javascript - 在多个浏览器上测试 OpenTok flash，一个浏览器可以正常发布视频，但另一个浏览器显示黑屏

Question

连接到现有 session 时出现黑屏并且尝试发布该内容。出现 Flash“允许”/“拒绝”屏幕，但是按允许后，只有黑屏，其中有设置图标出版商部门。可能是什么问题？另一个浏览器实例也已打开并且发布正常。

如果您需要，这里是日志详细信息:

自己搞清楚了，希望对大家有帮助。在旧版本的 Flash 中，如果一个浏览器可以访问网络摄像头，其他浏览器将无法访问，因此一个浏览器上会出现黑屏，而另一个浏览器上会出现视频。

将 flash 更新到最新版本似乎已经解决了我的问题。
