Chromecast 崩溃

Question

我正在制作由 Google Chromecast 提供支持的社交墙。一切正常，但几分钟后 Chromecast 突然崩溃而没有任何错误。

我设置了一个自定义接收方应用和一个发送方应用。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 css 过渡的帮助下迭代内容、显示图像和动画。

Chromecast 似乎可以处理这些事情，因为它运行得非常流畅。但就在 Chromcast 崩溃之前，应用开始卡顿、死机并最终重新启动。

我认为可能是内存泄漏导致了崩溃，所以我调查了 JavaScript 对象分配和内存分配，但一切似乎都很好。没有可识别的内存泄漏。

如前所述，JavaScript 引擎和 Chromecast 本身都不提供任何错误消息。 （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，并且它在我猜 15 分钟内没有崩溃。但我不能排除应用程序在没有图像的情况下不会崩溃。

提前感谢您的回答！

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，如果您按下它大约 10 秒钟，您可以这样做。如果你这样做，你将不得不重新设置它。还要检查 Google 为 chromecast 更新的软件。祝你好运。
