I was adjusting the obs output recording settings to send the output to udp address of the pc - but the batch file complained about input mismatch.
Glad VMIX is working, freeze may be something else but make sure you are not sending too fast or slow. Perhaps there is a difference in clock rates. Anyway, it encourages shorter overs.

OBS is a different set of problems. I tried various solutions and I settled on a a script using OBS Virtual Webcam (no sound...), OBS via FFMPEG Recording to the PC or Nano to be transcoded. This involves setting a relatively high rate in OBS, say 8Ms and getting the Nano to deal with it via a set of utilities on Evariste's git hub. You can also send HDMI to ethernet with the LKV373 or as G7JTT suggests and pick it up with the Nano to re-encode. This is what I am doing and it seems the most stable.
