So has anyone downloaded 4.10 and tested it with OBS 28.1.1?
Been waiting for a while and wanted to make sure it worked/was compatible.
Also as far as install instructions...do I just download the Win x64 installer and run it?
Yep, only you need to make sure your A/V doesn't instantly delete it.
I uninstalled the old stuff, updated OBS 27 to 28.1, installed this plugin, then when firing it up it said the NDI Runtime needed to be downloaded and installed, it grabs version 5 for you, installed it, fired up OBS 28.1 again and it's there. You need to name it on the source PC and then refresh the list on the 2nd pc and it will show up. Then you can change the settings to whatever you want. It worked right from the get go but I haven't gone live with it, I only confirmed it worked perfectly when not streaming so far. I noticed OBS 28.1 has some different settings now when using NVENC by the way. So yes, OBS 28.1 works with NDI 4.10.
Like I said, make sure you name it on the source PC. Go to Tools, obs-ndi Settings, then put a checkmark in Program Output and name it whatever you want. Then refresh the list on the 2nd PC (once you've installed it over there also of course.) You will find it in the refreshed list. Oh, you need to add it as a new source on the 2nd PC first (it will offer NDI 5 Source in the Sources list.)
