For our Sunday streams we run a dedicated streaming PC running OBS and Reaper. We also utilize an independent MacBook running Propresenter 7, currently on a connected server we run NDI syphon to push lower thirds into our stream. Recently OBS has been crashing when utilizing a NDI source anywhere between 10-30 minutes into the stream with no rhyme or reason why. I have removed OBS studios from %appdata%, updated plugins on both machines, and searched forum after forum with no true fix. Any direction is greatly appreciated.
