在 CameraManager 类定义了两个常量 MIN_FRAME_WIDTH 和 MIN_FRAME_HEIGHT 。根据需要，您应该修改它们，一切都应该工作：

The CameraManager class has two constants defined MIN_FRAME_WIDTH and MIN_FRAME_HEIGHT. You should modify them as desired and everything should work:

private static final int MIN_FRAME_WIDTH = 240;  // (your desired value here)
private static final int MIN_FRAME_HEIGHT = 240; // (your desired value here)
