Tried OBS on Ubuntu to do this kind of thing at work but it added several seconds of latency. Is this normal and how does OP's app get around this?

On Linux I use obs-v4l2sink https://github.com/CatxFish/obs-v4l2sink

On Windows I have tried OBS VirtualCam https://obsproject.com/forum/resources/obs-virtualcam.949/

Both of them work very close to real time for me.

Maybe your computer lacks hardware acceleration?

Linux is a quagmire, but latency problems on OBS boil down to needing a fast computer, with a powerful graphics card to encode, and carefully configured audio (the default pulseaudio setup is usually a problem). Using JACK or similar will fix a lot of trouble, but really you just need horsepower to process video at HD resolution in real time.
