I need to record the screen of what's happening on a first pc on a second one and use the video at the second computer running his own Ubuntu system (not sharing the screen as in remote way). I then need to launch a script at the second pc that is gonna take data from the video record.
I have checked some external HDMI cards and I plan to buy one to do the task, but I wonder if my second pc could take the video in live at a screen/smartTV working at the second pc, running a different desktop etc than the first one, where the video comes from.
