Acquiring and using/processing video image in separate VIs

[sleber]

Dear All,

First, I'd like to find out which is the best and easiest way to aquire video (imaq grab) in one VI, using one session at all, and processing the video in another VI, to gain access to the aquried video in parallel.

Secondly, I'm also curious, how to use one session throughout multiple video aquire+processing VIs, because I think it might be unnecessary to inittalize new camera sessions every time.

Thanks for all the ideas and solutions

I'd really appreciate every answer.

you can use producer consumer in labview see this

but in second loop with above method you should not make video indeed just create array of image with shift register and insert into array in this case you can save video that you want ans at the same time could process image inside this video but also regard that this will be consume huge range of CPU and RAM
also it is not possible use one session for multiple video in same time
