#define CONFIG_CAMERA_ORIENTATION_SKYPE     0 #define CONFIG_CAMERA_FRONT_ORIENTATION_SKYPE     0 #define CONFIG_CAMERA_BACK_ORIENTATION_SKYPE      0

CONFIG_CAMERA_ORIENTATION_SKYPE 是宏开关，若要开启，设为 1

CONFIG_CAMERA_BACK_ORIENTATION_SKYPE 是后置摄像头的角度信息，可以设为 0、90、180、270

CONFIG_CAMERA_FRONT_ORIENTATION_SKYPE 是前置摄像头的角度信息，可以设为 0、90、180、270
