python - apprtc - getusermedia() 失败

Question

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中并运行以下命令:

dev_appserver.py apprtc

产生以下输出:

INFO     2014-04-24 21:31:34,246 sdk_update_checker.py:242] Checking for updates
to the SDK.
INFO     2014-04-24 21:31:35,681 sdk_update_checker.py:286] This SDK release is

INFO     2014-04-24 21:31:35,927 admin_server.py:117] Starting admin server at:
http://localhost:8000

但是如果我现在在 Chrome 或 Firefox 中打开 localhost:8080 ，则会弹出以下消息:

getusermedia() failed. is this a webrtc capable browser

getUserMedia failed with exception: getUserMedia is not defined

但是如果我打开the official apprtc demo运行良好。

我本地化失败的原因是什么？ 谢谢!

尝试此方法来获取用户媒体

navigator.getUserMedia = navigator.getUserMedia || navigator.webkitGetUserMedia || navigator.mozGetUserMedia;
