Question / Help NDI Gaming PC and streaming laptop not communicating

[cxboy]

Hi all, I am setting up gaming pc and streaming laptop using NDI. I got the plugins installed and they show in OBS however I am unable to get the gaming pc to be the NDI source in the streaming laptop.

Gaming PC:
CPU: i5-4690k 3.5GHz
Memory: 16GB
GPU: GTX 970

Streaming laptop:
CPU: i7-7700HQ 2.8GHz
Memory: 16GB
GPU: GTX 1050

Update Windows on gaming PC. This version is known problematic when used with OBS.

02:19:45.687: [obs-ndi] hello ! (version 4.6.2)
02:19:45.687: [obs-ndi] Trying 'C:\Program Files\NewTek\NDI 4 Runtime\v4'
02:19:45.687: [obs-ndi] Found NDI library at 'C:/Program Files/NewTek/NDI 4 Runtime/v4/Processing.NDI.Lib.x64.dll'

Update the OBS-NDI plugin. You're using the new runtime (v4) with the old plugin (4.6.2). Current is 4.7.

Same is true on the streaming PC:

19:30:50.683: [obs-ndi] hello ! (version 4.6.2)
19:30:50.683: [obs-ndi] Trying 'C:\Program Files\NewTek\NDI 4 Runtime\v4'
19:30:50.683: [obs-ndi] Found NDI library at 'C:/Program Files/NewTek/NDI 4 Runtime/v4/Processing.NDI.Lib.x64.dll'


19:30:51.196: [obs-ndi] started A/V threads for source ''
19:30:51.196: [obs-ndi] A/V thread for 'NDI™ Source' started

Log shows you've added an NDI source to the streaming PC but not selected a source. Have you just not chosen the source, or is it not available to choose. Assume both PCs are on the same LAN and firewall is allowing NDI traffic?
