Hi everyone.
I am using the new AJA plug-in and I am unable to get output from the card.
Unreal recognized Port 1 , Port 2, Port 3 and 4 of the KONA card.
I used AJA Control Room where the card was outputting video feed through Port 3 and 4 normally.
I can set and show the video feed source from Port 1,2 but I can not to know :how to do/config to port 3, port 4 for get the output SDI(fill+key) . Event, I dont know how to use the AJAOutputMedia object in this plugin.
Can anyone help me?
Thank you so much.
