Is it possible to switch scenes (preferably via StreamDeck) on two OBS instances (running on different machines) synchronously?
Background
To improve the reliability of our webcasts, I'd like to add a backup OBS machine which has the identical setup like the main OBS machine. The main machine has a Blackmagic Decklink Quad HDMI capture card. The backup machine would get its signals directly via NDI from the cameras in parallel. I'd use a projector in OBS on both machines to output the signals via their HDMI outputs. Both of these signals enter a HDMI switcher which is connected to an USB grabber subsequently and which is plugged to the conferencing machine/software. In case something crashes on the main OBS machine, I could switch to the backup OBS machine within a second. Therefore it would be nice to have both OBS instances operating synchronously.
