v5 not working on Win7 SP1: "Wait time did not was enough" & invalid pointer for screen capture

Jul 6, 2015 at 9:34 PM
Hello everyone

trying for one week now to make OGAMA v5 work on my dual-monitor, Win7 SP1, .NET 4.5 - no success. I even tried debugging the code in Visual Studio, but can't replicate the problem within VS. The problems are the same no matter which eyetracker I use, including the mouse tracker. Any ideas or pointers to how I can debug this? Thanks!

Problem 1)
I add a website slide, then start a test, but only the first page screenshot gets saved. Whenever I click on a link, I get "Wait time did not was enough" 5 seconds later, then the web page does not respond any more. I cannot replicate this error when stepping with the debugger in VS, which makes me think of a thread synchronization problem.

Problem 2)
I want to make a screen recording, but I get the message "Invalid pointer" and the following error (my Windows is in German, it says "Object pointer not set to an object instance")

Hi, sorry for having trouble with ogama.
As stated earlier, both website and desktop-recording are experimental and not recommended for studies.
Do you have a project on which the Problem 1) occurs reliable? Send it to adrian(at) and I will have a look at it.
Problem 2) ist mostly a problem with the screen recorder video capture compressor filter or another part of the direct show graph. It might also be a problem with the dual monitor setup. Did you tried it on single screen setup?
