I am on OBS 27.2.4. After a lot of troubleshooting after being unable to get a 5th camera working I found that if I check "de-activate when not showing" on at least 2 of the video capture devices in the device properties, the 5th camera works fine. It makes sense that it must be 2 devices because when I tried checking that for only 1 device then when switching to that camera it goes over the limit of 4 and there's no display. When I switch to one of the cameras that only becomes active when showing, it takes about 1 second for the display to show up. I use the plugin "Auto Scene Switcher" and stream myself djing - this 1 second delay for the display to turn on does not look good - it really detracts from the experience.
Is this a known limit or is there something I can do to fix this? I have a X570 motherboard (ASUS ROG Strix X570-e gaming) and an AMD 5900x CPU - I doubt it's a bandwidth limitation. But just to check I did unplug a USB hub with a few devices connected to it and that didn't have any impact. Some of the cameras are plugged into a different USB hub - I have not tried plugging them all into direct USB ports as opposed to the hub but my troubleshooting didn't lead me to think that would make a difference, plus it would be a major pain to try that as the cords are behind a heavy desk against a wall.
