javascript - Chromecast崩溃

Question

我正在使用由Google Chromecast驱动的社交墙。一切正常，但是几分钟后，Chromecast突然崩溃，没有任何错误。

我设置了一个自定义的接收器应用程序和一个发送器应用程序。发送方应用程序基本上只是启动接收方应用程序，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，该服务器提供诸如tweet，Instagramm图片等内容。
该应用程序的工作方式类似于幻灯片演示，它可以在CSS过渡的帮助下对内容进行迭代，显示图像并为事物添加动画效果。

Chromecast运行起来非常平稳，因此看来它可以处理这些问题。但就在Chromcast崩溃之前，该应用开始结结，冻结并最终重新启动。

我以为可能是内存泄漏可能导致崩溃，所以我研究了JavaScript对象分配和内存分配，但是一切似乎都还可以。没有可识别的内存泄漏。

如上所述，JavaScript引擎和Chromecast本身均未提供任何错误消息。 (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该应用程序，并且它在大约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的情况。

预先感谢您的回答!

我遇到了类似的问题，并通过对chromecast本身的简单重置来解决。上面有一个小的重置按钮，如果您按下它约10秒钟，您将可以这样做。如果这样做，则必须重新进行设置。另外，请检查是否已针对Google的chromecast更新了软件。祝好运。
