   2  * PlayStation 4 Eye basic sample
   3  * If sceCameraIsAttached return 0 and you try to call sceCameraOpen you will received a invalid handle 0xFFFFFFFF...
   4  * debug is using udp log: socat udp-recv:18194 stdout on your host
   5  * change your ip to receive udp logs in sceNetInetPton function
   6  * It will open camera , it will start  and it will try to get 10 frames, then it will stop and close the camera and return
   7  * Output:
   8         debugnet Initialized
   9         Camera opened with handle: 1
