Hi,
I am trying to get RoboRealm VCam to work with my java (JMF)program all to no success.
I have the virtual driver installed as instructed on http://www.roborealm.com/help/Virtual_Camera_Driver.php
I tested the virtual driver to make sure it was properly installed by making a call to it from my program and it worked! but when i turn on RoboRealm, it does not connect to the same webcam dispite using the main camera driver?? I have also installed DirectX?
"3. RoboRealm then send its processed image to its VCam driver (ensure that the Options->Other->Activate VCam is set)" This is the part that is not working.
On the installation note it says when i call the VCam driver from my program it should only show a blank screen right? but the reverse is the case.
Please help it is urgent.
here is my program if you are interrested. It works fine.
