I was wondering if there is a software work around.

Our church uses Aster, with one workstation running the slides in the auditorium, and another workstation running our livestream. Right now, both users have to run an instance of our projection software and click through the slides manually (so the livestream can switch between the camera feeds and the presentation). What I would really like is a way for the livestream workstation to have access to the content of the first workstation's monitor, so I can import it into OBS. The low-tech solution I have considered is to put an HDMI capture card on the feed going to the projectors, and letting the second workstation get the screen capture from there. That seems a little silly, so I was wondering if there is a software work around.
