title: Unable to access camera feed in wechat browser
body: <p>I am building custom camera view to capture documents or selfies using WebRTC API.</p>
  
  <pre><code>navigator.getUserMedianavigator.mediaDevices.getUserMedia
  </code></pre>
  
  <p>My code is working fine in chrome, but when paste and open the same app link (https only) in wechat, it is failing. Since, I can't share my whole code, I am pasting some other link replicating the issue.
  Below link is working fine in chrome but not in wechat, on the same Android device.

  <p>Does wechat has any restrictions to access camera video stream? How can wechat itself able to customize camera in its "Scan QR code" feature?</p>
  
  <p><strong>Note:</strong> I am not using wechat desktop/web version. In wechat mobile app, you can share your web application link with other friends/users. once user clicks the app link, wechat will open the link in built-in wechat browser. There by users can see your application in wechat browser. My issue is - my application shows custom camera, which is not appearing in wechat browser but in chrome. 
  WeChat app already has camera permission.</p>
