我已经安装了 IceWeasel 以便能够测试 WebRTC。

问题

为了测试相机，我安装了luvcview显示视频流的相机

在此输入图像描述

...但是当我尝试时cheese，它确实找到了网络摄像头，需要花费大量时间来启动应用程序，但不会传输任何视频（黑色）

在此输入图像描述

...在测试 WebRTC 会话上http://opentokrtc.com/test，提示共享 Lifecam 并开始会话，但没有视频流

在此输入图像描述

它确实传递了 getMediaStream。当我刷新页面并单击“共享 MS Lifecam”时，相机亮起，但没有视频流。浏览器控制台上没有错误消息。

我该如何解决这个问题？这看起来像是驱动程序问题。

看来我已经开始解释了这里

内核太旧，无法支持高清网络摄像头
