Hello everyone,
I am trying to run the following example of / jsqrcode (https://github.com/LazarSoft/jsqrcode), I created a new web app, imported the necessary JS files mentioned into the project, and modified the index.html file like this:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8"/>
<meta name="description" content="A Tizen Web UI FW single-page template generated by Tizen Web IDE"/>
<meta name="viewport" content="width=device-width,user-scalable=no"/>
<link rel="stylesheet" href="tizen-web-ui-fw/latest/themes/tizen-white/tizen-web-ui-fw-theme.css" name="tizen-theme"/>

Then I tested it with the web simulator, unfortunately, I got the camcanvas.swf window but the web cam didn't work!
I wander what's wrong with my code?
Thanks in advance.
