GenICam.vin using more RAM than expected

General Questions

1

Hello,

I am currently developing an application that uses the GenICam.vin and saves images to the ringbuffer for retrieval at a later point.

I calculated that my image is using about 2MB per image (1920x1080, Mono).
But when I set the ringbuffer count to (for example) 1000 it should use about 2GB of RAM but it actually uses about 4GB!
I can reproduce this when I use the CVB Viewer.
Am i doing something wrong or am I missing something?

I am thankful for any tips.
Best regards,
L. Miller

What bit depth images are you collecting in the ringbuffer? Are they 8 bit?

Yes, they are normal 8 bit images.

Hi,

it sounds as if the driver would falsly allocate a convert buffer beside the image bufffer. I understand the camera is delivering Mono8. Could you attach your GenICam.ini. That might explain it.

Hi dusalf,

I can’t attach the GenICam.ini as file as I am a new user. But here it is.
I tested with a different camera the past days but the problem is the same.
Thanks for your help.

Hi, it seems I have found the problem: In my .ini file the UseTurboDrive is set to 1 even though I don’t use TurboDrive. Setting it to 0 fixed the problem.
