我已经在一个问题上呆了好几个星期了。让我解释一下上下文：
我正在尝试使用此库拍摄照片/视频(这是一个很好的库，没有问题(
现在的问题不是库，因为我在 5 台设备上尝试过，每次照片/视频都可以工作。
问题是我正在使用的"设备"，它是一个由大屏幕、一个在 Ubuntu 3.18.31 上运行的小盒子和一个外部摄像头组成的"ELO-KIT-EloView-Engine"。当我尝试拍照时，它可以工作，但是当我想录制视频时，它在 2% 的情况下不到 100 秒就崩溃了，我将其作为日志：

我真的希望有人有一个解决方案，这也可能是材料问题，我知道本机相机应用程序每次都不能很好地工作。
问题解决了！！
使用我使用的库，我可以更改 视频质量 .
而且"设备"只是不支持 480p(这意味着没有意义，哈哈(，我必须将质量值设置为"最高"(所以 720p 或 1080p(。
如果我不设置视频质量，默认质量为 480p，然后它不起作用
在本机相机上，当我更改质量视频时，我没有480p选择。
