers)

You will call it like this :

var video = document.querySelector('video');
navigator.mediaDevices.getUserMedia({video:true}).then(function(mediaStream){
    window.stream = mediaStream;
    video.src = URL.createObjectURL(mediaStream);
    video.play();
});

Or you can use the official webRTC polyfill adpater.js library.

var constraints = { video: true, audio: true };

navigator.mediaDevices.getUserMedia(constraints)
  .then(stream => video.srcObject = stream)
  .catch(e => console.error(e));
