Unity Vuforia 嘈杂相机答案

【问题标题】：Unity Vuforia Noisy CameraUnity Vuforia 嘈杂相机
【发布时间】：2016-05-31 00:19:48
【问题描述】：

我正在使用 Vuforia 和 Unity 开发一个简单的视频应用程序，但遇到了一个奇怪的问题。

App正常启动，突然相机启动有噪音；我已经在 3 台设备（2 台三星和 1 台摩托罗拉）上测试了我的应用程序，但问题仍然存在于三星设备（S6 和 S6 Edge）中，但在我的摩托罗拉设备中没有。

这是我的日志：

还有一个指向Video的链接

再一次，是一个简单的视频应用程序，带有一个按钮来截取屏幕，仅此而已。

希望有人知道如何解决这个问题。

提前致谢。

【问题讨论】：

“噪音”是什么意思？
@JoeBlow 你可以在我放在描述中的视频中看到。

【解决方案1】：

我解决了这个问题，请按照以下步骤操作：

将平台切换到 Android。
转到：播放器设置 > 播放器 > 其他设置
取消选中（自动 Api 检查）选项。
移除 Vulkan 项目（通过减号图标。）
添加 OpenGLES3 和 OpenGLES2。
