I am not sure which repo is correct place to log this bug - Hello,

I have just started development in AR / VR category and using ARToolkit with Unity. I created the most simple AR tracker with hiro. Whenever I run the projet it gets stuck at above title error -

enter image description here

And this is the console details the errors ones - 

ARController (native): [error]ARWrapper::ARToolKitVideoSource::open2(): error-failed to load camera parameters camera_para.dat, calling close(), exiting returning false

Looks like the code is not able to find camera_para.dat. I find this in my AR folder, not sure if this is correct?

  • Can you run the example scene from here: ```Assets/ARToolKit5-Unity/Example Scenes/SimpleScene```? – Thor_Bux Jul 07 '17 at 02:47
  • Can you give me a screenshot of the ```ARToolKit/AR Controller/Video Options``` in the Unity Inspector window please – Thor_Bux Jul 07 '17 at 02:53
  • I am assuming you are either using a laptop front facing or a webcam. Are you positive that the drivers of the hardware are up to date an functioning properly? You could also try other software to confirm this, like `Skype`. – Hristo Jul 07 '17 at 06:36
  • Hi guys. I am using l;aptop front facing, is it a problem? Also the sample app from AR toolkit did not work. Just for reference, exporting it to APK also did not work on my mobile phone – Kaushik Ray Jul 07 '17 at 07:13
  • @KaushikRay In that case it's most likely the setup you have. What is the version of `Unity` you have and the `ARToolKit` as well? Try to upgrade to the latest possible. And is your front facing working (no its not a problem for AR)? – Hristo Jul 07 '17 at 12:10
  • hi Thanks for the answer, but front facing is working and i used the latest version. This is sad as I wanted to use this but would now need to use Vuforia which is much more stable but expesive :( – Kaushik Ray Jul 07 '17 at 19:38
  • It could be an issue with the streaming assets not finding the camera_para.dat file. Try using the latest dev build. For a lot of these issues the dev build tends to just take care of it. If its not that, this could stem from the ARController script not implementing the camera fast enough. – Joshhw Oct 04 '17 at 13:08
