Hey there! I have an unusual setup in which I use two capture cards. One I use for capturing to OBS, then I take that card's passthrough and feed it to my AJA card for recording ProRes video through the AJA Control Room software. A recent OBS update though has broken this workflow.
When I open AJA Control Room, I am able to see my video going into the AJA card.
When I open Elgato's 4K Capture utility, I can see video in both pieces of software.
When I close 4K capture utility and open OBS, I can see video in OBS, but the AJA Control Room preview disappears and says "Device in use in other app".
My AJA Kona card is not currently set up as a source in OBS, verified by going to add an "AJA I/O Device" and the list of existing devices is empty
From the Tools drop-down menu I've checked AJA I/O Device Output settings. Both populate with a device "0 - Kona LHI (number). Below that, output is set to "select...", format is blank, pixel format is YUV-8, and Auto-Start on launch is disabled.
I suspect that OBS is grabbing the card on startup despite not being used by OBS, and takes control away from the Control Room. Does anyone have any ideas for how I can prevent this from happening?
I know that as a possible workaround I could try futzing around with doing source recording, and going down the ffmpeg parameter rabbit hole, but I would really prefer OBS just not block me from using my card in other apps unless I actually choose to use it in OBS...
OBS Log file attached.
Any advice would be extremely appreciated!
