CONFIG_CAMERA_FRONT_MIRROR_MDATACB_APK 左右镜像

CONFIG_CAMERA_FRONT_FLIP_MDATACB_APK 上下翻转

#define CONFIG_CAMERA_FRONT_MIRROR_MDATACB  1
#define CONFIG_CAMERA_FRONT_MIRROR_MDATACB_ALL  0
#define CONFIG_CAMERA_FRONT_MIRROR_MDATACB_APK  "<com.skype.raider>,<com.yahoo.mobile.client.andro>,<com.tencent.mm>"
#define CONFIG_CAMERA_FRONT_FLIP_MDATACB_APK  "<com.tencent.mm>,<com.xiaomi.channel>"
#define CONFIG_CAMERA_SETVIDEOSIZE	0

一些宏开关

#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
