I am trying to play the video in reverse decrementing the frame number in IMAQ Read Frame function. Its working but the result is very choppy as every frame takes significant time to load, but when I just increment the frame number and play the video forward, its executing without any problem. I have attached the VI and info regarding the video, could you guys please let me know why I am having problem when I am trying to display the video in the reverse order.

New Toolkit : OpenCV wrapper for Raspberry Pi (LinuxRT) for LabVIEW
Great ! learning platform student and maker for learning machine vision application with LabVIEW.
It's working with LabVIEW Home 2014 edition and required LINX 3.0 toolkit.
You can run NI-VISION toolkit with Raspberry Pi board too.

I am new to the camera labview programming.
For my research work, I am using camera to grab the live image. I am stuck with one problem.
how to treat the background?
I tried to subtract the constant value from the entire image, but with that i am loosing few of my data.
I know one solution, but I don't know how to implement this solution.
Problem: how to take the values from the 4 corner of the image and subtract those value from entire image?
If anybody previously develop similar stuff then please help me out for this.
Any help would be appreciate.
I would like to know if there is a parameter in line scan camera which allow me to control time trigger along NI MAX or labview with imaqdx.
I mean, I would like to triggering camera during 100ms which specific shutter and specific line/sec.
And if I change shutter or line/sec the time trigger keep being the same (100ms)
I don't know if this is possible with some parameter of line scan camera.
Thanks a lot.
