Hi All,

I have made an interactive squash system with Pd based on Basler's high speed cameras for machine vision. I use mainly above 200fps of 5 USB-3 cameras each of them on a separate USB bus.
The balls can fly with a 200km/s speed and I hardly have a problem analyzing their position with pix_movement.
Surely the biggest problem is having a display with a similar fresh rate, but if you do not need to render the image then it is fine.
The computer is a 3GHz processor and 32MB RAM with Ubuntu 19.04 if I remember well.

Best,
Popesz

I had a glance. I was hoping to get less general advice, preferably
concrete proven setups running on Linux.
I see there are decklink drivers, are there users out there who can
report achieved framerates and latencies from Gem? Which sensor module
are they using?

Anyone has a DeckLink Duo 2 Mini for example?
