play 4 videos sinchronously at once

[mariolago]

Hi all! I did read many posts here but did not find an answer. I have 4 folders with videos from my security cams (each folder from a different cam) and I would like to select some videos from all of the 4 folders to play sinchronously at once on vlc, so that I could review videos from some period from all of the 4 cams at once.

Did anybody here ever try to do this? Is it possible? This is a huge use case I think.

Thank you all!
