Long story short - I'm trying to get my AJA KONA LHi capture card working with the latest version of OBS-studio for switching/streaming.
The PC here runs Windows Server 2019, and has all the AJA drivers and DirectShow filters installed. Also not sure if this would be relevant, but on this same machine I've also installed Blackmagic's desktop video suite (for my Intensity Pro cards) and NewTek's NDI drivers/software.
For testing, I have connected a known-good, 1080p60 HDMI source with no HDCP (a Cisco TelePresence C60) to the AJA's HDMI in port. I'm able to get a signal just fine:

I was also able to grab the video feed just fine from AJA's own ControlRoom application. However, things started going awry once I fired up OBS and added a DirectShow capture source. No output could be grabbed through OBS, and it kinda drags ControlRoom along with it - I was unable to get any output from the card in any application until I do a full system reboot.
Now there are two things that could happen to OBS. One is that I just get a black input, and the other is that OBS crashes. Here's the crash log, btw.
Toggled around all the formats within AJA ControlPanel: ARGB-8, YUV-8, YUV-10, RGB-10, RGB-12, none worked. Also tried the same in OBS, to no avail. Not sure what FourCC does, but switching it to anything within OBS doesn't seem to work as it'll just bounce back to UYVY. That being said, OBS seems to at least know the source resolution, but each time I restart OBS the video source will also go back to SDI (although I have the default set to HDMI within AJA Multi-Channel Config tool):

Edit 1 - after a reboot, I was able to get the card to at least throw out something to OBS:

Now, this still seems to crash. Upon seeing the log, it seems that something is going on with the audio:
With that, I went into the settings menu again, this time checking 'Use custom audio device' and pointing it to something else (in my case, 'Line (NewTek NDI Audio)'. Now OBS doesn't crash anymore. But while I'm able to get a live feed in the properties box, The feed still doesn't properly go into the scene (still getting a black screen there)...
Oh, and another problem: the 'input source' within OBS seems to keep bouncing back to SDI. Every. Single. Time.
Any ideas why this is not working? Color space issues? Video format issues? Something else? I've tried searching around everywhere and while there are a few mentions of OBS + AJA Kona cards (some claimed that they work), I could not find any specific technical information on how to make this happen. So, any ideas? (Thanks!)
