WebRTC适用于FireFox，但不适用于Chrome和其他浏览器

Question

我使用SimpleWebRTC进行视频会议，但问题是FireFox工作正常，但Chrome和其他浏览器甚至不会显示允许其使用网络摄像头或麦克风的弹出窗口。

请帮我解决问题。

我的代码：

<button class="btn btn-danger" id="show" onclick="play();">btn1</button>

<video class="paused localVideo" id="localVideo"></video>
<div id="import">

</div>

<script type="text/javascript">
