This add-on is exactly what I need.
Works somewhat well at first but after a couple hours, it starts taking over the GPU. Installing it sets to GPU encoding via nvenc, even though beforehand it's set to software x264 low cpu mode, and I can't change it because it says output is active. Also, when I close OBS, it freezes, and performance becomes a bit too low to play VR.
I would love to use this add-on in the future if the bugs and other issues are fixed. I suggest adding the ability to segment the recordings so if OBS crashes after x minutes, you still have a bunch of video files already backed up. I personally would like my recordings to be under 50 minutes so they can easily be scrubbed later.
