我从here下载了apprtc。然后我安装了python 2.7，google-appengine-api和所有依赖项。我将所有内容添加到我的路径并运行以下命令：
dev_appserver.py apprtc
产生以下输出：

INFO 2014-04-24 21:31:35,681 sdk_update_checker.py:286] This SDK release is

但如果我现在在chrome或firefox中打开localhost：8080，会弹出以下消息：
getusermedia() failed. is this a webrtc capable browser

Local:
Remote:
getUserMedia failed with exception: getUserMedia is not defined
但如果我打开the official apprtc demo它运行正常。
我失败的原因是什么？ 谢谢！

尝试使用getuser media
navigator.getUserMedia = navigator.getUserMedia || navigator.webkitGetUserMedia || navigator.mozGetUserMedia;
