Multiple USB webcam history

[grahamwebb]

Hi, I have three webcams (USB 3) connected to a Windows PC, LabVIEW 2018 with all the add-ons.I would like the ability to capture continuously from all 3 cameras 24/7, request a 'still' frame from their history (given a time t) on request from the user, and compress / store the oldest hour or so.

I've had a quick play with the vision tools - managed to capture video from multiple cameras using queues in while loops, but was unable to grab a frame in time.  

Any thoughts? 

Many thanks

Oh, that's weird. Well, don't worry, I mainly posted this comment with the intention that others find the other thread as well.

Well, I clicked on the link and went to the original, with a Solution marked.  Try going there again -- just click on this link which goes directly to the Solution.
