Hello,
I am trying to enable the user of my application (based on AR toolkit) to 
start the AR toolkit, stop it and restart it ... but it failed.

When Starting the AR toolkit, I just execute the following instructions :
arVideoOpen
arVideoInqSize
arParamLoad
arParamChangeSize
arInitCparam
arParamDisp
argInit
arVideoCapStart

when stopping it, I just call
         arVideoCapStop();
     arVideoClose();

and when I want to start it again, I call the same methods
arVideoOpen
arVideoInqSize
arParamLoad
arParamChangeSize
arInitCparam
arParamDisp
argInit
arVideoCapStart

but it failed on the first one : arVideoOpen.

Any explanation would be welcome.
Thanks.
E.D.

Hi,

You may not call arVideoClose() when you will restart later.
Just call arVideoCapStop() only.

>and when I want to start it again, I call the same methods
>arVideoOpen
>arVideoInqSize
>arParamLoad
>arParamChangeSize
>arInitCparam
>arParamDisp
>argInit
>arVideoCapStart

You do not need to call arVideoOpen().
