obs-studio works on OpenBSD not ready yet but as you see in the video
it is pretty working and its nice for streaming also. I would go with
ffmpeg for simple stuff
reddit / BSD

Read this first:
1)   I had to convert all sndio inputs to mono or else i would have a
strange noise !
2)    Don't try to add video capture device for your webcam its pretty
unstable and can crash the system, instead add a Window Capture and
capture ffplay window remember to add the noborder switch to ffplay if
you don't want titlebar ! Also remember to uncheck capture mouse
cursor !
3)    To capture the desktop audio /monitor you just add an sndio
input
and replace "default" with snd/0.mon , snd/1.mon for usb etc etc you
know the drill. It is better you restart obs-studio to make this work
.
