Question

我正在使用由Google Chromecast提供支持的社交墙。一切运作良好，但几分钟后，Chromecast突然崩溃，没有任何错误。

我设置了自定义接收器应用和发送者应用。发送者应用程序基本上只是启动接收器应用程序，没有其他功能。

接收器应用程序基于Backbone和Marionette构建。它还使用Socket.io与服务器通信，提供诸如推文，Instagramm图片等内容。该应用程序的工作方式类似于幻灯片，它在内容上迭代，显示图像，并在css过渡的帮助下激活动画。

看起来Chromecast可以处理这些事情，因为它运行得非常顺利。但就在Chromcast崩溃之前，应用程序开始断断续续，冻结并最终重新启动。

我认为可能内存泄漏可能导致崩溃，所以我调查了JavaScript对象分配和内存分配，但一切似乎都没问题。没有可识别的内存泄漏。

如上所述，JavaScript引擎和Chromecast本身都不会提供任何错误消息。（您可以在下面找到Chromecast日志。）

还有一件事：我尝试在不显示所有图像的情况下运行应用程序，并且在我估计15分钟的时间内没有崩溃。但我不能排除没有图像的应用程序不会崩溃。

提前感谢您的回答！

Answer 1

我遇到了类似的问题，并通过简单的重置修复了chromecast本身。它上面有一个小的重置按钮，如果按下它大约10秒钟就可以这样做。如果你这样做，你将不得不重新设置它。还要检查Google针对chromecast更新的软件。祝你好运。
