Recording shows only black in the background

Nov 29, 2012 at 1:00 PM


we're trying to capture data with Ogama from  a website with the ITU Gaze Tracker.

We used a specific URL for the slideshow and the tracking data looks nice. But we don't get any background. So the website is not visible behind the tracking data.

It looks like this (in the preview, but it's the same with recorded data):


We tried to solve the problem with selecting various codecs for recoring - no difference. We also tried recording the dekstop instead. This shows a complete black background.


Any ideas?

I found a workaround:

I created short desktop recording modules. Put them one after another. Thexy have a duration of 30secs.

That works. Although, the last slide always shows black (so I just record for another 30secs when I'm done)

but you do not get desynchronized capture and fixation? What you Hardware? I have a problem with the capture. I get a long desynchronization recording and fixing? / My AMD4170 ddr3 Sata 2

Hi Lornz,
I would be interested in the URL that gets the black Background, to may track the bug down.

Hi Odins,
in the meantime I replaced the Screen Recorder with an improved Version with should drastically reduce latency Problems (also I know that solid state disks will improve Performance)

Kind regards,

The URL does not matter, it's every Website I tried.

Hi Lornz, on some systems the screen recorder dlls were not correctly registered during installation.
Try the following:
Start the command line with admin rights and register the files: and with the command regsvr32. You have to get the message "successfully registered".
Check after the recording you have video files in the thumbs subfolder of your project.
