I want to be able to stream from 2 webcams from different angles at the same time using only one program from my laptop. Which program is the best to use, whether it's free to use or not? I have a Windows 10 laptop that is 2 years old with an i3 processor with a 500GB SSD. I have a Windows 7 laptop that is 10 years old with an i5 processor with a 500GB HHD. Which computer would be better to use?
